PK0-005 Tools and Documentation Practice Question
Which project scheduling tool depicts activities as bars on a timeline, showing dependencies and milestones?
⚠ Common exam trap
PK0-005 often tests the confusion between Gantt charts and network diagrams; candidates must remember that Gantt charts use a timeline with bars, while network diagrams focus on dependencies without a time axis.
Answer choices
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 a project scheduling tool that depicts activities as horizontal bars along a timeline, with the length of each bar representing the duration of the activity. It also shows dependencies between activities and milestones, making it the correct answer.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Gantt chart
Why this is correct
A Gantt chart renders activities as horizontal bars positioned along a timeline, with bar length showing duration and links showing dependencies and milestones. This directly satisfies the stem's requirement for a tool depicting bars, dependencies and milestones.
- ✗
Burndown chart
Why it's wrong here
A burndown chart plots remaining work against time, not activity bars with dependencies and milestones. It is tempting because it tracks schedule progress, and it would be correct when the requirement is to show work remaining versus time during an iteration.
- ✗
Network diagram
Why it's wrong here
A network diagram shows activities as nodes or boxes linked by dependency arrows, without a calendar timeline or bars. It is tempting because it does model dependencies, and it would be correct when the requirement is to determine the critical path rather than depict bars against dates.
- ✗
Milestone chart
Why it's wrong here
A milestone chart marks significant points or events on a timeline, not activities as bars with dependencies. It is tempting because it uses a timeline, and it would be correct when the requirement is to highlight key dates or deliverables rather than show activity durations and dependencies.
