The answer is to implement a robust change control process and ensure all changes are reviewed by a change control board. This is correct because a formal change control system, as defined in the PMBOK Guide, provides a structured workflow for evaluating, approving, or rejecting requirement changes, directly mitigating the risk of uncontrolled scope creep that caused schedule delays and cost overruns in the previous project. On the CompTIA Project+ PK0-005 exam, this concept tests your understanding of integrated change control and the project manager’s role in preventing scope creep; a common trap is confusing a simple verbal agreement with a documented CCB approval. To mitigate requirement change risk with change control, remember that every change must pass through the CCB gate—think “CCB = Change Control Barrier” to block unapproved changes before they impact the triple constraint.
PK0-005 Project Management Concepts Practice Question
This PK0-005 practice question tests your understanding of project management concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A project manager is reviewing lessons learned from a previous similar project. That project suffered from frequent requirement changes that caused schedule delays and cost overruns. What should the project manager do to mitigate this risk on the current project?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement a robust change control process and ensure all changes are reviewed by the change control board.
Option D is correct because implementing a robust change control process with a change control board (CCB) ensures that all requirement changes are formally reviewed, approved, and documented before being incorporated. This directly addresses the risk of frequent, uncontrolled changes that caused schedule delays and cost overruns in the previous project, aligning with the PMBOK Guide's integrated change control process.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Proceed without changes since the lessons learned may not apply to this project.
Why it's wrong here
Ignoring lessons learned increases risk of repeating issues.
✗
Minimize stakeholder involvement to reduce the number of change requests.
Why it's wrong here
Reducing stakeholder involvement can lead to unmet expectations.
✗
Develop a rigid schedule that does not allow any changes to requirements.
Why it's wrong here
Rigidity may cause resistance or miss critical changes.
✓
Implement a robust change control process and ensure all changes are reviewed by the change control board.
Why this is correct
Change control manages changes systematically, reducing negative impacts.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that preventing all changes or reducing stakeholder involvement is effective risk mitigation, when the correct approach is to manage changes through a structured, approved process rather than avoid or suppress them.
Detailed technical explanation
How to think about this question
A robust change control process typically includes a formal change request form, impact analysis (cost, schedule, scope, quality), and approval by a CCB. The CCB should include key stakeholders and subject matter experts to evaluate trade-offs. In practice, even with a CCB, urgent changes may be handled via an emergency change process with post-implementation review, but all changes must be traceable to maintain baseline integrity.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the PK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
