Context: Collaboration is an important aspect of DevOps. However, researchers continue to report problems with collaboration between development and operations. Objective: We aim to contribute to a better understanding of collaboration in the context of DevOps, especially to aid in adopting DevOps. Method: We conducted a literature review on collaboration and corresponding success factors. For practice we classified the factors into factors influencing the likelihood of collaboration and factors influencing the performance of collaboration, to aid in the adoption of DevOps. We will validate the factors of collaboration in a DevOps context using an inductive approach, i.e. semi-structured interviews and document studies. Results: We developed an initial framework of success factors and classified the found success factors. Subsequently we conducted two interviews. We learned that most factors are considered as important, however few factors could be confirmed and no more factors are added. We will interview the other respondents to prove the applicability of the framework. Which may identify promising avenues for further development of the framework. Conclusions: This is study is not finalized yet, therefore we cannot fully answer the main research question.
