Disciplined Agile (DA) milestones are based on the concept ofLean governance, which is focused on ensuring that agile practices are aligned with the organization's overall objectives while minimizing bureaucracy. In the DA framework, milestones provide lightweight checkpoints throughout the lifecycle to ensure that the team is on track to meet its objectives and deliver value. These milestones are not about documentation or merely following a predefined lifecycle but are instead focused on achieving business value in a lean and efficient manner.
* A. Continuous integrationis a practice rather than a basis for milestones.
* B. Documentationis not a central focus of DA milestones.
* D. Lifecyclerefers to the various phases in the DA process, but milestones are specific checkpoints within these phases guided by lean governance principles.
Thus,C. Lean governanceis the correct answer, as it embodies the principles upon which Disciplined Agile milestones are established.
