An Approach for Evolution-Driven Method Engineering

This work considers the evolutionary perspective of method engineering. It presents an approach for method engineering based on the evolution of an existing method, model or meta-model into a new one satisfying a different engineering objective. This approach proposes several different strategies to evolve from the initial paradigm 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 paper illustrates this evolution case.
