In order of importance, the architectural views of the DA tool kit are:
1. Mindset. Mindset addresses the issue of “How do you think?” The DA mindset is captured in the form of principles, promises, and guidelines and it provides a common foundation for DA practitioners. Disciplined agilists believe in the principles, so we promise to adopt these behaviors and follow these guidelines when doing so. Furthermore, each process blade extends the DA mindset with one or more philosophies that are specific to that process blade. Figure 2 depicts the mindset for data management where you can see that several philosophies specific to that blade build upon the base DA mindset. We do this because practitioners of each blade, such as Finance, Sales, Enterprise Architecture, Governance, and so one each have their own specific belief systems, priorities, and experiences. By extending the foundational principles, promises, and guidelines with philosophies, the DA tool kit embraces and respects the different viewpoints that people bring to the mix.
