Implementing software process improvement initiatives: An empirical study

In this paper we present findings from our empirical study of software process improvement (SPI) implementation. We aim to provide SPI practitioners with insight into designing appropriate SPI implementation initiatives in order to achieve better results. Thirty-four interviews were conducted with Australian practitioners. Three SPI implementation issues were investigated: reasons for embarking on SPI initiatives, SPI benefits to the management, and factors that play a positive role in SPI implementation. We have found that most common reasons for embarking on SPI initiatives are to: improve the quality of software developed, reduce software development cost, and increase productivity. Our results show that 7 1 % of the practitioners said that SPI initiatives provided clear benefits to the management. We have also found that most frequently cited SPI implementation factors are: SPI awareness, defined SPI implementation methodology, experienced staff, staff time and resources, senior management commitment and training. Our aim of conducting this study is to provide a SPI implementation framework for the design of effective SPI implementation initiatives.
