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

Predictive approaches use integrated change control, which is deliberate but rigid — changes require formal requests, impact analysis, approval, and baseline updates. When requirements are unclear, the natural process of discovery generates frequent changes that are expensive and disruptive in a predictive framework. Adaptive approaches handle this through planned iteration rather than exception-based change control.

**Why not A:** Predictive approaches are well-suited for large, complex projects when requirements are stable and well-understood. Complexity alone does not disqualify predictive methodology. Many of the largest construction, infrastructure, and defense projects use predictive approaches effectively.

**Why not B:** Predictive approaches include comprehensive risk management tools — risk registers, qualitative and quantitative risk analysis, risk response planning, and risk monitoring. The risk management processes in PMBOK are specifically designed for predictive project management.

**Why not C:** Predictive approaches do allow for stakeholder feedback, typically through formal status reporting, milestone reviews, and stage-gate approvals. While the feedback mechanisms are more structured and less frequent than adaptive approaches, they exist. The core issue with unclear requirements is that formal change control makes incorporating feedback costly, not that feedback is impossible.
