DESMET was a DTI-backed project with the goal of developing and validating a methodology for evaluating software engineering methods and tools. The project identified nine methods of evaluation and a set of criteria to help evaluators select an appropriate method. Detailed guidelines were developed for three important evaluation methods: formal experiments, quantitative case studies and feature analysis evaluations. This article describes the way the DESMET project used the DESMET methodology to evaluate the DESMET methodology itself.
