Workshop Proposal: PIFs for Projects (“PifPro’13”)

This Workshop Proposal is a continuation of the successful workshop in Assisi October 2012

Measuring Performance Impact Factors for ICT Projects

ICT Projects have a bad reputation: they often exceed budget or change scope. It holds especially when writing new software is involved; however, integration of new services, sizing maintenance or ICT portfolio projects is also affected. Project management is needed but without proper estimation methods and tools it is limited to managing the budget overrun. This is a serious blocker, since ICT should be the major motor for economic growth. Work breakdown structure fails because it is part of the project to find out what work is needed; expert estimation fails because experts cannot remember previous decisions and their estimates suffer from important variations. Without proper budgeting, ICT projects carry enormous risks for the financial stability of the organization sponsoring the ICT project.

There have been other approaches to estimation, especially based on benchmarking within or across organizations and industries. The question then arise which parameters to select for comparing different projects. Functional size is a very popular and success approach when developing new software. However, functional size does not taken quality, complexity, security requirements and other non-functional but highly influential parameters into account. And what affects systems integration and todays social media projects in ICT even more: team size, personal skills, stakeholder’s interests, and other factors influencing people, process, product, or technology, must be taken into account for estimating.

In 2010, the GUFPI-ISMA working group on Software Benchmarking Standards identified 27 parameters affecting performance of ICT projects from various sources, including ISBSG, IFPUG and COCOMO. They have the potential to improve comparability of ICT projects for benchmarks across organizations and industries; however, so far they were not adopted on an international level.

This workshop shall establish a community of researchers and practitioners who are willing to share their experiences and insights for

1)       Using Performance Impact Factors (PIFs) for project estimation in ICT;

2)       Refining definition for PIFs;

3)       Understanding how to measure these factors can eventually be measured;

4)       Setting up a framework for benchmarking based on PIFs.

The workshop is planned for half-day or full day duration, depending upon the number of accepted workshop papers and the number attendees.

Call for Papers

The organizing committee is looking for short (15’), and full (30’) contributions to the following topics:

  • Estimation Models for ICT projects
  • Estimation Frameworks
  • Definition of PIFs
  • Measurement of PIFs
  • Influencing PIFs
  • Benchmarking approaches
  • Transition from estimates to actuals
  • Measuring actuals
  • Comparing estimate with actuals
  • Identifying cost controls
  • Transferring cost controls into actual effort

Organizing Committee

Günter Büren (DASMA), Ton Dekkers (NESMA), Thomas Fehlmann (SwiSMA), Mauricio Aguiar (IFPUG), Harold van Heeringen (ISBSG), Eberhard Kranich (DASMA), Luca Santillo (COSMIC / GUFPI-ISMA), Norbert Spies (SwiSMA)

Call for Participation

Participants will have an opportunity to discuss with experts the current state of the art in software and measurement methods in projects. The workshop will investigate whether an international standardization of PIFs is useful; if yes, feasible and, if yes, discuss ways how to achieve it.


Please submit your paper or short presentation proposal by September 6 to Notification for acceptance is being expected by September 20, 2013.
