PK0-005 Tools and Documentation Practice Question
A project manager is creating a visual timeline that displays tasks as horizontal bars, shows dependencies between tasks, and highlights the critical path. Which tool should the manager use?
⚠ Common exam trap
PK0-005 often tests tool-selection by feature description — candidates may pick 'network diagram' because it also shows dependencies, but only a Gantt chart combines horizontal task bars, a timeline, and critical-path highlighting.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Gantt chart
A Gantt chart is the standard project management tool that displays tasks as horizontal bars along a timeline, shows dependencies between tasks, and visually highlights the critical path. It directly matches all three requirements in the question.
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 it's wrong here
A network diagram shows tasks as nodes or arrows with logical dependencies, but it has no time axis, so it cannot display horizontal bars or a duration-scaled critical path. It is tempting because it does capture dependencies, yet the stem's bar-based timeline demands a Gantt chart.
- ✓
Gantt chart
Why this is correct
A Gantt chart plots tasks as horizontal bars against a calendar timeline, with dependency links between bars and critical path activities highlighted. It satisfies all three stem requirements: timeline bars, dependencies, and critical path emphasis.
- ✗
Milestone chart
Why it's wrong here
A milestone chart marks discrete events or checkpoints on a timeline; it does not render tasks as horizontal bars spanning duration, nor map dependencies or the critical path. It is tempting because milestones do appear on schedules, but bar length, dependency links and critical-path highlighting require a Gantt chart.
- ✗
Pareto chart
Why it's wrong here
A Pareto chart ranks causes by frequency on descending bars with a cumulative line, used for prioritising defects. It carries no schedule, duration or dependency data, so it cannot show task bars or a critical path. It is tempting because it is a bar chart, but its axis is category frequency, not time.
