Full set: 193 questions
Answer options
A: The inception phase continues until the architecture is proven
B: The transition phase ends when sufficient functionality is built
C: Agile and Lean life-cycles do not include inception and transition
D: The team may choose to evolve their life-cycle at some point Correct answer
Correct Answer:
D. The team may choose to evolve their life-cycle at some point
Explanation

Disciplined Agile explicitly allows teams to start with one life-cycle (e.g., Scrum-based Agile) and, as context or skill changes, evolve to another (e.g., Continuous Delivery). Adapting the life-cycle is a core DA practice that supports continuous improvement of the team’s Way of Working (WoW).

Why Incorrect

A. Inception ends when sufficient scope is understood, not solely when architecture is proven.
B. Transition ends when value is successfully released, not merely when “enough” functionality exists.
C. DA agile and lean life-cycles still include lightweight inception and transition phases.
