Most projects don’t fail in execution — they fail in planning, when nobody maps out what depends on what. This Timeline makes every dependency visible before it becomes a bottleneck.

What’s inside this Timeline template

• Colour-coded status — not started, in progress, on hold, and complete shown visually per task
• Baseline comparison — original planned dates shown alongside current dates to track schedule slip
• Summary row — automatic calculation of overall project completion percentage
• Export for client sharing — a clean version with internal notes hidden, ready to share in one click

How to use this Timeline template

1. Get access to the Gantt template and save a copy to your Drive.
2. List all project tasks in the task column, grouped by phase or workstream.
3. Enter start and end dates for each task — the Gantt bars generate automatically.
4. Assign an owner to each task and mark any dependencies in the notes column.
5. Update progress percentages weekly — the chart reflects changes immediately.

Why Google Sheets for Timeline?

The best project timeline is the one the whole team trusts. A Google Sheets Gantt chart updated by the people actually doing the work — rather than a PM re-entering data from emails — stays more accurate than any dedicated tool.

Frequently asked questions

Can I share this with clients or stakeholders?

Yes. Share the link with view-only access for external parties. They see the same live timeline you do without being able to edit the underlying data.

Does the chart update automatically when I change dates?

Yes. Edit the start or end date of any task and the Gantt bar repositions immediately. No manual chart adjustments required.

Can I show dependencies between tasks?

The template includes a dependency notes column. For visual dependency lines, use the conditional formatting guide in the instructions tab to add connecting markers between linked tasks.
