What is a Gantt Chart? Bar Chart Timeline for Project Tasks
Which project management tool displays project tasks against a timeline and shows dependencies?
Quick Answer
The correct answer is the Gantt chart. This tool is the right choice because it visually maps project tasks along a horizontal timeline, using bars to represent task duration and arrows or lines to show dependencies between tasks, making it the only option that combines a timeline view with dependency tracking. On the CompTIA Project+ PK0-005 exam, this concept tests your ability to distinguish between scheduling tools; a common trap is confusing the Gantt chart with a PERT chart, which focuses on network logic and critical path without the same timeline bar visualization. To remember, think of the Gantt chart as a bar chart timeline that literally shows how tasks “depend” on each other through connecting lines—if you see bars and arrows on a timeline, it’s a Gantt chart.
⚠ Common exam trap
CompTIA often tests the distinction between a Gantt chart and a network diagram, where candidates mistakenly choose the network diagram because it shows dependencies, but they overlook that the question specifically requires a timeline display, which only the Gantt chart provides.

Correct answer & explanation
✓
Gantt chart
A Gantt chart is the correct project management tool because it visually maps project tasks along a horizontal timeline, with bars representing task duration and arrows or lines indicating dependencies between tasks. This allows project managers to see the sequence of work, identify critical paths, and track progress against scheduled dates, which is exactly what the question describes.
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 plots tasks as horizontal bars against a calendar timeline, with linking arrows showing finish-to-start dependencies between activities. This directly satisfies the stem's requirement to display tasks against a timeline while exposing the dependency relationships that govern scheduling.
- ✗
Calendar
Why it's wrong here
A calendar maps tasks to dates but cannot express finish-to-start relationships or a critical path, so dependencies remain invisible. Calendars are the right tool for communicating milestones and deadlines to stakeholders, not for dependency-driven scheduling.
- ✗
Network diagram
Why it's wrong here
A network diagram shows task dependencies as nodes and arrows but omits the calendar timeline, so duration and schedule position are lost. It is the correct choice when the goal is analysing dependency logic and float, not displaying tasks against dates.
- ✗
Work breakdown structure
Why it's wrong here
A work breakdown structure decomposes deliverables into hierarchical components; it carries no time axis or dependency links, so it cannot display tasks against a timeline. It is tempting because it does map all project work, and would be the right artefact when the goal is scope decomposition rather than scheduling.
