A project sponsor wants to know when the plan changed to ship the deliverables to a new location. To determine the answer, the project manager should FIRST review the:

The project management plan reflects the current approved state of the project but may not contain the historical narrative or timestamp of when a specific change was decided.

Scope statements and the issue log track scope boundaries and outstanding issues respectively but do not typically record the specific moment a logistical decision such as a delivery location change was made.

The project dashboard and status reports summarize current performance metrics and may reference changes but do not capture the original decision context the way meeting minutes do.

Action items and meeting minutes serve as the chronological record of decisions made during project meetings, including changes to plans such as a new delivery location. Reviewing them allows the project manager to pinpoint the exact meeting where the decision was made, who was present, and the rationale discussed. This is the most direct and time-efficient first step before consulting broader documents.
