Are Limited, Non-intrusive CMMI-based Appraisals Enough?
Stig Larsson and Fredrik Ekdahl
ABB Corporate Research, Västerås, Sweden
Abstract. An integral part of the strategy for performance improvement within the product development at ABB is the use of CMMI-based appraisals. Each appraisal represents an investment by the organization to lay the best possible foundation for improvements. The challenge is to balance the investment, the intrusiveness and the benefits. Depending on different organizational characteristics, different kinds of appraisals should be used. All appraisals are driven by data collection and consequently the quality of an appraisal depends on the data collection methods used. In this paper we outline strategies used in ABB for selection of appropriate CMMI appraisals and data collection methods. Early results indicate that the use of a series of appraisals can be a way to overcome the resistance in an organization. We also claim that a discussion is needed on the reliability and validity of the appraisal methodologies and on the feasibility to base decisions regarding process improvement strategies on appraisal results.
