The Disciplined Agile (DA) mindset is captured in the form of principles, promises, and guidelines. Disciplined agilists believe in the DA principles, so we promise to adopt these behaviours and follow these guidelines when doing so. There is a purpose for each aspect of the mindset:
Principles. The principles provide a philosophical foundation for business agility. They are based on both lean and flow concepts.
Promises. The promises are agreements that we make with our fellow teammates, our stakeholders, and other people within our organization whom we interact with. The promises define a collection of disciplined behaviours that enable us to collaborate effectively and professionally.
Guidelines. These guidelines help us to be more effective in our way of working (WoW) and in improving our WoW over time.
