Handling Vendor Error and Schedule Delay: Crashing and Fast-Tracking
You are managing a network upgrade project for a large corporation. The project involves replacing outdated switches and routers across three data centers. During the execution phase, you discover that one of the key vendors has shipped the wrong model of switches for Data Center B. The correct switches have a lead time of four weeks, which will delay the project by three weeks. The project sponsor is pressuring you to meet the original deadline. The project budget has some contingency reserves. What should you do?
Quick Answer
The correct answer is to evaluate the schedule to see if crashing or fast-tracking can recover the delay, then order the correct switches. This is the right move because project management best practice dictates that when a vendor error causes a schedule delay, you first attempt schedule compression techniques—crashing, which adds resources to critical path tasks, or fast-tracking, which runs normally sequential tasks in parallel—before accepting a slip. On the CompTIA Project+ PK0-005 exam, this scenario tests your ability to apply the "evaluate before escalate" principle, especially when contingency reserves are available to fund compression. A common trap is to immediately order the switches and accept the delay, but the exam wants you to proactively recover the schedule first. Memory tip: think "Crash or Track before you fall back"—always try to compress the schedule before accepting a delay.
⚠ Common exam trap
It's easy for candidates to choose Option A (accepting the delay) because they think it's the 'safe' choice, but the exam expects you to demonstrate proactive schedule management by first attempting recovery techniques before escalating or accepting delays.

Correct answer & explanation
✓
Evaluate the schedule to see if crashing or fast-tracking can recover the delay, then order the correct switches.
It aligns with the project management principle of first attempting to recover the schedule using techniques like crashing (adding resources) or fast-tracking (performing tasks in parallel) before accepting a delay. Since the project has contingency reserves, you can potentially expedite the correct switch delivery or re-sequence tasks to absorb the three-week delay, preserving the original deadline. Ordering the correct switches immediately is necessary, but you must first evaluate if schedule compression can offset the impact, making D the most proactive and effective response.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Order the correct switches immediately and accept the three-week delay.
Why it's wrong here
Accepting the delay without first drawing on the contingency reserves ignores the budget explicitly set aside to absorb this kind of vendor risk. It is tempting because ordering the correct switches is technically sound, yet the reserves exist to fund expediting, overtime or alternate sourcing to protect the deadline.
- ✗
Escalate to the sponsor and ask for a deadline extension.
Why it's wrong here
Escalation transfers the decision without first applying the contingency reserves the stem explicitly provides; the delay is three weeks, not an unmanageable overrun. It is tempting because sponsors authorise baseline changes, but that step follows, not replaces, using available reserves to recover the schedule.
- ✗
Use the wrong switches in Data Center B and plan to replace them later.
Why it's wrong here
Installing incompatible switches risks network outages and voids vendor support, and the later replacement would incur additional downtime and cost. It is tempting as a schedule-compression tactic when the hardware is functionally similar, but the stem gives contingency reserves precisely to absorb the correct procurement route.
- ✓
Evaluate the schedule to see if crashing or fast-tracking can recover the delay, then order the correct switches.
Why this is correct
Evaluating crashing or fast-tracking directly addresses the three-week delay constraint while the correct switches are ordered, using contingency reserves if needed. Crashing adds resources to critical-path activities; fast-tracking overlaps sequential tasks. This recovers schedule without compromising the specified switch models, satisfying the sponsor's deadline pressure through approved schedule compression techniques.

Same concept, more angles
2 more ways this is tested on PK0-005
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A project manager is leading a construction project. The project sponsor has requested that the project be completed one month earlier than originally planned. Which THREE actions should the project manager take to assess the feasibility of this request? (Choose three.)
hard- ✓ A.Evaluate schedule compression techniques such as crashing or fast-tracking.
- ✓ B.Analyze the critical path to identify activities that can be compressed.
- C.Increase the project scope to justify the shorter timeline.
- ✓ D.Assess resource availability and the possibility of adding more resources.
- E.Reduce the quality standards to speed up work.
Why A: Schedule compression techniques like crashing (adding resources) or fast-tracking (performing tasks in parallel) are standard methods to shorten a project's duration without changing scope. The project manager should evaluate these to determine if the one-month acceleration is technically feasible given the project's constraints.
Variation 2. A project manager is reviewing the project's critical path. Two tasks on the critical path have float of zero, and a third task has a float of three days. The sponsor asks to compress the schedule by two days. Which action should the PM take?
hard- A.Apply fast-tracking to the task with three days of float.
- ✓ B.Apply crashing only to tasks on the critical path with zero float.
- C.Reduce the scope of tasks with the largest float.
- D.Add resources to all tasks on the critical path.
Why B: Schedule compression must focus on the critical path to reduce project duration. Tasks with zero float are on the critical path, so crashing them (adding resources or overtime) can directly shorten the schedule. The task with three days of float is not on the critical path, so compressing it would not reduce overall project duration.
