CAPM Practice: Explain when it is appropriate to use a predictive, plan-based approach

Methodology selection should align with project characteristics. Predictive suits projects with stability and defined requirements (even if complex). Adaptive suits projects with high uncertainty, novel technology, or evolving needs — where upfront planning would be speculative. Complexity alone doesn't dictate methodology; the nature of the uncertainty does.

**Why not A:** Project size alone does not determine the best methodology. Large projects with well-understood requirements can use predictive effectively, while large projects with high uncertainty may need adaptive approaches. Similarly, small projects can benefit from predictive methods when requirements are clear and stable.

**Why not B:** Complex projects do not always require adaptive approaches. Some complex projects have well-defined requirements and established processes (such as large construction or engineering projects) that are managed effectively using predictive methodology. Complexity alone is not the deciding factor.

**Why not C:** The organization's size is not the primary factor in methodology selection. Small organizations can use predictive approaches effectively, and large organizations often use adaptive methods. The project's characteristics — particularly requirement stability and uncertainty levels — drive the methodology choice.
