A maturity model for the implementation of software process improvement: an empirical study

We have adopted a CMMI approach and developed a maturity model for SPI implementation in order to guide organizations in assessing and improving their SPI implementation processes. The basis of this model is what we have studied in the SPI literature and an empirical study we have carried out. In the design of this maturity model we have extended the concept of critical success factors (CSFs). We have conducted CSF interviews with 23 Australian practitioners. We have also analysed CSFs and critical barriers using 50 research articles (published experience reports and case studies). This maturity model has three dimensions--maturity stage dimension, CSF dimension and assessment dimension. It provides a very practical structure with which to assess and improve SPI implementation processes.
