Non-adoption of CMMI software process improvement methodology by Sri Lankan software companies

Abstract

In the domain ofsoftware process improvement, CMMI has been recognized as one of the leading standards of process improvement methodologies. However, over the years the literature reveals that only a few Sri Lankan software companies have managed to successfully implement CMMI and obtain Level 3 certification. This research investigates the reasons as to why CMMI has failed to manifest within the Sri Lankan software industry as a popular choice for process improvement. In view of realising this objective, this research provides an outlook on strategies used by CMMI non-certified companies to improve their processes. Further, this study propose a model framework, which can be used by the IT policy makers in deciding whether CMMI implementation can be justified or whether existing company specific software process improvement strategies are comprehensive enough to address the requirements ofthe stakeholders. In this study a theoretical framework is used which consists of a set of variables identified as factors affecting non-adoption of CMMI from the literature in a similar domain. Applicability of this framework within the prevalent conditions in the Sri Lankan software industry is evaluated based on an empirical study carried out using data collected from Sri Lankan IT export companies which do not have the CMMI level-3 certification. This research revealed significant correlations between nonadoption of CMMI and variables such as demand for CMMI, benefits of CMMI, applicability of CMMI, financial consideration in CMMI implementation, involvement ofCMMI consultant and organization process improvement priority.
