An Approach for Evolution-Driven Method Engineering
This chapter considers the evolutionary perspective of method engineering. It presents an approach for method engineering supporting evolution of an existing method, model, or meta-model into a new one satisfying a different engineering objective. The authors hope that this approach could be helpful for a project-specific method construction. This approach proposes several different strategies to evolve from the initial paradigm model to a new one and provides guidelines supporting these strategies. The approach has been evaluated in the Franco-Japanese research project around the Lyee methodology. A new model called Lyee User Requirements Model has been obtained as an abstraction of the Lyee Software Requirements Model. The chapter illustrates this evolution case.
