De fyra Hörnstenarna : En fallstudie om kontinuerliga leveranser av mjukvara i agil systemutveckling

When the traditional approach to system development transitioned over to agile methods the demand for ways to continuously deliver valuable software increased. With the increasing interest in these methods the umbrella term DevOps were introduced in 2008. DevOps is the practice to shorten the time, as well as streamlining the process, between changes in the source code and when it reaches the customer. This study aimed at investigating the process of adopting DevOps practices and identify success factors and challenges in this transition. We conducted a quality approached case study on a DevOps team in a multinational IT-consulting firm. Four explorative interviews were conducted based on categories identified in relevant literature as well as basis provided by the case company. We discovered that an implementation of continuous practices is far more complex than we initially thought. It is related to more fields outside the technical aspect that must be considered during a transition. Our findings include four critical success factors for a successful DevOps implementation; conscious staff, conscious organization, functional infrastructure and adapted business model. Embedded in these critical success factors we were able to identify challenging fields that should be considered when adopting DevOps. These critical success factors and challenges was the basis for our model presented in the study
