Toward a Simplified Software Process Improvement Framework for Small Software Development Organizations

Abstract

ABSTRACTFor decades, software developers have struggled with delivering high-quality systems. To address the issues related to poor quality software, many use software process improvement (SPI) models such as the capability maturity model integration (CMMI) to guide the software development process. However, implementing these initiatives in small software development organizations is particularly challenging due to the high cost and complexity involved. To address these issues, this study proposes a simplified SPI framework (based on the CMMI) that small organizations can use to help improve software development. Conducted in four English-speaking Caribbean countries, this study uses focus groups with information systems (IS) professionals to arrive at a consensus on the content of a simplified SPI model. The model was assessed using data from a survey of small software development organizations’ practices across the four countries. The resulting model, called the SPI model for small organizations (SPIM-S) is deemed less cumbersome and complex to implement, in comparison to its counterpart, the CMMI. It should therefore be less disruptive to implement—offering practitioners an alternative guide in their quest for high-quality software.
