ABSTRACT: This study investigates whether strategically linked performance measures reveal<br />

information about the quality of a firm’s business strategy. The strategy literature describes business<br />

strategies using the concepts of formulation, implementation, <strong>and</strong> fit. The management accounting<br />

literature links these strategy concepts with the selection <strong>and</strong> use of performance measures. Building on<br />

these two streams we examine whether <strong>and</strong> how the performance measurement system can be used to<br />

distinguish between formulation, implementation, <strong>and</strong> fit problems. We analyze balanced scorecard data<br />

from a field-site which formulated, implemented, <strong>and</strong> subsequently ab<strong>and</strong>oned an innovative operating<br />

strategy. Managers learned the strategy was ineffective over a two year period. We find that the<br />

company’s strategically linked performance measures systematically reveal more timely information<br />

about problems with the strategy. Furthermore, the performance measures distinguish between problems<br />

with strategy formulation, implementation, <strong>and</strong> fit. The results are consistent with a well implemented,<br />

but poorly formulated, strategy at the research site. Additionally, the results imply a poor fit between the<br />

strategy <strong>and</strong> the firm’s internal resources. These results provide evidence that strategically linked,<br />

balanced scorecard measures can be used (1) to evaluate the strategy promptly <strong>and</strong> (2) to distinguish<br />

between strategy formulation, implementation, <strong>and</strong> fit problems.<br />

I. INTRODUCTION<br />

Management control theories argue that performance measurement systems consisting of<br />

financial <strong>and</strong> non-financial metrics linked to the firm’s unique strategy should facilitate learning through<br />

testing, validating, <strong>and</strong> revising the hypothesized relationships that describe the strategy (e.g., Eccles<br />

1991; Kaplan <strong>and</strong> Norton 1996, 2000; Ittner <strong>and</strong> Larcker 2005; Julian <strong>and</strong> Scifres 2002; Shreyogg <strong>and</strong><br />

Steinmann 1987). For example, Kaplan <strong>and</strong> Norton (1996) contend that balanced scorecards give<br />

decision makers the ability to detect whether the company’s strategy is working or failing. We examine<br />

this idea by empirically investigating how specific information about the quality of a firm’s business<br />

strategy is revealed in strategically linked performance measures of a balanced scorecard (BSC).<br />

We conduct an ex-post audit of strategy outcome, strategy implementation, employee capability,<br />

<strong>and</strong> financial performance measures of Store24, a New Engl<strong>and</strong> convenience store chain. In FY 1998<br />

Store24 initiated a new store-level strategy to differentiate itself by improving customer experiences.<br />

There was, however, significant variation in how much <strong>and</strong> how well individual stores executed against<br />

Store24's implementation plan, in how customers valued this strategy, <strong>and</strong> in financial performance across<br />

stores. Based on customer feedback during the next two years, Store24 reverted back to a traditional<br />

strategy that emphasized speed of service <strong>and</strong> operational efficiency. Store24 monitored store<br />

performance via a set of performance measures formulated in a BSC.<br />

This site provides an ideal setting to offer empirical evidence on the extent to which strategically<br />

linked performance measures reveal specific information about a firm’s business strategy. In particular,<br />

we are able to benchmark the information revealed in analyses of the relationships among the firm’s<br />

performance measures against field-based evidence on the actual problems discovered by management<br />

over subsequent time periods.<br />

The strategy literature identifies formulation as the ends (objectives <strong>and</strong> goals) <strong>and</strong><br />

implementation as the means (action plans <strong>and</strong> allocation of resources) of the strategy (Snow <strong>and</strong><br />

Hambrick 1980). The management accounting literature on strategic control systems links these concepts<br />

of strategy formulation <strong>and</strong> implementation with the selection of performance measures. In particular, the<br />

BSC framework advocates choosing performance metrics related to key financial <strong>and</strong> customer<br />

objectives, the firm's internal processes for achieving these objectives, <strong>and</strong> organizational capabilities<br />

necessary to execute its internal processes. Moreover, performance measures should be explicitly linked<br />

in hypothesized "cause-<strong>and</strong>-effect" relationships that depict the firm's strategy (Kaplan <strong>and</strong> Norton 1996;<br />

2004). Improvements in measures of organizational capabilities are expected to drive improvements in<br />

the execution of internal processes which in turn lead to customer <strong>and</strong> financial outcomes. Thus, the BSC<br />

framework explicitly recognizes interrelationships between strategy-specific measures of financial <strong>and</strong><br />

customer outcomes <strong>and</strong> input-oriented "performance drivers" related to the firm's internal processes <strong>and</strong><br />

organizational capabilities.<br />

Managers formulate specific strategies based on ex-ante expectations about how the strategy will<br />

translate into organizational objectives (e.g., increased profitability). Moreover, managers translate these<br />

2


action plans into internal processes that will implement the formulated strategy. 1 We conceptualize the<br />

quality of strategy formulation as the marginal effect of increases in strategy specific customer outcome<br />

measures on the firm’s financial objectives. We view the quality of strategy implementation as the<br />

marginal effect of increases in input-oriented internal process measures on the firm’s strategy specific<br />

customer outcome measures. A performance measure related to internal processes may not be a leading<br />

indicator of financial performance if (1) the action plan chosen to implement the strategy, as represented<br />

by input-oriented internal process measures, does not improve specific strategic customer outcomes (poor<br />

strategy implementation) or (2) the formulated strategy improves customer outcomes, but does not deliver<br />

expected financial outcomes (poor strategy formulation).<br />

We use the framework described in the preceding paragraphs to illustrate how strategically linked<br />

performance measures in Store 24’s BSC can be used to systematically reveal information about problems<br />

with the firm’s strategy. Store24’s performance measurement system contained information to<br />

differentiate between poor strategy formulation <strong>and</strong> poor strategy implementation. As part of the<br />

customer perspective, Store24 management measured the extent to which individual stores provided an<br />

entertaining experience (i.e., a strategy-specific customer outcome measure). Store24 management also<br />

developed a store-level action plan to implement this strategy, mapped the action plan into operating<br />

st<strong>and</strong>ards, <strong>and</strong> measured store-level conformance with these st<strong>and</strong>ards as part of its BSC internal process<br />

perspective (i.e. a strategy-specific input measure). Thus, all stores worked on executing against these<br />

operating st<strong>and</strong>ards to implement the new strategy. There was, however, significant variation in how well<br />

the strategy was implemented in different stores <strong>and</strong> in how customers experienced the implementation.<br />

Measures of unique internal processes (hereafter, 'input measures') are positively related to strategy-<br />

specific customer outcome metrics (hereafter, 'outcome measures') while outcome measures are<br />

negatively related to financial performance. The results are consistent with a well implemented, but<br />

poorly formulated, strategy at our research site.<br />

performance measures, see Ittner <strong>and</strong> Larcker (2001).<br />

Theory from the strategy literature suggests that problems with a particular business strategy may<br />

arise due to lack of "fit" with internal resources such as employee capabilities (Amit <strong>and</strong> Schoemaker<br />

1993; Dierickx <strong>and</strong> Cool 1989). In this paper, strategic fit with internal resources is conceptualized in<br />

three ways. First, the marginal effect of increases in measures of a firm’s internal capabilities on strategy-<br />

specific input measures captures the extent to which the firm's internal capabilities drive its ability to<br />

execute its internal processes. Second, the marginal effect of measures of internal capabilities on the<br />

quality of strategy implementation captures complementarities between the firm's internal capabilities <strong>and</strong><br />

the processes it uses to satisfy customers. Third, the marginal effect of measures of internal capabilities<br />

on the quality of strategy formulation captures complementarities between the firm’s internal capabilities<br />

<strong>and</strong> its chosen strategy.<br />

Our results indicate that cross-sectional differences in store capabilities account for differences in<br />

the success of Store24’s strategy. Low employee skill levels do not directly affect strategy<br />

implementation. But in stores with low employee skills, even when outcome measures are high, financial<br />

performance is poor. Conversely, in stores with high employee skills, when outcome measures are high,<br />

financial performance is strong. These results are consistent with a "poor fit" hypothesis in which<br />

regardless of how thoroughly Store24 implements its strategy, for the strategy to succeed, store level<br />

employee capabilities need to be high.<br />

Our study makes three contributions to the accounting literature on performance measurement.<br />

First, we describe <strong>and</strong> illustrate a method to use performance measurement systems to analyze <strong>and</strong><br />

evaluate strategy implementation <strong>and</strong> formulation. Several studies in management accounting<br />

demonstrate relationships among financial performance metrics <strong>and</strong> non-financial measures such as<br />

product quality <strong>and</strong> customer satisfaction (e.g., Banker, et. al. 2001; Ittner <strong>and</strong> Larcker 1998b; Nagar <strong>and</strong><br />

Rajan 2001). However, these studies do not explicitly analyze measures of a firm’s strategy <strong>and</strong><br />

capabilities <strong>and</strong>, consequently, the extent to which such measures provide information useful for timely<br />

detection of problems with the strategy. In our study, contrary to prior studies, improvements in outcome<br />

4


measures are negatively (or not) related to a variety of financial measures because the strategy, though<br />

well-implemented, is poorly formulated.<br />

Second, despite the academic evidence that non-financial performance measures typically lead<br />

financial performance, Ittner <strong>and</strong> Larcker (1998b) document that many executives do not tie together<br />

firm-specific non-financial metrics with lagging accounting measures. 2 Our paper shows that the<br />

relationships between non-financial performance measures <strong>and</strong> financial performance depend on<br />

characteristics of the strategy captured by those measures. A lack of a relationship between firm-specific<br />

non-financial metrics <strong>and</strong> accounting returns may be informative about (1) the firm’s strategy<br />

formulation, (2) its strategy implementation, <strong>and</strong> (3) the effect of a firm's internal capabilities on strategy<br />

implementation or the fit of the formulated strategy with the firm’s internal capabilities. We provide<br />

some of the first field-based empirical evidence on the potential for a set of strategically linked financial<br />

<strong>and</strong> non-financial performance measures to distinguish among these three alternatives.<br />

Third, we extend prior research on the relationships between non-financial performance measures<br />

<strong>and</strong> financial performance by examining the potential moderating effect of employee capabilities. Prior<br />

research suggests that business models are typically depicted by linear relationships between financial <strong>and</strong><br />

non-financial performance metrics (Rucci et al. 1998, Kaplan <strong>and</strong> Norton 1996; 2000). Except for Ittner<br />

<strong>and</strong> Larcker (1998b), prior empirical work typically ignores potential nonlinearities in relationships<br />

among performance measures. Moreover, these studies do not examine interactions among non-financial<br />

performance measures as a source of nonlinearity that may moderate these relationships (Ittner <strong>and</strong><br />

Larcker 1998a).<br />

The results in this paper are subject to the caveat that the field-based nature of our research limits<br />

the generalizability of our findings. However, the unique nature of a firm’s strategy dictates that the<br />

performance measures <strong>and</strong> links between these measures, articulated in the firm’s business model, are<br />

likely to be firm-specific. Future research should provide additional evidence from other settings of the<br />

extent to which business model-based performance measurement systems capture information useful for<br />

2 Consistent with this, Store24 management did not perform statistical analyses linking the performance measures<br />

together, although the metrics were consistently collected across stores <strong>and</strong> across time.<br />

monitoring strategic progress. Our main contribution is to describe a method that can be generally<br />

applied to other settings <strong>and</strong> industries to isolate the effects of strategy formulation, strategy<br />

implementation, <strong>and</strong> strategic fit.<br />

The remainder of the paper proceeds as follows. In section II we discuss prior literature, <strong>and</strong> in<br />

Section III we develop hypotheses. Sections IV <strong>and</strong> V present our research site <strong>and</strong> empirical research<br />

design. Results are presented in section VI. We conclude the paper in section VII.<br />

II. THE LINK BETWEEN THE STRATEGY LITERATURE AND STRATEGIC<br />

CONTROL SYSTEMS FRAMEWORKS<br />

In this section, we discuss links among the notions of strategy formulation, implementation, <strong>and</strong><br />

fit with internal resources found in the strategy literature <strong>and</strong> emerging frameworks of strategic<br />

performance measurement found in the management accounting literature.<br />

<strong>Strategy</strong> <strong>Formulation</strong> vs. <strong>Strategy</strong> <strong>Implementation</strong><br />

There does not appear to be clear consensus on the definitions of strategy formulation <strong>and</strong><br />

strategy implementation within the strategy literature. However, several conceptual papers distinguish<br />

these concepts based on the choice of strategic objectives <strong>and</strong> the choice of action plans to achieve those<br />

objectives, respectively. Notably, Andrews (1971) put forth a general definition of strategy as:<br />

… a pattern of major objectives, purposes, or goals <strong>and</strong> essential policies <strong>and</strong><br />

plans for achieving those goals, stated in such a way as to define what business<br />

the company is in or is to be in <strong>and</strong> the kind of company it is or is to be.<br />

Andrews' definition explicitly identifies two separate processes, formulation <strong>and</strong> implementation, <strong>and</strong> the<br />

interrelation between these two concepts (Sloan 2005). Similarly, Ch<strong>and</strong>ler (1962) refers to strategy as<br />

"… the determination of the basic long-term goals <strong>and</strong> objectives of the enterprise <strong>and</strong> the adoption of<br />

courses of action <strong>and</strong> allocation of resources necessary for carrying out those goals." As with Andrews,<br />

this definition of strategy distinguishes between formulation <strong>and</strong> implementation by encompassing both<br />

elements of ends (goals <strong>and</strong> objectives) <strong>and</strong> means (courses of action <strong>and</strong> allocation of resources).<br />

Subsequent strategy researchers continue the dichotomy between choosing strategic objectives (strategy<br />

formulation) <strong>and</strong> detailing action plans to achieve those objectives (strategy implementation) (Snow <strong>and</strong><br />

Hambrick 1980).<br />

Strategic Fit with Internal Resources <strong>and</strong> Capabilities<br />

More recent research introduces a strategy’s "fit" with the firm's internal resources <strong>and</strong><br />

capabilities. The resource-based view of the firm (RBV) posits that an organization’s unique, valuable,<br />

<strong>and</strong> difficult to replicate resources <strong>and</strong> capabilities form the basis for sustainable competitive advantage<br />

(Amit <strong>and</strong> Schoemaker 1993; Dierickx <strong>and</strong> Cool 1989). 3 Others (e.g., Itami <strong>and</strong> Roehl 1987; Dierickx<br />

<strong>and</strong> Cool 1989; N<strong>and</strong>a 1996, Hitt et al. 2001) classify resources such as br<strong>and</strong> name, customer loyalty,<br />

technical know-how, firm-specific human capital, <strong>and</strong> employee skills as strategic. The RBV concept of<br />

interconnectedness of asset stocks (Dierickx <strong>and</strong> Cool 1989) posits complementarities among<br />

accumulations of various “invisible assets” or resources such as human capital. This literature focuses on<br />

the role of strategic resources <strong>and</strong> capabilities in successful strategy formulation <strong>and</strong> implementation.<br />

Strategic Control Systems <strong>and</strong> the Balanced Scorecard<br />

Recent management accounting research incorporates these strategy frameworks by articulating<br />

linkages between performance measure choice, strategy formulation, <strong>and</strong> strategy implementation. The<br />

value-based management framework (Ittner <strong>and</strong> Larcker 2001) emphasizes interrelationships among the<br />

choices of strategic objectives, action plans, <strong>and</strong> performance measures. Proponents of strategic or<br />

“business model” based performance measurement systems advocate formulating performance<br />

measurement systems around a diverse set of financial <strong>and</strong> non-financial performance metrics linked to<br />

the firm’s unique strategy (e.g., Eccles 1991; Kaplan <strong>and</strong> Norton 1996).<br />

The literature on management control systems has long argued that one role of control <strong>and</strong><br />

performance measurement systems is the facilitation of strategic feedback <strong>and</strong> learning (Ittner <strong>and</strong><br />

Larcker 2005), This literature echoes the basic means-ends concepts found in the strategy literature by<br />

emphasizing strategic feedback <strong>and</strong> learning as a process of systematically using data generated by the<br />

firm's control systems to evaluate strategic plans, activities, <strong>and</strong> ultimately, results (Schreyogg <strong>and</strong><br />

Steinmann 1987; Julian <strong>and</strong> Scifres 2002). Similarly, in settings where there is uncertainty over the firm's<br />

"profit drivers", Dye (2004) demonstrates that performance measurement systems consisting of<br />

a decentralized company in which stores are heterogeneous with respect to demographics <strong>and</strong> employee capabilities.<br />

"intermediate" measures of firm processes facilitate experimentation in that they allow managers to<br />

determine which of several underlying processes are most strongly linked to future profitability.<br />

Kaplan <strong>and</strong> Norton's (1996; 2004) BSC framework is perhaps most explicit in advocating that<br />

performance measures be chosen based on hypothesized relationships between measures of financial<br />

objectives <strong>and</strong> unique measures of nonfinancial "performance drivers". This framework can be<br />

conceptualized as consisting of strategic outcome metrics in the financial <strong>and</strong> customer perspectives <strong>and</strong><br />

strategic input metrics in the internal process <strong>and</strong> learning <strong>and</strong> growth perspectives. These measures<br />

should be explicitly linked in a series of hypothesized "cause-<strong>and</strong>-effect" relationships that represent the<br />

firm's strategy (Kaplan <strong>and</strong> Norton 1996; 2004). With its emphasis on intangible assets (e.g., employee<br />

capabilities) as the basis for successful strategy implementation, the BSC framework directly parallels the<br />

notion of "fit" from the strategy literature.<br />

III. A FRAMEWORK FOR STRATEGIC HYPOTHESIS TESTING<br />

In this section, we construct a set of general hypotheses guided by the literature in strategy <strong>and</strong><br />

strategic performance measurement. We describe how to distinguish among problems with strategy<br />

formulation, strategy implementation, <strong>and</strong> strategic fit.<br />

Managers formulate strategies based on ex-ante expectations about how the strategy will translate<br />

into organizational objectives (e.g., customer satisfaction or profitability). Moreover, managers develop<br />

action plans to implement the strategy <strong>and</strong> detail the internal processes needed to achieve the stated<br />

objectives. Consider the relationship between a performance outcome measure, P O , such as profit <strong>and</strong><br />

strategy input measures, S I , related to the firm's internal processes for achieving its strategic objectives:<br />

P = f( S , ε )<br />

O I P<br />

where ε P represents factors that affect performance other than S I . Managers can evaluate the<br />

effectiveness of internal processes by examining<br />

∂PO<br />

. Problems with the strategy as formulated <strong>and</strong><br />

∂S<br />

I<br />

∂PO<br />

implemented are revealed unambiguously if ≤ 0 .<br />

∂S<br />

4 This suggests the following straightforward<br />

hypothesis, stated in null form, as a starting point for evaluating the performance of a given strategy.<br />

H10: Ceteris Paribus strategy inputs are positively related to financial performance.<br />

I<br />

Figure 1 summarizes this <strong>and</strong> subsequent hypotheses. H10 will be rejected if the input metrics show no<br />

(or a negative) relationship with financial performance. This may be caused by two reasons: (1) the<br />

action plan <strong>and</strong> internal processes chosen to implement the strategy do not result in the achievement of<br />

strategy-specific objectives or (2) the formulated strategy does not deliver expected returns, that is,<br />

achieving the chosen strategic objectives does not result in superior financial performance.<br />

Distinguishing between problems in the strategy formulation (e.g. choice of strategy-specific objectives)<br />

<strong>and</strong> problems with strategy implementation (e.g. choice of action plans to achieve strategy-specific<br />

objectives) would be possible if an intermediate strategy-specific customer outcome metric, S O , were<br />

available. 5 In this case, we have<br />

PO = g( SO, εSO)<br />

S = h( S , ε )<br />

O I SI<br />

where ε SO <strong>and</strong> ε SI represent factors that affect performance other than S O <strong>and</strong> S I , respectively.<br />

Problems with the strategy as formulated <strong>and</strong> implemented would be revealed unambiguously if<br />

∂PO ∂PO ∂SO<br />

= × ≤0<br />

∂S ∂S ∂S<br />

I O I<br />

∂P<br />

. 6 O<br />

This occurs if either: (1) ≤ 0<br />

∂SO<br />

∂SO<br />

∂PO<br />

∂SO<br />

<strong>and</strong> > 0 or (2) > 0 <strong>and</strong> ≤ 0 .<br />

∂S<br />

∂S<br />

∂S<br />

Case 1 is consistent with good implementation but poor formulation of strategy. Input measures (unique<br />

internal processes chosen to implement a strategy) are positively related to customer outcomes, but these<br />

customer outcomes are not positively related to the firm's overall financial performance objectives. The<br />

4 We assume throughout that higher values of Si indicate better performance.<br />

5<br />

The performance outcome PO is distinct from the strategy-specific customer outcome S O . P O represents a high-<br />

level performance objective such as profit. O<br />

S represents a strategy-specific objective such as customer experience<br />

or satisfaction with unique product or service attributes.<br />

6 Note that firms often derive a measure of expected performance. In such cases, the strategy’s performance would<br />

be evaluated relative to this target, rather than relative to zero.<br />

second case is consistent with poor implementation but good formulation of strategy. Input measures are<br />

not positively related to customer outcomes, but the customer outcomes are positively related to the firm's<br />

overall financial performance objectives. In a BSC framework with strategically linked input- <strong>and</strong><br />

output-oriented metrics, this suggests the following hypotheses for evaluating whether observed problems<br />

with a given strategy’s performance is due to poor implementation or poor formulation:<br />

H20: Ceteris Paribus strategy inputs are positively related to strategy-specific customer<br />

outcomes.<br />

H30: Ceteris Paribus strategy-specific customer outcomes are positively related to<br />

financial performance. 7<br />

H20 or H30 could be rejected if the given strategy requires the presence of complementary<br />

intangible assets to succeed. The RBV literature suggests that returns to formulating <strong>and</strong> implementing a<br />

strategy may depend on the level of complementary strategic resources. Much of this literature argues<br />

that specialized complementary resources provide the basis for sustainable competitive advantage (Teece<br />

1986; Tripsas, 1997). Empirical research in this area demonstrates that strategic resources, such as<br />

human capital, interact with strategy inputs <strong>and</strong> strategy outcomes to affect performance (Hitt et. al.<br />

2001). That is, the marginal effects of customer outcomes on financial performance (quality of strategy<br />

formulation) <strong>and</strong> input measures on customer outcomes (quality of strategy implementation) are<br />

determined by whether the level of a complementary strategic resource is below the level necessary for<br />

positive returns to the formulated strategy. We refer to these strategic resources as internal capabilities<br />

<strong>and</strong> focus on manager <strong>and</strong> employee skills. Thus, we have the following hypotheses for evaluating<br />

whether observed problems in strategy formulation <strong>and</strong> strategy implementation are due to poor fit with<br />

internal capabilities:<br />

H40: Ceteris Paribus the marginal impact of increases in strategy inputs on strategyspecific<br />

customer outcomes is positively related to the level of internal capabilities.<br />

7 Our framework could also be used to identify cases where unique internal processes chosen to implement strategy<br />

are negatively related to strategy-specific outcomes <strong>and</strong> strategy-specific outcomes are negatively related to overall<br />

performance objectives. In this case, unique internal processes chosen to implement strategy are positively related<br />

to overall performance objectives, but the detailed analysis would highlight problems of poor implementation <strong>and</strong><br />

poor formulation that make such a strategy unsustainable.<br />

10


H50: Ceteris Paribus the marginal impact of increases in strategy-specific customer<br />

outcomes on financial performance is positively related to the level of internal<br />

capabilities.<br />

Thus far, the hypotheses have focused on identifying problems with strategy formulation,<br />

implementation, <strong>and</strong> fit from the perspective of senior management. It is at this level where strategic<br />

objectives are chosen <strong>and</strong> strategy inputs (unique internal processes) for implementing those objectives<br />

are selected. However, problems of strategic "fit" may also arise if a company's internal capabilities do<br />

not allow it to achieve the desired strategic inputs needed to successfully execute the implementation<br />

plan, suggesting the following straightforward hypothesis.<br />

H60: Ceteris Paribus internal capabilities are positively related to strategy inputs.<br />

IV. RESEARCH SITE<br />

Store24 is a privately held convenience store retailer in New Engl<strong>and</strong>, the 4 th largest in the region.<br />

Its stores, located through Massachusetts, New Hampshire, Rhode Isl<strong>and</strong>, <strong>and</strong> Connecticut, are grouped<br />

into nine geographic divisions, each with its own division manager. Stores are homogenous in many<br />

aspects of their operations including compensation, technology, management structure, <strong>and</strong> product<br />

pricing, but they vary in size, geographic location, market demographics, <strong>and</strong> product mix.<br />

The company’s primary product categories include cigarettes, beverages, snacks, prepared foods,<br />

<strong>and</strong> lottery tickets. Revenues totaled approximately $180 million in fiscal year 1998 (May 1, 1998 to<br />

April 30, 1999). Store24 employed 800 people including 740 store managers <strong>and</strong> crew <strong>and</strong> 60 corporate<br />

level employees. The skills <strong>and</strong> experience of these employees vary widely overall <strong>and</strong> across stores.<br />

Store24 operates in a mature environment with competition from convenience stores, gasoline<br />

retailers, <strong>and</strong> drug stores. Traditionally, convenience store retailing focused on short-term productivity<br />

(e.g., inventory <strong>and</strong> cash control). As the convenience store industry matured <strong>and</strong> competition intensified,<br />

marketing, customer service, <strong>and</strong> br<strong>and</strong> name emerged as differentiating factors. Before FY 1998 <strong>and</strong><br />

after FY 1999, Store24 did not differentiate itself; rather it focused on excelling at traditional service<br />

quality metrics such as physical environment (cleanliness <strong>and</strong> store layout) <strong>and</strong> quality of the customer<br />

experience (fast, friendly service) (Fitzsimmons <strong>and</strong> Fitzsimmons, 2001).<br />

11


During FYs 1998 <strong>and</strong> 1999 (that is from May 1, 1998 to April 30, 2000), Store24 formulated a<br />

strategy aimed at increasing same-store sales <strong>and</strong> margins because growing via new sites was difficult.<br />

“Location is a primary driver of store performance. However, we are stymied on the growth front due to<br />

a lack of acceptable new sites. This has led to a focus on optimizing our existing sites through an<br />

increasing emphasis on store-level marketing <strong>and</strong> operations,” explained Store24’s CFO. To achieve its<br />

goals, Store24 changed its strategy to creating entertaining in-store atmospheres that would differentiate<br />

its stores from those of competitors.<br />

The Differentiation <strong>Strategy</strong><br />

Store24 implemented this new, innovative store-level strategy during the first quarter of FY 1998<br />

(i.e., beginning May 1, 1998). It aimed to differentiate its stores while maintaining performance on<br />

traditional productivity measures. Successful retailers, such as Disney stores, offer “fun <strong>and</strong> interactive”<br />

shopping experiences. Store24’s CEO believed that adopting a similar strategy would improve financial<br />

performance. Store24 provided a fun in-store atmosphere by emphasizing specific themes.<br />

Store-level strategy execution centered on a large display case (i.e., “endcap”) featuring theme-<br />

oriented promotional items <strong>and</strong> store decorations that fostered employee interaction with customers. For<br />

example, during the old movie theme stores featured life-size cutouts of movie stars, endcaps contained<br />

high-margin videos of old movies, <strong>and</strong> old movies became a conversation piece. The themes sought to<br />

attract urban adults between the ages of 14 <strong>and</strong> 29 years, a growing market segment <strong>and</strong> Store24’s target<br />

market. A senior manager explained, “The [Differentiation] strategy was really playing off of the urban,<br />

young adult market. Marketers know that this demographic gets bored easily <strong>and</strong> needs to be stimulated.<br />

We wanted this group to always see new <strong>and</strong> different things in the store.”<br />

In contrast to the basic service quality component, store-managers were accorded autonomy in<br />

implementing the differentiation strategy. That is, although all stores were required to implement the new<br />

strategy, how they implemented or how much they implemented varied across stores. Corporate defined<br />

a theme <strong>and</strong> provided the endcaps, but store employees possessed considerable flexibility in strategy<br />

execution. Thus, manager <strong>and</strong> crew skills were at least as important as theme choice to the strategy’s<br />

12


success. Store24’s controller explained, “Our best managers really took the strategy to heart. The<br />

strategy served as an outlet for manager <strong>and</strong> crew creativity. However, other managers put minimal effort<br />

into this strategy <strong>and</strong> even stocked traditional items such as chips on the endcaps saying they needed the<br />

product space.”<br />

The differentiation strategy, as originally conceived, centered on the physical environment. But<br />

the interaction between store employees <strong>and</strong> customers was crucial to the strategy’s success. Senior<br />

management intended the themes <strong>and</strong> promotions to serve as points of interaction that would help Store24<br />

establish relationships with customers <strong>and</strong> cross-sell high margin products. Explained a senior executive,<br />

“The endcaps <strong>and</strong> displays under the [differentiation strategy] had the dual intention of building a rapport<br />

with customers <strong>and</strong> bumping up the average sales per customer. We felt that store management <strong>and</strong> crew<br />

could use the displays as “ice-breakers” in talking with customers. In addition, the margins on the<br />

promotional items featured under the [differentiation] strategy were typically two to four times the<br />

margins of our traditional products. When customers were browsing or “window shopping” we<br />

encouraged store crew to direct the customer’s attention to these promotional items.” Store24 looked to<br />

its differentiation strategy to attract new customers <strong>and</strong> increase store sales, specifically, sales of higher-<br />

margin, strategy-specific products, <strong>and</strong> thereby boost store profits.<br />

Performance Measurement System<br />

Store24 used a balanced scorecard-based performance measurement system. The company<br />

collected information on a variety of performance measures at various levels of the organization <strong>and</strong> at<br />

various frequencies. Management collected store-level financial performance metrics quarterly.<br />

It monitored store-level customer measures less frequently. Between the 1st <strong>and</strong> 4 th quarters of<br />

FY 1999, an external research firm solicited feedback from customers at 65 stores about Store24, its<br />

product selection, <strong>and</strong> other factors that would persuade them to shop at Store24 more often. Customers<br />

ranked unique attributes related to the differentiation strategy that they found appealing; among these was<br />

“fun place to shop,” “entertaining,” <strong>and</strong> “unexpected.” Additionally, the research firm conducted semi-<br />

annual telephone surveys of self-identified convenience store customers in Store24’s major markets to<br />

13


assess the likelihood of customers shopping at Store24, name recognition of Store24, <strong>and</strong>, for Store24<br />

customers, the quality of merch<strong>and</strong>ise, price, <strong>and</strong> store cleanliness.<br />

Store24 translated the components of its strategy into a set of store-level operating st<strong>and</strong>ards <strong>and</strong><br />

measured store-level conformance to these st<strong>and</strong>ards via walk-through audits conducted twice per quarter.<br />

During these announced visits management evaluated store performance on various dimensions including<br />

in-store image, in-stock position, <strong>and</strong> store appearance. The walk-through audit score quantified the<br />

store-level implementation of Store24’s operating strategy. For FYs 1998 <strong>and</strong> 1999, the st<strong>and</strong>ards<br />

reflected both the differentiation strategy as well as traditional service quality metrics. A store’s<br />

differentiation score referred to a separate measure of conformance to only st<strong>and</strong>ards related to the<br />

differentiation strategy such as actions in terms of themes <strong>and</strong> products that would make Store24 a fun<br />

<strong>and</strong> entertaining place to shop. Store24 also measured conformance to store-level operating st<strong>and</strong>ards<br />

through monthly surprise visits or “mystery shops.” The mystery shop review, which consisted of twenty<br />

high-level questions, helped to ensure the validity of the walk-through audit scores. Scores on the<br />

announced <strong>and</strong> unannounced visits are significantly <strong>and</strong> positively correlated.<br />

Senior <strong>and</strong> division management considered employee skills critical to consistent implementation<br />

of the store-level operating strategy. Accordingly, Store24 measured manager <strong>and</strong> crew skills through bi-<br />

annual evaluations of performance in guest interactions, merch<strong>and</strong>ising, machinery maintenance, store<br />

condition, adherence to policy, loss prevention, <strong>and</strong> problem solving. Store manager <strong>and</strong> crew<br />

compensation was tied to, for example, store-level profit <strong>and</strong> strategy implementation measures. To<br />

encourage implementation of the differentiation strategy specifically, employee rewards were based on<br />

both the differentiation score <strong>and</strong> total walk-through audit score.<br />

As a result of these measures <strong>and</strong> incentives, all stores implemented the new strategy. But,<br />

implementation of the differentiation strategy was not straightforward. Beyond the physical environment<br />

<strong>and</strong> stocking of new products, it required store staff to establish relationships with customers <strong>and</strong> sell<br />

high-margin products. <strong>Implementation</strong> of the strategy varied significantly among stores. Even when<br />

stores implemented the strategy well, there was variation in how customers experienced the new strategy.<br />

14


There was also significant variation across stores in profitability. These variations allow us to draw<br />

conclusions about both strategy formulation <strong>and</strong> implementation.<br />

We analyze Store24’s BSC data, including the walk-through audit scores, financial performance<br />

measures, <strong>and</strong> employee metrics, to learn more about the hypothesized causal links around the strategy. 8<br />

<strong>Strategy</strong> Change<br />

Store24 incorporated the differentiation component during FYs 1998 <strong>and</strong> 1999. During this time,<br />

management monitored the scorecard. Store-level execution of operating st<strong>and</strong>ards (strategy-inputs)<br />

declined <strong>and</strong> then gradually increased over this period (Figure 2), <strong>and</strong> the strategy-specific customer<br />

outcome measure followed the same pattern. In each quarter of FY 1999 Store24 posted a higher profit<br />

than in the corresponding quarter of FY 1998 (Figure2). Store24 management, however, could not<br />

attribute the strong financial performance to the new strategy as growth in profits closely tracked industry<br />

averages. In FY 2000, based on negative customer feedback, Store24 concluded that the differentiation<br />

strategy had failed <strong>and</strong> refocused its strategy on traditional service quality activities. 9 See Figure 3 for a<br />

timeline of events related to Store24’s strategy change. Based only on trends in the balanced scorecard<br />

metrics, it was difficult for management to definitively disentangle problems with strategy formulation<br />

from those with strategy implementation. That is, it wasn’t easy to pinpoint why the strategy failed.<br />

Store24 senior management also identified potential problems related to the “fit” of the<br />

differentiation strategy with the existing level of employee capabilities at its stores. Senior management<br />

believed successful store-level implementation of this strategy required performance in complementary,<br />

difficult to measure activities. To leverage the environment into financial performance, skilled employees<br />

needed to establish customer relationships. Senior management believed that high skill levels enhanced<br />

<strong>and</strong> low skill levels limited, the relationship between implementation of the differentiation strategy <strong>and</strong><br />

store performance. Explained Store24’s CFO, “Managers <strong>and</strong> crew that were already skilled in our core<br />

[efficiency based] strategy <strong>and</strong> other basic store operations such as cash, labor, <strong>and</strong> inventory control,<br />

8 We omit the mystery shop scores due to their correlation with walk-through audit scores <strong>and</strong> data availability. We<br />

cannot disaggregate mystery shop scores into basic service quality <strong>and</strong> differentiation strategy implementation<br />

measures.<br />

9 Store24 received negative feedback from in-store comment cards, telephone surveys <strong>and</strong> focus groups.<br />

15


were able to devote considerably more time to implementing the [differentiation] strategy <strong>and</strong> to tailor<br />

this strategy based on knowledge of their customers. These skills made it easier to build the<br />

[differentiation] strategy on top of the basics.” The success of local strategy implementation relied on<br />

manager <strong>and</strong> crew interactions with customers <strong>and</strong> local market knowledge. Absent these complementary<br />

activities, differentiation implementation might not translate into improved store performance, <strong>and</strong> might,<br />

in fact, adversely affect performance, particularly on the productivity dimension.<br />

<strong>Using</strong> the information learned by management over time about problems with the strategy as a<br />

benchmark, we seek to examine the insights derived from systematic analysis of the scorecard measures.<br />

V. EMPIRICAL RESEARCH DESIGN<br />

Our sample consists of financial, non-financial <strong>and</strong> customer performance measures for 65 stores<br />

during fiscal years 1998 <strong>and</strong> 1999 (i.e., during implementation of the differentiation strategy). To obtain<br />

scores on store-level differentiation, we disaggregate the walk-through audit scores into their constituent<br />

components. We have data for store-level implementation of the differentiation strategy for the fourth<br />

quarter of FY 1998 <strong>and</strong> the second <strong>and</strong> third quarters of FY 1999.<br />

We supplement Store24’s balanced scorecard data with information on store competition <strong>and</strong><br />

demographics gathered during the same time period. To gain familiarity with the business environment<br />

we interviewed Store24 senior management <strong>and</strong> reviewed company documents about the measurement<br />

system <strong>and</strong> strategic learning process. Finally, we interviewed five store managers about store-level<br />

execution of the differentiation strategy.<br />

Empirical Variables<br />

Financial Performance<br />

To improve its financial performance, Store24 can: i) increase customers; ii) increase spending<br />

per customer; or iii) increase the efficiency <strong>and</strong> effectiveness of store personnel (decrease costs).<br />

Operating profit (Profit) summarizes these categories at the store level; it is defined as revenues (Sales)<br />

from general merch<strong>and</strong>ise, lottery tickets, money orders, <strong>and</strong> phone cards less cost-of-goods sold, utilities<br />

expense, <strong>and</strong> labor expense. This measure reflects the financial components that Store24 believes store-<br />

16


level management can influence <strong>and</strong> is the primary measure used by management to evaluate overall store<br />

financial performance. We measure Profit as annual operating profit during FY 1999. This is the period<br />

we are able to match with available strategy input measures, strategy outcome measures, <strong>and</strong> measures of<br />

employee capabilities. FY 1999 is the second year of Store24's differentiation strategy, allowing enough<br />

time for any start-up problems in implementation to be worked out. In all analyses, we scale Profit by<br />

square feet of store selling space.<br />

Non-financial Performance Measures<br />

Measure of <strong>Strategy</strong> Inputs. Store-level measures of strategy inputs capture store-level activities that<br />

management believes drive strategy success. Senior <strong>and</strong> mid-level management measure performance by<br />

conducting walk-through audits twice per quarter. Management awards points based on compliance with<br />

78 operating st<strong>and</strong>ards related to in-store image, in-stock position, merch<strong>and</strong>ising <strong>and</strong> marketing<br />

management, <strong>and</strong> facilities appearance. A percentage score is calculated by dividing total awarded points<br />

by total potential points. 10<br />

We disaggregate stores’ total operational audit scores into scores that reflect the store’s<br />

compliance with operating st<strong>and</strong>ards (strategy input measures) for the differentiation strategy. 11<br />

Input_Diff reflects a store’s percentage score on operating st<strong>and</strong>ards related to differentiation; it reflects<br />

how well each store executed this strategy or the quality of the “inputs”. We use the strategy input<br />

measure taken at the beginning of FY 1999 in all our empirical analyses (Input_Diff).<br />

Measure of Basic Service Quality. During the walk-through audit, Store24 management also measures<br />

basic service quality items such as in-store image, fast service, <strong>and</strong> in-stock position. BSQ is the average<br />

percentage score on operating st<strong>and</strong>ards related to basic service quality taken over the same period as our<br />

measure of strategy inputs.<br />

10 Mystery shop scores are positively <strong>and</strong> significantly correlated with walk-through audit scores <strong>and</strong> cannot be<br />

disaggregated. Adding mystery shop scores to the analyses does not change the results.<br />

11 Due to extra credit points for strong implementation of Differentiation, a store’s score on Input_Diff can reach<br />

135%. Employees were compensated based on a separate measure of this strategy normalized by total available<br />

points. Thus, they were induced to invest in this implementation.<br />

17


Measure of <strong>Strategy</strong>-Specific Customer Outcomes. A third-party research firm conducted in-store<br />

customer interviews at a subset of stores throughout FY 1999. 12 Customers rated the attributes they<br />

“liked most about this particular Store24,” including whether Store24 was “entertaining,” “a fun place to<br />

shop,” <strong>and</strong> “unexpected.” We collect the metrics specific to the differentiation strategy; these metrics<br />

comprise a reliable set as evidenced by a Cronbach’s coefficient alpha of 0.9596. Each attribute is<br />

measured as the proportion of surveyed customers who stated that they liked this characteristic about a<br />

particular store; Outcome_Diff is the average of these measures. Outcome_Diff reflects whether<br />

customers observe <strong>and</strong> value the new strategy; it represents a strategy-specific customer outcome measure<br />

resulting from implementation of the differentiation strategy (strategy input measures).<br />

Employee Capabilities. Store24 relies on its employees to execute strategy at the point of customer<br />

contact. Thus, we take measures of manager <strong>and</strong> crew skills as our primary measures of the firm’s<br />

strategic resources. Store24 evaluates its managers during the 2 nd <strong>and</strong> 4 th quarters of each fiscal year.<br />

Managers are rated, on a five-point scale, on many dimensions including ability to retain, train, <strong>and</strong><br />

interact with crew; customer service; merch<strong>and</strong>ising; time <strong>and</strong> labor management; maintaining store<br />

safety; <strong>and</strong> technology use. A store manager’s skill rating (MgrSkill) is the average score across all<br />

dimensions. Crew skills are rated on a five-point scale along similar dimensions; all non-management<br />

employee scores are averaged to devise a store’s crew skill rating (CrewSkill). In all subsequent<br />

empirical tests, we use the skill metrics taken in the beginning of FY 1999. 13<br />

Were Store24’s senior management simply to infer skill ratings from actual store performance, a<br />

store’s manager <strong>and</strong> crew skills ratings would reflect store performance rather than exogenous skill levels.<br />

As shown in Table 2, neither manager nor crew skills exhibit significant correlations with Profit.. Thus,<br />

on average, senior executives do not provide higher skill ratings to employees in better performing stores.<br />

Data on individual employee skill ratings for a sample of 20 stores reveals variation in skill ratings across<br />

12<br />

Data was collected for approximately 15-20 stores per quarter.<br />

13<br />

Our results are invariant to the use of average skills throughout FY 1999 rather than taking the skill metrics at the<br />

beginning of FY 1999.<br />

18


individual employees within a particular store, reflecting senior management’s desire to identify<br />

individual skills rather than infer skill-level from store performance.<br />

Control variables. Store24 collects demographic information for the half-mile radius around each store.<br />

Many of these demographics relate to population <strong>and</strong> foot traffic in the trading area of a given store <strong>and</strong><br />

are highly correlated. Because many of these variables are correlated we use factor analysis to identify<br />

the underlying constructs <strong>and</strong> find one population factor with an eigenvalue greater than one. Population<br />

represents daily activity around the store location. It comprises primarily the student population (pre-high<br />

school, high school, <strong>and</strong> college), pedestrian count rating, <strong>and</strong> population density. Income is an estimate<br />

of the median level of annual disposable income available to a family for grocery <strong>and</strong> convenience store<br />

purchases in the surrounding area.which Store24 obtains from a third-party research firm. Because we<br />

expect high income <strong>and</strong>/or large population areas to offer more sales potential, these variables should<br />

relate positively to financial performance. Finally, having more competing stores in the area is expected<br />

to be associated with lower financial performance. To control for this effect, we include Competition<br />

which reflects the number of competing stores within a half-mile radius of each store.<br />

We also control for unobservable location characteristics by including rent per square foot (Rent).<br />

Store24 pays a premium to rent facilities in locations with, for example, high visibility. Cross-sectional<br />

differences in Rent should capture store location differences which we do not directly control for in our<br />

analyses. Finally, we include a measure of store size (SQFT), measured as square feet of retail selling<br />

space, <strong>and</strong> a variable that indicates whether a store is open 24 hours per day (24Hours).<br />

Methodology<br />

We test the baseline hypothesis, H1, by estimating the following equation:<br />

t<br />

PROFITi = α + α Input _ Diff + α MgrSkill 0 1 i 2 i + α CrewSkill + α BSQ + α Competition<br />

3 i 4 i 5<br />

i<br />

+ α Population + α Income + α 24 Hours + α SquareFeet + α Rent + ε<br />

6 i 7 i 8 i 9 i 10 i i<br />

Where PROFITi denotes operating profit for store i during FY 1999. We estimate this equation using<br />

OLS on a cross-sectional sample of 65 stores. To reduce collinearity due to the inclusion of the<br />

(1)<br />

19


interaction terms <strong>and</strong> to maintain interpretability of the coefficients, we mean center the interaction<br />

variables prior to estimation (Aiken <strong>and</strong> West 1991).<br />

If the strategy-input measure leads to improved financial performance, we expect α1 to be positive<br />

<strong>and</strong> significant. Finding no (a negative) relationship implies that improved strategy implementation is not<br />

(negatively) associated with improved performance, signaling problems with strategy formulation,<br />

strategy implementation or strategy fit.<br />

Consistent with the framework outlined in section III, we test for problems in strategy<br />

implementation (H2), strategy formulation (H3), <strong>and</strong> strategy fit (H4, H5, <strong>and</strong> H6) by using OLS to<br />

estimate the following equations.<br />

PROFITi = γ0 + γ1Outcome _Diffi + γ2Outcome _Diffi× MgrSkilli + γ3Outcome<br />

Equation (2) is analogous to equation (1) where the outcome measure replaces Store24’s internal<br />

input measure 14 . Equation (3) tests the relationship between the outcome measure <strong>and</strong> Store24’s input<br />

measure. 15 A positive correlation, β1, indicates relatively good implementation of the differentiation<br />

strategy because the outcome measure correlates with the input metrics. β1>0, γ1 ≤0 would provide<br />

evidence in favor of H20 <strong>and</strong> against H30 implying a good implementation of a bad strategy.<br />

Conformance to operating st<strong>and</strong>ards (strategy inputs) leads to the desired strategy-specific customer<br />

14 In untabulated tests, we estimate equation 2 separately for stores where Outcome_Diff was measured during the<br />

first 6-months <strong>and</strong> second 6-months of FY 1999 respectively. In these tests, for stores measured in the first (second)<br />

6-months, we measure manager <strong>and</strong> crew skills as the average of skills as measured during the end of the fourth<br />

quarter of FY 1998 (second quarter of FY 1999) <strong>and</strong> the second quarter of FY 1999 (fourth quarter of FY 1999).<br />

The results from estimation of equation 2 on each of these sub-samples are substantively similar to those reported in<br />

Table 5 on the full sample of stores. These results mitigate the potential that the findings in our paper are due to any<br />

mismatch in performance measurement periods within Store24.<br />

15 Note that we do not include demographic <strong>and</strong> other store location characteristics as controls in Equation 3. There<br />

is no a priori reason to believe that strategy-specific outcomes should be driven by these factors. However, we have<br />

estimated Equation 3 using the same controls as in Equations 1 <strong>and</strong> 2 <strong>and</strong> results are substantively similar.<br />

outcome (customers view stores as “entertaining"), but the strategy-specific customer outcome does not<br />

translate into improved store financial performance. β1≤0, γ 1 >0 would provide evidence against H20 <strong>and</strong><br />

in favor of H30; it is consistent with bad implementation of a good strategy. <strong>Strategy</strong>-specific customer<br />

outcomes (more entertaining stores) are associated with higher financial performance; however the<br />

strategy input measures do not lead to higher levels of strategy-specific customer outcomes.<br />

To test the complementary impact of Store24’s strategic capabilities on the relationships between<br />

input, outcome <strong>and</strong> financial performance measures, we rely on the interaction terms,<br />

2Outcome _ Diffi MgrSkilli<br />

λ × <strong>and</strong> 3 _ i i<br />

2Input _ Diffi MgrSkilli<br />

β × <strong>and</strong> 3 _ i i<br />

λ Outcome Diff × CrewSkill , for strategy formulation tests <strong>and</strong><br />

β Input Diff × CrewSkill for strategy implementation tests.<br />

Significant coefficients on these variables indicate that the level of internal capabilities impacts the<br />

relationships among input measures, outcome measures <strong>and</strong> financial performance (H4 <strong>and</strong> H5).<br />

Finally, we use equation (4) to investigate the final part of the "strategic fit" hypothesis (H6) by<br />

examining the relationship between performance on the input metric (Input_Diff) <strong>and</strong> the level of internal<br />

capabilities (MgrSkill, CrewSkill). We include MgrSkill, <strong>and</strong> CrewSkill in equations (2) <strong>and</strong> (3) to<br />

account for any main effects of employee capabilities on store financial performance. 16<br />

Although scaling by store size (Square Feet) alleviates concerns with heteroskedasticity, we<br />

calculate p-values based on both OLS st<strong>and</strong>ard errors <strong>and</strong> Mackinnon <strong>and</strong> White’s (1985)<br />

heteroskedasticity consistent “HC3” st<strong>and</strong>ard errors with no substantive differences in results. 17<br />

RESULTS<br />

Descriptive Statistics<br />

Table 1 provides descriptive statistics <strong>and</strong> Table 2 presents the correlation matrix for the sample<br />

of 65 stores. Note that the stores exhibit wide cross-sectional variability in both Store24’s input measure<br />

16 Managers with high skills may, for example, more effectively manage labor <strong>and</strong> inventory costs which would<br />

have a direct effect on store-level financial performance.<br />

17 White’s test for heteroskedasticity is not as reliable in small samples (Mackinnon <strong>and</strong> White 1985, Long <strong>and</strong><br />

Ervin 2000). Long <strong>and</strong> Ervin (1997) suggest using the HC3 estimator for st<strong>and</strong>ard errors when heteroskedasticity is<br />

suspected. Although we have no a priori reason to suspect heteroskedasticity, we check p-values based on HC3<br />

estimators for robustness (untabulated).<br />

(Input_Diff) <strong>and</strong> outcome measure (Outcome_Diff). The univariate correlations suggest that<br />

Outcome_Diff is negatively related to Profit. Additionally, the outcome measure is significantly<br />

positively related to Store24’s input measure (Input_Diff). Together, this provides preliminary evidence<br />

that the differentiation strategy was well implemented, as Store24’s view of good implementation<br />

corresponds to the customer outcome, but possibly poorly formulated due to the negative relation of the<br />

customer outcome with financial performance. Since stores vary on other factors that might affect<br />

financial performance (e.g., location <strong>and</strong> skills) we refrain from making conclusions based on these<br />

univariate tests. Competition, Population, Income, Sqft <strong>and</strong> Rent all exhibit significant correlations with<br />

Profit. Thus, these seem to be powerful controls for unobserved location characteristics that might affect<br />

store performance.<br />

Tests of H1 (Identifying Problems with <strong>Strategy</strong> <strong>Formulation</strong> <strong>and</strong>/or <strong>Implementation</strong>)<br />

Table 3 reports the results of estimating the relationship between Profit <strong>and</strong> Store24’s assessment<br />

of stores’ internal conformance with strategic operating st<strong>and</strong>ards. On average, the input metric,<br />

Input_Diff, is not associated with Profit. This suggests that store-level effort to implement the new<br />

strategy was not translating into store-level profits. Manager skills significantly <strong>and</strong> positively relate to<br />

profit as does population in the surrounding area; competition is negatively related to profit. Rent per<br />

square foot is positively related to profit suggesting that higher rents are proxying for characteristics<br />

associated with better store locations.<br />

These results highlight that the hypothesized link between internal implementation of the action<br />

plans related to the new strategy <strong>and</strong> financial performance does not exist. However, it is unclear whether<br />

the strategy is poorly formulated or poorly implemented.<br />

Tests of H2 <strong>and</strong> H3 (Distinguishing between Problems of <strong>Formulation</strong> vs. <strong>Implementation</strong>)<br />

Table 4 contains results from estimation of equation (3). On average, Store24’s input metric<br />

(Input_Diff) positively relates to the outcome measure (p


innovative <strong>and</strong> entertaining (strategy-specific customer outcome). Estimation of equation (2) yields Panel<br />

A of Table 5. On average, the outcome measure of the differentiation strategy implementation is<br />

negatively related to Profit (p


We further examine the interaction between crew <strong>and</strong> the outcome measure using post-hoc probing as<br />

suggested by Aiken <strong>and</strong> West (1991). 20 Panel B of Table 5 illustrates the estimated relationship between<br />

the outcome measure (Outcome_Diff ) <strong>and</strong> financial performance (Profit), conditional on high (1 point<br />

above the mean rating), mean, <strong>and</strong> low (1 point below the mean rating) crew skills, respectively. We<br />

compute the st<strong>and</strong>ard errors for each estimated relationship in Panel A of Table 5 conditional on the level<br />

of crew skills <strong>and</strong> adjust t-statistics accordingly prior to inference.<br />

The outcome measure negatively impacts Profit in stores with low <strong>and</strong> average skills. However,<br />

these negative impacts seem to be mitigated in stores with high crew skills where there is a positive<br />

relationship between the outcome measure <strong>and</strong> Profit. Overall, the results suggest problems with the fit<br />

of the differentiation strategy with Store24’s employee capabilities. Crew skills determine the magnitude<br />

of the relationship between strategy outcomes <strong>and</strong> financial performance, but the relationship is only<br />

greater than zero for high levels of crew skills. 21<br />

Results of H6 (Identifying Fit at the Operational Level)<br />

The results of tests of the drivers of the input metrics are presented in Table 6. On average, crew<br />

skills are not significantly related to strategy execution at the store-level; manager skills are positively <strong>and</strong><br />

significantly related to store-level strategy execution (Input_Diff) (p


firm-specific non-financial metrics <strong>and</strong> accounting returns may be informative about (1) the firm’s<br />

strategy formulation, (2) its strategy implementation, or (3) the strategy’s fit with internal capabilities.<br />

We provide some of the first field-based empirical evidence on the potential for a set of strategically<br />

linked performance measures to distinguish between these three alternatives.<br />

Companies develop links in non-financial performance measurement systems based on ex ante<br />

expectations (Ittner <strong>and</strong> Larcker 1998). Our findings indicate that non-financial <strong>and</strong> financial measures<br />

<strong>and</strong> the hypothesized links between them can be used more extensively for continuous hypothesis testing<br />

ex post. Building on prior research illustrating the use of balanced scorecards data to communicate<br />

strategy (Selto <strong>and</strong> Malina 2001; Banker et. al. 2004), we use Store24’s balanced scorecard data to study<br />

how the system can be used to test strategy performance. Our findings suggest that ongoing tests of these<br />

relationships are important to ensure that hypothesized links are valid. Such investigation can potentially<br />

reveal specific aspects of a strategy’s merits as well as its shortcomings; it can help distinguish between<br />

strategic problems related to formulation, implementation, or fit of the strategy with the firm’s internal<br />

capabilities. If a company consistently applies its scorecard across multiple units, these tests can be<br />

performed at an early stage, prior to collecting an extensive longitudinal sample.<br />

The results in this paper are subject to the caveat that the field-based nature of our research limits<br />

the generalizability of our findings. However, the unique nature of any firm’s strategy dictates that the<br />

performance measures <strong>and</strong> links between these measures, articulated in the firm’s business model, are<br />

likely to be firm-specific. Future research should provide additional evidence from other settings of the<br />

extent to which business model-based performance measurement systems capture information useful for<br />

monitoring strategic progress. We recognize that there is a strong interrelationship between the concepts<br />

of strategy-formulation, strategy-implementation, <strong>and</strong> fit. We define our tests of strategy-formulation as<br />

analyzing whether, given the resources available to Store24, their choice of strategy was sound. Similarly,<br />

our tests of implementation refer to the efficacy of Store24's unique internal processes in achieving its<br />

strategic objectives given its available resources. Our point is not to belabor the distinction between<br />

formulation, implementation, <strong>and</strong> fit, but rather to identify a method that can systematically test how well<br />

25


different drivers of performance are working to achieve strategic objectives <strong>and</strong> superior financial<br />

performance.<br />
