What are the three stages of the Build phase?

• A. Planning, Development, Testing
• B. Planning, Disciplined Development, Inspect and Adapt
• C. Development, Testing, Adapting
• D. Disciplined Development, Inspecting, Adapting

Answer: (B)

In the Build phase, the work breaks into planning what to build, executing with disciplined development practices, and then reviewing and adjusting based on feedback. The three stages are: Planning, Disciplined Development, Inspect and Adapt.

Planning sets the direction, priorities, and how success will be measured, so the team has a clear roadmap for what to build and how it will be validated. Disciplined Development emphasizes a structured, quality-focused approach to actually building the solution—following standards, performing necessary tests, and integrating components properly. Inspect and Adapt provides a formal feedback loop: after a cycle of work, you review results, gather learnings, and modify plans or processes to improve in the next cycle.

Other options miss one of these elements or use alternative terms that don’t align with the structured Build phase flow, such as omitting planning, replacing the feedback loop with a general “testing” or using different labels for the improvement step.
