Which Tool Tracks Tasks, Dependencies, and Critical Path?
A project manager is using a tool to track project tasks, dependencies, and resource assignments. The team needs to see the critical path and adjust schedules when tasks are delayed. Which tool should the project manager use?
Quick Answer
The answer is a Gantt chart. This tool is correct because it visually maps project tasks along a timeline, showing dependencies, durations, and resource assignments, while explicitly highlighting the critical path—the longest sequence of dependent tasks that determines the project’s minimum duration. When a task is delayed, the Gantt chart allows the project manager to dynamically adjust the schedule and immediately see the impact on the critical path, making it essential for schedule management and impact analysis. On the CompTIA Project+ PK0-005 exam, this question tests your ability to distinguish between scheduling tools; a common trap is confusing the Gantt chart with a network diagram, which shows task logic but lacks the timeline and resource view. Remember the memory tip: “Gantt gives the glance”—it’s the only tool that combines a timeline, dependencies, and the critical path in one visual, so you can track delays at a glance.
⚠ Common exam trap
Candidates often confuse a Kanban board's visual workflow management with the scheduling and dependency-tracking capabilities of a Gantt chart, leading them to pick Kanban when the question explicitly requires critical path and schedule adjustment features.

Correct answer & explanation
✓
Gantt chart
The Gantt chart is the correct tool because it visually displays project tasks, their dependencies, durations, and resource assignments along a timeline. It explicitly shows the critical path (the longest sequence of dependent tasks) and allows the project manager to adjust schedules dynamically when tasks are delayed, making it ideal for schedule management and impact analysis.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Pareto chart
Why it's wrong here
A Pareto chart ranks causes by frequency to identify the vital few, so it cannot model task dependencies or compute a critical path. It is tempting because it is a genuine project quality tool, and it would be the right choice when prioritising defect categories or root causes during a continuous-improvement review.
- ✗
RACI matrix
Why it's wrong here
A RACI matrix assigns responsibility, accountability, consultation and information roles; it holds no duration, dependency or float data, so no critical path can be derived. It is tempting because it does address resource assignments, and it would be correct when clarifying who owns each task rather than scheduling them.
- ✓
Gantt chart
Why this is correct
A Gantt chart plots tasks against a calendar timeline, showing dependencies, resource assignments and the critical path. When tasks slip, the bars and dependency links let the project manager recalculate the schedule and see which delays push the finish date.
- ✗
Kanban board
Why it's wrong here
A Kanban board visualises workflow stages and limits work in progress, but it does not store task durations or dependencies, so critical-path calculation is impossible. It is tempting because it tracks tasks and assignments visually, and it would be correct for managing continuous flow in an operational support team.

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 needs to track the start and end dates of tasks as well as dependencies. Which tool should be used?
easy- ✓ A.Gantt chart
- B.Control chart
- C.Fishbone diagram
- D.Pareto chart
Why A: A Gantt chart is the correct tool because it visually displays task start and end dates along a timeline, and it can explicitly show dependencies between tasks using arrows or linking lines. This makes it ideal for project scheduling and tracking progress against planned dates.
