Challenges of shared decision-making: A multiple case study of agile software development

Context: Agile software development changes the nature of collaboration, coordination, and communication in software projects. Objective: Our objective was to understand the challenges of shared decision-making in agile software development teams. Method: We designed a multiple case study consisting of four projects in two software product companies that recently adopted Scrum. We collected data in semi-structured interviews, through participant observations, and from process artifacts. Results: We identified three main challenges to shared decision-making in agile software development: alignment of strategic product plans with iteration plans, allocation of development resources, and performing development and maintenance tasks in teams. Conclusion: Agile software development requires alignment of decisions on the strategic, tactical, and operational levels in order to overcome these challenges. Agile development also requires a transition from specialized skills to redundancy of functions and from rational to naturalistic decision-making. This takes time; the case companies needed from one to two years to change from traditional, hierarchical decision-making to shared decision-making in software development projects.
