Principle-Based versus Rule-Based

Similar to empirical versus prescriptive methods, a related way to describe agile methods is as more principle-based than rule-based. Rather than a predefined set of rules regarding the many roles, team organization, responsibilities, relationships, and activities, the team and manager are primarily guided by the principles embodied in the Agile Manifesto and Principles. Agile project management is more than a set of practices it is a mindset.
