The answer is the risk of rework due to incomplete deliverables from previous phases. Fast-tracking compresses the schedule by overlapping phases that would normally run sequentially, which means a later phase begins before the earlier phase’s outputs are fully verified. This creates a high probability of rework if those incomplete deliverables contain errors or require changes, potentially erasing any time gains and destabilizing the schedule. On the CompTIA Project+ PK0-005 exam, this concept tests your understanding that fast-tracking trades schedule compression for increased risk, not cost reduction—a common trap is confusing it with crashing, which adds resources. A useful memory tip: think of fast-tracking as “racing before the finish line,” where you risk having to re-run the race if the first lap was wrong.
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 assigned to a new project that has a tight deadline. The sponsor wants to fast-track the project by overlapping some phases. Which project management concept should the PM be most concerned about regarding this approach?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Risk of rework due to incomplete deliverables from previous phases.
Fast-tracking involves overlapping project phases that would normally be sequential. The primary risk is that work on a later phase begins before the deliverables from the previous phase are fully complete and verified. This increases the probability of rework if the earlier deliverables contain errors or require changes, which can negate any time savings and introduce schedule instability.
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.
✗
Longer overall project duration.
Why it's wrong here
Fast-tracking is intended to shorten, not lengthen, duration.
✓
Risk of rework due to incomplete deliverables from previous phases.
Why this is correct
Fast-tracking increases the likelihood of rework because activities are overlapped before prior deliverables are complete.

Read the scenario before looking for a memorised answer.
✗
Increased cost of additional resources.
Why it's wrong here
While cost may increase, it is not the primary concern; fast-tracking primarily affects risk.
✗
Reduced quality of final product.
Why it's wrong here
Quality might suffer if rework occurs, but the immediate risk is rework.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between fast-tracking (overlapping phases) and crashing (adding resources), and the trap here is that candidates mistakenly focus on cost or duration rather than the core risk of rework from incomplete predecessor deliverables.
Detailed technical explanation
How to think about this question
In project management, fast-tracking is a schedule compression technique that applies leads to logical relationships (e.g., start-to-start with a lag). The critical path method (CPM) shows that overlapping phases increases the number of activities with finish-to-start dependencies that are now partially parallel, amplifying the impact of any variance in predecessor completion. In practice, this often manifests as increased change requests and defect rates during integration testing, as seen in software projects where coding begins before requirements are fully baselined.

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.
