Abstract

In this paper we present components of a newly developed software process improvement model that aims to represent key practices in requirements engineering (RE). Our model is developed in response to practitioner needs highlighted in our empirical work with UK software development companies. We have now reached the stage in model development where we need some independent feedback as to how well our model meets our objectives. We perform this validation through involving a group of software process improvement and RE experts in examining our RE model components and completing a detailed questionnaire. A major part of this paper is devoted to explaining our validation methodology. There is very little in the literature that directly relates to how process models have been validated, therefore providing this transparency will benefit both the research community and practitioners. The validation methodology and the model itself contribute towards a better understanding of modelling RE processes.
