PK0-005 Project Management Concepts Practice Question
A project manager is preparing to close out a construction project. The final deliverable was accepted by the customer two weeks ago, but several team members have already been reassigned to a new initiative. The project manager still needs to obtain formal sign-off from the customer, archive project documents, and release remaining resources. Which activity should the project manager complete FIRST in the closing phase?
⚠ Common exam trap
The trap here is assuming that administrative closing tasks like archiving can begin as soon as the deliverable is handed over, when in fact formal acceptance must be documented first.

Correct answer & explanation
✓
Obtain formal acceptance and sign-off of the final deliverable from the customer
Formal acceptance and sign-off of the final deliverable is the gateway activity in the closing phase. Without documented customer acceptance, the project cannot be declared complete, and activities such as archiving, releasing resources, and capturing lessons learned would rest on an unverified outcome. Securing sign-off first ensures all remaining closing activities reflect a confirmed, accepted deliverable and protects the project manager from contractual or payment disputes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Archive all project documents and lessons learned in the organizational repository
Why it's wrong here
Archiving documents and lessons learned is a valid closing activity, but it should not be the first step. Formal acceptance must be obtained and confirmed before the project manager can consider the project complete and proceed to archive records. Performing archival work before securing final sign-off risks recording incomplete or unverified project outcomes, and the customer could still raise objections that would invalidate the archived materials.
- ✗
Conduct a lessons learned session with the remaining stakeholders
Why it's wrong here
Lessons learned capture is valuable, but it is more meaningful once the project outcome is confirmed. Holding the session before formal acceptance means the team may discuss an outcome that is not yet validated, and any late customer feedback could change the conclusions. The project manager should first obtain sign-off, then capture lessons learned with accurate, complete information about the final accepted result.
- ✓
Obtain formal acceptance and sign-off of the final deliverable from the customer
Why this is correct
Formal acceptance of the final deliverable is the trigger that allows the project to move into closing. Until the customer provides documented sign-off, the project cannot be considered complete, and contractual or payment obligations may remain open. The project manager should secure this acceptance first so that subsequent activities such as archiving, releasing resources, and capturing lessons learned reflect a verified, accepted outcome rather than an unconfirmed one.
- ✗
Release all remaining project team members and close their assignments
Why it's wrong here
Releasing team members is part of closing, but doing it before formal acceptance is risky. If the customer rejects the deliverable or requests rework, the project manager would need those resources back, and reassigning them prematurely could cause delays and additional cost. Resource release should follow confirmed acceptance so the team remains available to address any final acceptance-related issues or corrections.
