SMEF ® 2012
25-26 June 2012 PROGRAM
Why should you attend?
Istituto Internazionale di Ricerca, part
of Informa Plc, and DPO (Data
Processing Organisation), leader
company in software measurement,
in cooperation with Simple Function
Point Association (SiFPA), are
delighted to announce the 9th
Software Measurement European
Forum. The 2012 event offers a
program designed to illustrate the
best practices, recommendations,
tools, techniques and implementation
processes of software measurement
in order to optimize the processes of
planning, negotiation, execution and
control of software contracts.
Using software metrics in contracts is
not only a subject for technicians: all
the parts that are involved in the
procurement process should be
aware of the opportunity and risks of
using it and on the more effective
ways of adoption. This year’s event
will focus on this area resulting as an
in depth analysis of methods,
models, experiences.
Program
Software Contract Management
by metrics: a methodological
framework
Roberto Meli (DPO Italy)
This presentation will introduce a conceptual
and operational framework for the application
of the software measurement discipline
within the context of a contractual relationship
between customer and supplier. Any
given contractual agreement regarding software
acquisition requires a specific implementation
of a measurement model. A
Contractual Measurement Model is a set of
answers to the following questions:
• Why to measure? (business goals)
• What to measure? (nature of an ad-hoc
software supply, scope of work, on going
change request, cancelled activities,
reuse and replication)
• How to measure? (contractual scheme,
measurement method, process and
tools)
• When to measure? (during the contract
life cycle)
• Who will measure? (role and
responsibilities)
Parametrics in contracts is also
beneficial for suppliers
Ton Dekkers (Galorath International
Netherlands / UK)
In a tender the supplier has to commit to
the rules defined by the customer. In this
case the customer wanted a all-inclusive
price per function point for a given project
size. The supplier’s experience with this
type of tender was very limited. This case
describes the approach and the challenges
to get in the end to a successful project
tender.
• Validating project size with (NESMA)
Function Point Analysis
• Validation and Verification performance
based on ISBSG data and SEER for
Software
• Convince supplier management on a
competitive bid based on parametric
models
When Metrics Mean Business
Maurizio Aguiar (TI Metricas Brasil)
Measurement specialists often wonder why
so many Brazilian organizations use functional
size as a basis for software development
contracts. Brazilian organizations
from several industries such as banks, airlines,
telecommunication companies, and
government agencies use function points
as a basis for software development contracts.
The Brazilian government has
issued a directive known as “IN04” instructing
all government agencies to use
metrics - usually function points - in software
development contracts to define productivities,
prices, and quality criteria. In
those organizations most software development
services are billed based on the
functional size. Even support activities
such as measurement and testing have
been known to be billed based on function
points. Function point analysis is now an
indispensable part of the business cycle
and a daily activity in many organizations.
This presentation discusses the business
drivers that have made Brazil the number
one user of function points in the world, as
well as the business processes involved.
• Why and how Brazilian organizations use
functional sizing in software
development contracts
• How the functional size supports
contract objectives for both the acquirer
and supplier
• Technical considerations related to the
use of function points in contracts
• Benefits and challenges to be aware of
when using function points in contracts
Beyond perception: Peeking over
the wall to get real control...
Eric van der Vliet, Paul Siemons
Eric van der Vliet (Logica Netherlands)
Management in an organisation have the
role to control their environment with the
intention to achieve their objectives.
Objectives for managers are derived from
organisation level objectives and often defined
by means of KPI’s. The focus of KPI’s
is mainly on financial, productivity, quality
or elapsed time aspects. By all means will
these aspects influence the contracts, therefore
it’s relevant whether the information
the decisions are based on is perception or
reality. To reduce the gap between perception
and reality the IMD-Model has been
defined.
The IMD-Model offers:
• Validating information: perception or
reality
• Support of management decisions: to
tender or not to tender
• Model based control on information
provided by a measurement system
Through the Looking Glass:
What does a Tender Document
actually tell you?
P. Morrow, F.G. Wilkie, I.R. McChesney,
C. Tuxworth
George Wilkie (School of Computing &
Mathematics, University of Ulster
Northern Ireland - UK)
For fixed-price contracts, the most important
decision to make in a software development
project is whether or not to proceed
in the first place. Consequently, in a
project tender situation the tender (or bid)
estimate is crucial in informing this decision.
The goal of this study is to determine
what can be discerned from what the bid
document does tell you, in order to identify
what it does not tell you
• Q1 - Can a detailed assessment of the
profile of required functionality at two
distinct stages in the project lifecycle
provide a validation of the adequacy of
requirements documentation at the bid
stage of a project.
• Q2 - Do overall indicators of potential
future growth exist in bid
documentation?
• The (Functional) Size Metric used is
(NESMA) Function Points
Successful software projects -
how to limit the risk of failures!
Harold van Heeringen (Sogeti
Netherlands)
This paper focuses on selecting a single
supplier for the development of a custommade
software realisation project, while
keeping in mind that the project should be
successful! Half of the project success is
already determined before the start of the
project, agreeing on the right contract in the
sourcing phase.
Following items will be addressed:
• The questions you should ask the
supplier to answer in their proposal
• Why it is important to select a realistic
proposal, not just the cheapest one
• How to assess the reality value of the
proposals of the different suppliers
Which KPI’s should be defined to make the
contract work
How to state a fair unitary cost for
FP in a tender context
Roberto Meli (DPO Italy)
There are two main paths to state the base

02.83847.262

unitary cost per FP in a Request for Proposal
or a Public Tender. The first one is to rely on
previous similar assigned contracts and
their unitary prices adopting averages or
min-max values (market approach). The
second one is to build a specific unitary
price considering expected average productivity,
adjustment factors, resources mix, unitary
human resource costs, life cycle phases
and distribution of effort and roles (constructive
approach). The same approaches
may be used by the supplier in the offering
phase. The second approach is generally
more adequate since it allows to purify the
process from the usual distortions due to
the “offer to win” approach associated to
the expectation of absence of control in contract
execution. This presentation will discuss
these aspects giving a detailed proposal
for the constructive approach but also an
overview of the market approach with unitary
prices in different countries.
• Unitary price construction
• Avoid “offer to win” distortions
• Keep contract in control after assigning it
The meaning of software
measurement in a contractual
relationship
Marco Gentili (Italy)
Pierfranco Gennai (DPO Italy)
Functional Measurement was developed
aseptically in the research field of Sw
Engineering. When it is used in a contractual
context, in order to manage the
customer/supplier relationship, it is associated
with a number of degenerative nonacademic
interpretations that can produce
real diseases, both during the procurement
process of software development services,
and in the execution phase of the corresponding
contracts. For this reason DigitPA
(formerly CNIPA) decided to treat the functional
measure issue in its “Guidelines on
the quality of ICT assets and services for the
establishment and governance of ICT contracts
in Public Administration”, without forgetting
the need for non-functional measurements
too.
• The easy way to escape: I am not able to
make a “turn key” tender, I do not make
Feasibility Study, I do purchase “by
metrics”, will I be able to use the
balance?
• The mith of FP unitary cost: FP is not a
currency.
• Pseudo estimation: backfiring from costs
• Why considering only Software
Functionalities?
• A missing opportunity (until now):
measuring to manage, knowing to
control, where is the Public
Administration Projects Repository?
A practical approach to validate
actual functional size measures in
a contract
Marco Arzilli, Franco Perna (DPO Italy)
The customer verification of functional size
measures provided by the supplier in the
acceptance phase is a critical activity for the
correctness of contract execution. A lack of
control, both in depth and in scope, can lead
to relevant deviations of the unitary price
accepted in the bid assignment process,
with potential consequences in terms of
unfairness or, in some cases, illegality. In
the presentation we’ll show an efficient and
rigorous approach to validate supplier’s
functional size measures. The approach is
rigorous, since it defines clear and unambiguous
game roles and efficient, in order to
spend the right effort to achieve the right
confidence about suppliers functional size
measurement capabilities. The approach
consists in an incremental sampling technique,
that allows the customer to adjust the
validation effort on the quality level of size
measures provided by the supplier, detected
by the gap among these measures and the
ones checked and validated on a sampling
base. The approach provides also a simple
classification of main causes for this measure’s
deviation, useful to improve both the
measurement and the validation process.
• How to satisfy compliance with
contractual prices
• Validating supplier functional size
measures: why, when and how
• Adopting an efficient validation process is
possible: a practical guide to do this
Software Comprehensive Count
with Quality Indicators (SCCQI)
Jasveer Singh (EUSFP Belgium)
As software size measurement is one of the
most important activities in the software
development lifecycle, the methodology
used for estimating the size should be able
to measure the size comprehensively. That
means that all the software constituents
should be considered for measuring the size
and a proper translation of the measured
size to the effort estimate should be possible.
Software Comprehensive Count with
Quality Indicators (SCCQI) is a methodology
that offers an elaborate and comprehensive
measurement of size, a more realistic effort
estimate (as a result of using 26 extensive
measures of counting) and important and
valuable Key Software Indicators (KSI’s).
AGENDA
The realistic estimate and the KSI’s are very
useful in:
• the bid process (supplier)
• the validation process (customer)
• defining controllable delivery criteria in
contracts
Key Performance Indicators for
ICT Services
Thomas Fehlmann (Euro Project Office
AG, Zurich, Switzerland)
Services related to Information and
Communication Technology (ICT) play a
major role for an organisation's commercial
success and are highly predictive for its prestige
with employees, customers and in
public opinion, and thus for future business.
Despite their strategic importance, ICT services
are often outsourced and contracted
to service providers.Organisations need
early indicators for trends affecting ICT services,
since loss of employees and of customers
invariably ends with loss of market
share and profit. Such indicators can be
used to determine on variable compensation
and incentives for quality service.Functional
size and defect density play a major role;
however, the worst kind of defects in ICT services
is missing market expectations or not
understanding new market requirements
when doing business over the internet and
supported by ICT. How should such defects
be handled in contracts? This paper gives an
overview about state of the art in social
media times and proposes a comprehensive
set of Key Performance Indicators that
should help organisations contracting reliable
ICT services.
The program is under
continuous development.
