Although software development teams increasingly use Platform-as-a-Service (PaaS), a minimal amount is known regarding the impact of PaaS on software development. We explored the impact of PaaS on software development through a grounded-theory study, conducting 48 interviews in 16 teams. The data turned our attention to the affordances, or potentials for action, that PaaS provides to software development teams. Two key affordances emerging from our data analysis were self-organizing and triggering continuous feedback. Actualizing these affordances helped accelerate the collective learning processes that underlie software development, thus supporting software development teams in their quest for agility. Our emerging theory explains how, why, and when these affordances arise. The key contribution of our paper lies in unveiling how the use of cloud computing technology can transform technology-mediated collective learning activities by helping to remove barriers to rapid feedback. Our findings also imply that organizations can leverage PaaS to facilitate the transition to agile and continuous software development practices, in particular in conjunction with cross-functional team designs.

Read publicationSoftware development teams increasingly adopt platform-as-a-service (PaaS), i.e., cloud services that make software development infrastructure available over the internet. Yet, empirical evidence of whether and how software development work changes with the use of PaaS is difficult to find. We performed a grounded-theory study to explore the affordances of PaaS for software development teams. We find that PaaS enables software development teams to enforce uniformity, to exploit knowledge embedded in technology, to enhance agility, and to enrich jobs. These affordances do not arise in a vacuum. Their emergence is closely interwoven with changes in methodologies, roles, and norms that give rise to self-organizing, loosely coupled teams. Our study provides rich descriptions of PaaS-based software development and an emerging theory of affordances of PaaS for software development teams.
