The correct first step is to analyze the critical path and determine if resource addition will help. This is because blindly adding resources to a project that is behind schedule can actually worsen delays due to Brooks’ Law, which states that adding manpower to a late software project makes it later. The critical path contains the sequence of tasks that directly determine the project’s duration, and only tasks on this path can potentially shorten the timeline when resources are added; non-critical tasks already have float, and adding resources to them does nothing for the overall schedule. On the CompTIA Project+ PK0-005 exam, this scenario tests your understanding of schedule compression techniques and the risks of crashing without analysis—a common trap is assuming more resources always mean faster delivery. A helpful memory tip is “Check the path before you crash,” reminding you to always analyze the critical path before applying crashing or adding resources.
PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
This PK0-005 practice question tests your understanding of basics of it infrastructure and it project management.

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 to migrate on-premises email to Office 365 is behind schedule. The project sponsor asks the project manager to add more resources to accelerate the timeline. The project manager should first:

Correct answer & explanation
✓
Analyze the critical path and determine if resource addition will help
Adding resources to a project that is behind schedule can sometimes worsen the delay due to Brooks' Law, especially if the critical path involves tasks that are not parallelizable. The project manager must first analyze the critical path to determine if adding resources will actually reduce the duration of critical tasks, such as mailbox migration batches or DNS cutover steps, or if it will introduce coordination overhead that negates any gains.
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.
✗
Add two additional migration specialists immediately
Why it's wrong here
Adding resources without analysis may not improve speed and can increase coordination overhead.
✗
Update the project schedule to reflect the new timeline
Why it's wrong here
Updating the schedule without addressing the root cause is premature.
✓
Analyze the critical path and determine if resource addition will help
Why this is correct
Analyzing the critical path shows where compression is possible and if extra resources are beneficial.
Clue confirmation
The clue word "first" in the question point toward this answer.

✗
Reduce the project scope by deferring non-critical features
Why it's wrong here
Scope reduction should be approved through change control, not as a first response.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume adding resources always speeds up a project (the 'resource myth'), but Cisco tests the understanding that the critical path must be analyzed first to avoid violating Brooks' Law or hitting infrastructure constraints.
Detailed technical explanation
How to think about this question
In email migration projects, the critical path often includes sequential dependencies such as directory synchronization, mailbox data extraction, and cutover validation. Adding parallel resources to a sequential task (e.g., splitting a single migration batch into multiple parallel batches) can reduce duration only if the underlying infrastructure (e.g., network bandwidth, Exchange throttling limits) supports concurrent migrations without contention. Real-world scenarios often involve Office 365 migration limits (e.g., 150 concurrent migrations per batch) that cap the benefit of adding more specialists.

→Watch for words such as best, first, most likely and least administrative effort.

Key takeaway

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
