What is Agile and Disciplined? Disciplined Agile (DA) is a process decision system that puts people first and provides only lightweight feedback to help teams refine their processes according to each particular project’s unique needs. DA is in several respects close to the Crystal approach as a people-first agile framework. In fact, DA is intended to be a hybrid approach that incorporates XP, Scrum, Kanban, and other methodology elements.
