Schriber, J. B., & Gutek, B. A. (1987). Some dimensions of work: Measurement of an<br />

underly<strong>in</strong>g aspect of organizational culture. Journal of Applied Psychology, 72(4), 642-650.<br />

This study exam<strong>in</strong>es the existence of temporal dimension norms <strong>in</strong> organizational culture <strong>and</strong><br />

developed an <strong>in</strong>strument to measure the dimensions as a means to study cross-organizational <strong>and</strong><br />

<strong>in</strong>tra-organizational comparisons. The authors contend that norms of time can be viewed as<br />

characteristics of culture such tat differences among cultures should lead to differences among<br />

views <strong>and</strong> assumptions about time (e.g., do meet<strong>in</strong>gs start on time, is the boss always late, are<br />

employees prompt, are deadl<strong>in</strong>es adhered to, etc.). Norms can prescribe sequential rigidity <strong>and</strong><br />

facilitate conformity. Rigidity <strong>and</strong> conformity to temporal dimensions provide necessary<br />

behavioral control when complex, multiple goals can only be atta<strong>in</strong>ed through coord<strong>in</strong>ated<br />

activity. The temporal aspects of norms guide behavior to <strong>in</strong>crease <strong>in</strong>dividual rewards <strong>and</strong><br />

decrease costs associated with <strong>in</strong>teractions.<br />

The authors developed a Likert scale of 56 items describ<strong>in</strong>g time related behaviors, situations<br />

<strong>and</strong> customs regard<strong>in</strong>g the allocation of time, rout<strong>in</strong>e, <strong>and</strong> coord<strong>in</strong>ation, among others, to<br />

measure workers’ perceptions of 15 separate temporal dimensions or norms. The analysis<br />

extracted 13 usable scales: Time boundaries between work <strong>and</strong> non work, sequenc<strong>in</strong>g of tasks,<br />

punctuality, allocation, awareness, synchronization <strong>and</strong> coord<strong>in</strong>ation, variety versus rout<strong>in</strong>e,<br />

<strong>in</strong>tra-organizational time boundaries, future orientation, schedules <strong>and</strong> deadl<strong>in</strong>es, work pace,<br />

autonomy of time use, <strong>and</strong> quality versus speed. Two hypothesized scales regard<strong>in</strong>g buffer<strong>in</strong>g<br />

did not emerge as factors. The application of these scales can result <strong>in</strong> rich descriptions of<br />

organizational or departmental cultures <strong>and</strong> can establish a basis for comparison between<br />

organizations or subunits (e.g., homogeneity or heterogeneity, variance among hierarchies,<br />

importance of punctuality, disparity between organizational norms <strong>and</strong> personal norms as a<br />

predictor of withdrawal behavior or career success, morale, etc.). These scales may also be<br />

employed as part of a planned change effort.<br />

Sheffield. (1981). Organization climate. In I. Cook (Ed.), The experience of work (pp. 219-<br />

225). San Diego, CA: Academic Press.<br />

This book chapter provides a very concise outl<strong>in</strong>e of 26 organizational climate measurements.<br />

The author describes the history <strong>and</strong> development of each measure. The various components of<br />

organizational climate that are assessed by each measure are described. Areas <strong>in</strong> which each<br />

measure has been applied with<strong>in</strong> <strong>in</strong>dustry is discussed. Where available, a discussion of the<br />

validity of the <strong>in</strong>dividual measures is also provided.<br />
