Abstract. DevOps is an approach in which traditional software engineering roles are merged and communication is enhanced to improve the production release frequency and maintain software quality. There seem to be benefits in adopting DevOps but practical industry experiences have seldom been reported. We conducted a qualitative multiple-case study and interviewed the representatives of three software development organizations in Finland. The responses indicate that with DevOps, practitioners can increase the frequency of releases and improve test automation practices. DevOps was seen to encourage collaboration between departments which boosts communication and employee welfare. Continuous releases enable a more experimental approach and rapid feedback collection. The challenges include communication structures that hinder cross-department collaboration and having to address the cultural shift. Dissimilar development and production environments were mentioned as some of the technical barriers. DevOps might not also be suitable for all industries. Ambiguity in the definition of DevOps makes adoption difficult since organizations might not know which practices they should implement for DevOps.
Abstract. [Context and motivation]In order to build successful software products and services, customer involvement and an understanding of customers' requirements and behaviours during the development process are essential.[Question/Problem] Although continuous deployment is gaining attention in the software industry as an approach for continuously learning from customers, there is no common overview of the topic yet. [Principal ideas/results] To provide a common overview, we conduct a secondary study that explores the state of reported evidence on customer input during continuous deployment in software engineering, including the potential benefits, challenges, methods and tools of the field.[Contribution] We report on a systematic literature review covering 25 primary studies. Our analysis of these studies reveals that although customer involvement in continuous deployment is highly relevant in the software industry today, it has been relatively unexplored in academic research. The field is seen as beneficial, but there are a number of challenges related to it, such as misperceptions among customers. In addition to providing a comprehensive overview of the research field, we clarify the gaps in knowledge that need to be studied further.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
