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

The business case documents the business need, expected benefits, and justification for the project. The project charter establishes the project's objectives and boundaries. Reviewing these documents against current conditions confirms whether the project's original rationale still holds and whether the expected benefits are still achievable — essential for ensuring continued organizational value.

**Why not A:** The stakeholder register identifies stakeholders, their interests, and influence levels. While useful for engagement planning, it does not contain the business justification or expected benefits needed to confirm ongoing alignment with the original rationale for the project.

**Why not B:** The lessons learned register captures insights gained during the project. It is backward-looking and focuses on what has been learned, not on whether the project's original business justification remains valid.

**Why not C:** The project schedule shows planned and actual dates for activities. While it indicates whether the project is on time, it does not address whether the business need that justified the project still exists or whether expected benefits are still achievable.
