Modeling Software Process Maturity on Development Team Size

Abstract

Software projects are not usually completed and delivered on time and on budget. This failure has been traced to immature development models being used by developers. Five selected reputable software development organizations’ models were studied in Lagos State, Nigeria using Capability Maturity Model (CMM) interview questions provided by the Carnegie Mellon University Software Engineering Institute. For each of the Organizations, one past and one current projects’ processes were studied. Observation and Interview techniques were used to gather information about the software development process used by each of the organizations. Collected data were analyzed and interpreted with simple percentages and graphs. Results show that only one organization attained (CMM) level two with 84.09% while the rest of the organizations did not. A linear regressive model of maturity levels (ML) of the organizations at level two on the development team size (DTS) shows that ML increases as DTS decreases.
