Quality over Compliance
Adherence to a process does not necessarily guarantee a quality product. This facet underscores the importance of delivering working, valuable software, even if it means deviating from established procedures. A project might strictly follow all steps of a formal review process, but if the resulting software is flawed, the process has failed in its ultimate goal. The value is in the working software, not in the process followed.
-
Empowerment and Autonomy
This value fosters a culture of self-organization and decision-making within development teams. Instead of relying on rigid hierarchical structures and predefined roles, individuals are empowered to take ownership of their work and make choices that best serve the project’s goals.
