PK0-005 Practice Question: A project manager is using a Gantt chart to track…
A project manager is using a Gantt chart to track progress. Which tool would BEST complement the Gantt chart to show task dependencies and the critical path?
⚠ Common exam trap
Watch out — candidates often confuse the Work Breakdown Structure (WBS) with a schedule tool, mistakenly thinking it shows task order, when in fact the WBS is a deliverable-oriented decomposition and does not represent dependencies or the critical path.

Correct answer & explanation
✓
Network diagram
A network diagram (e.g., activity-on-node or PERT chart) is the best complement to a Gantt chart because it explicitly maps task dependencies (finish-to-start, start-to-start, etc.) and calculates the critical path using forward and backward pass methods. While a Gantt chart shows progress over time, it does not inherently display the logical relationships between tasks or the float/slack values needed to identify the critical path.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Network diagram
Why this is correct
A network diagram clearly shows dependencies and critical path.
- ✗
Change log
Why it's wrong here
Change log tracks changes, not dependencies.
- ✗
Work breakdown structure
Why it's wrong here
A WBS breaks down work but does not show dependencies.
- ✗
Risk register
Why it's wrong here
Risk register unrelated to dependencies.
