The drawing

What an online Gantt chart is.

An online Gantt chart is a project schedule that puts tasks on a time axis. Each task is a bar with a start date and end date, so you can see its duration and where it overlaps with other work.

Lanes group the bars by team or workstream, such as planning, engineering or quality. Milestones mark dates that matter but do not take time, such as an approval, a pilot acceptance or a launch.

FAQ

Common questions

What is a Gantt chart?

A Gantt chart is a project schedule that displays tasks as bars against a timeline. The bar length shows the task duration, while milestones mark important dates such as approvals or releases.

How do I create a Gantt chart online?

Describe the project, the tasks, their start and end dates, and the teams or workstreams that own them. Add milestones for important decision or delivery dates, then refine the schedule with follow-up edits.

What information should I include in a Gantt chart?

Include task names, dates, work lanes and milestones. Mention which work can overlap and any approvals or deadlines that must be visible.

Why use lanes in a Gantt chart?

Lanes group tasks by team or workstream. They make responsibility, parallel work and handoffs easier to read than one long list of bars.

Can I revise an online Gantt chart?

Yes. Ask to add a task, change a date, move work to another lane or add a milestone, and the schedule can be updated.
