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

In predictive projects, significant scope changes must go through integrated change control. The project manager's role is to analyze the impact (which she has done) and present it to the Change Control Board (CCB) or appropriate decision-makers. The CCB decides whether to approve, reject, or defer the change based on the presented analysis.

**Why not A:** Rejecting the change immediately because it affects the schedule is not the project manager's decision to make unilaterally. The project manager's role is to analyze and present the impact; the CCB or sponsor decides whether to approve or reject. Schedule impact alone does not automatically disqualify a change.

**Why not B:** Deferring the request to project close makes the change impossible to implement since the project will be finished. If the change has business value, it deserves proper evaluation now, not dismissal through deferral.

**Why not C:** Implementing the change without formal approval violates integrated change control. A 3-month schedule impact is significant and requires formal evaluation, approval from the appropriate authority, and baseline updates before work begins.
