Reidar Conradi, NTNU:
   Software Process Evolution, a framework and some experiences

The talk presents how to adopt a categorization framework for managing
evolution in software projects to identify project profiles and evolution
patterns, and to suggest improvements to better support frequent
evolutions. Based on analysis of collected evolution data from a case
study, we elaborate a QIP-inspired method and own techniques to evolve
corresponding process models in our Process-centered Software Engineering
Environment, called EPOS. The method also describes how to synthesize and
reuse evolution experience from completed projects to improve planning and
esitmation in new similar projects. The collected data demonstrates that
requirement changes which are detected in later development phases, are
major causes for cost overruns in the studied organization.
