PMP Question #1150: Real Exam Question with Answer & Explanation

Question

A project team is in the planning stage and has prepared a list of activities and completed sequencing the activities. During a review, the team noted that there is a dependency missing between: - Test the product - Release to customer According to the quality management plan, the product must be tested before being released. How should the project manager enter this dependency?

Options

• AStart to start
• BFinish to start
• CFinish to finish
• DStart to finish

Explanation

During planning, the project team identified a missing dependency: the product must be tested before it can be released to the customer. This sequential relationship needs to be accurately represented in the schedule.

Common mistakes.

• A. Start-to-Start (SS) means the successor activity can start when the predecessor activity starts, which does not ensure that testing is finished before the release begins.
• C. Finish-to-Finish (FF) means the successor activity can finish when the predecessor activity finishes, which would allow the release to start long before testing is complete.
• D. Start-to-Finish (SF) means the successor activity cannot finish until the predecessor activity starts, a rarely used dependency type that does not fit the requirement of testing completing before release.
