Evolution of Software Processes and of their Models: A Multiple Strategy Approach

This paper deals with a new approach to modify software process models and their software processes. Such an approach, in contrast with existing ones, supports the different evolution strategies for the software process models, and allows the adaptation of software process during execution. The integration of these two types of evolution is based on a chaining of phases (generation/evolution/simulation/ execution). It allows the change of software process models as and when executed without inconsistencies, to perfect software processes through simulation and to define new ones dynamically.
