The impacts of quality and productivity perceptions on the use of software process improvement innovations

Numerous software process improvement (SPI) innovations have been proposed to improve software development productivity and system quality; however, their diffusion in practice has been disappointing. This research investigates the adoption of the Personal Software Process on industrial software projects. Quantitative and qualitative analyses reveal that perceived increases in software quality and development productivity, project management benefits, and innovation fit to development tasks, enhance the usefulness of the innovation to developers. Results underscore the need to enrich current technology acceptance models with these constructs, and serve to encourage project managers to adopt formal SPI methods if developers perceive the methods will have positive impacts on their productivity and system quality.
