Gantt charts: a practical guide to planning

A Gantt chart places tasks against a timeline. It helps you see when work starts and ends, what overlaps, and which steps need to happen first.

What does a Gantt chart help you see?

A task list tells you what to do. A Gantt chart adds when to do it. Compare the bars to spot overlapping work, waiting periods, and handoffs that may affect the schedule.

When is it useful?

Projects with a deadline

Use it to work back from a release, event, or submission date and discuss whether the available time is realistic.

Work involving several people

Show who handles each task and review overlapping assignments. A long bar is elapsed time, not a measure of how busy a person is each day.

Personal plans

Study, moving, and travel preparations can also benefit from a small timeline. Keep the number of tasks manageable.

Gantt chart or flowchart?

Use a Gantt chart to discuss dates and durations. Use a flowchart to describe the order of actions and conditional branches. For a release project, keep the schedule in a Gantt chart and describe approval or retry rules in a flowchart.

Start with a draft, then update it

A schedule is a working plan, not a guarantee. Start with a small draft, agree on assumptions with the people involved, and update the dates when you learn more. Preserve the original plan separately if you need to compare it with later changes.
