Toward Evidence-Based Software Engineering for Cross-Functional Team Optimization
Cross-functional teams are a central organizational model in contemporary software engineering fueled by practices such as Agile development, DevOps and Continuous Integration/Continuous Deployment (CI/CD). Although widely adopted, there is limited empirical support for the effectiveness of these practices in cross-functional teams. This paper presents evidence based software engineering for improving the performance of cross-functional teams. We propose a structured optimization framework which connects modern software engineering principles to measurable performance incentives. The framework is empirically validated on data from real cross-functional software teams, including delivery, quality and collaboration metrics. We show empirical evidence that we have increased deployment frequency, reduced time to release cycle, decreased defect density, improved recovery efficiency, and enhanced collaboration across teams through data-driven optimization. The results reveal that systematic and sustainable performance improvements are achieved through data driven decision making. The contributions of this paper move along the evidence-based software engineering and propose a theoretical and empirically grounded support for optimizing cross-functional software teams.
