A Systematic Literature Review on the Influence of Enhanced Developer Experience on Developers' Productivity: Factors, Practices, and Recommendations

Context and Motivation – Developer eXperience (Dev-X) is a recent research area that focuses on developers perceptions, feelings, and values with respect to software development and software quality. Research suggests that factors and practices related to Dev-X can have a substantial impact on developer productivity (Dev-P). However, despite a large and diverse body of literature on factors that can impact Dev-P in general, there is no coherent and comprehensive characterization of how Dev-X-specific insights can influence developer productivity. Aims – In the presented research, we aim to provide a coherent, comprehensive characterization of factors and practices related to Dev-X, with a particular focus on those factors and practices that potentially affect Dev-P. Method – To this end, we performed a systematic literature review and identified 218 relevant papers in this area. We characterize the papers based on the related frameworks and concepts common to Dev-X and Dev-P as presented in the existing literature. Dev-X factors such as “work fragmentation” and practices such as “collaboration with owner-developer” are identified using a grounded-in-the-literature, content-analysis method, guided by the theory. For each Dev-X factor, we identify attributes that might be used to assess/ measure the current status (of an organization or project) regarding that factor and how that factor and its effects on productivity have been evidenced in the literature (mentioned vs. considered in questionnaires vs. substantiated with a more positivist evaluation). Results – We identify 33 Dev-X-related factors and 41 Dev-X-related practices, which are organized into 10 themes to summarize their influence. The results suggest that the availability of required resources, relevant expertise re the allocated tasks, and fewer interruptions are among the top positively impacting factors. Conversely, factors such as code complexity, heterogeneous contexts of tasks, and non-adherence to standardization harm Dev-X and Dev-P. Top industrial practices employed to mitigate the negative influence of factors include characterization-based task assignments, mental model support, and the timely evolution of technologies. Conclusions – Overall, this research suggests that organizations can influence Dev-P through improved Dev-X, incorporating suitable practices to mediate relevant factors in their context. Important in this regard are practices such as fragmenting large tasks, highlighting the utility of proposed tasks/changes to the developers, and promoting (developer) ownership of artefacts. Finally, our results point to areas where further research seems appropriate, i.e., where Dev-X factors/practices have been proposed as being impactful on Dev-P but not yet fully substantiated or explored as such (factors like “Nature of Activity” and practices like choosing practices/protocols appropriately).
