Towards a systematic metric based approach to evaluate SCAMPI appraisals

Abstract

CMMI SCAMPI based appraisals are used worldwide to assess the process quality of organizations. In this paper we introduce a metric-based approach to assess and improve CMMI SCAMPI appraisals. To have a sound basis we at first present an appraisal meta model which defines all types of appraisal elements and their relationships. This meta model can be instantiated to get a concrete SCAMPI appraisal process, offering a precise roadmap for conducting appraisals. Based on the meta model two appraisal quality metrics are defined to systematically assess appraisal activities as well as phases and to support the improvement of appraisals. We describe the definition of these metrics in detail and give some metric interpretation guidelines. © 2009 Springer Berlin Heidelberg.
