PK0-005 Tools and Documentation Practice Question
Which project scheduling tool displays tasks as horizontal bars on a timeline, shows dependencies between tasks, and can highlight the critical path?
⚠ Common exam trap
The trap is confusing Gantt charts with network diagrams or milestone charts. Candidates might choose network diagram because it shows dependencies, but it does not use horizontal bars on a timeline. The key is to remember that Gantt charts are specifically for timeline-based scheduling with bars.

Correct answer & explanation
✓
Gantt chart
A Gantt chart is a project scheduling tool that displays tasks as horizontal bars on a timeline, shows dependencies between tasks, and can highlight the critical path. It provides a visual representation of the project schedule, making it easy to see task durations, start and end dates, and overlaps.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Kanban board
Why it's wrong here
Kanban boards visualise workflow states as cards moving through columns, with no time axis, duration bars or dependency links, so critical-path calculation is impossible. They suit continuous-flow or agile delivery tracking where limiting work in progress matters rather than schedule sequencing.
- ✗
Network diagram
Why it's wrong here
A network diagram depicts nodes and logical links, such as task dependencies or infrastructure topology, without horizontal bars against a timescale. It would be correct for mapping relationships, whereas the stem requires bars, durations and critical-path highlighting.
- ✓
Gantt chart
Why this is correct
A Gantt chart renders tasks as horizontal bars against a calendar timeline, draws dependency links between them, and can shade or flag critical path activities. It uniquely satisfies all three stem requirements: timeline bars, dependencies and critical path highlighting.
- ✗
Milestone chart
Why it's wrong here
Milestone charts mark only key dates or deliverables as single points, so they cannot render duration bars, dependency arrows or critical-path highlighting. They suit executive progress reporting where only completion checkpoints matter, not the activity sequencing this scheduling question demands.
