An online Gantt chart that plans
In Etapero the Gantt chart is a planning tool, not a picture. It is built from the work breakdown, works out dates from dependencies and the production calendar, and shows at once what will move the project end date.
No sign-up needed.
Dependencies drive the dates
Set a predecessor and the successor’s dates follow. All four dependency types are supported — finish-to-start, start-to-start, finish-to-finish and start-to-finish — with lead and lag in working days.
Dates follow a production calendar with holidays and working weekends, so a duration in days means working days.
Critical path and float
Work on the critical path is highlighted: any delay there moves the end of the project. Work with little float is highlighted too — it is what may turn critical tomorrow.
Baseline, forecast and scenarios
- A baseline records the approved dates, and the forecast’s slip against it shows on every row.
- Goals and milestones have their own timeline: baseline date versus current forecast.
- “What if” scenarios show how dates would change if work moved — without touching the plan.
- Weeks, months or quarters, full-screen mode and PDF export of the plan.
A plan you edit like a spreadsheet
Next to the chart is the work breakdown, edited like a spreadsheet: type in cells, paste rows, move with the keyboard, undo and redo. Task statuses colour the Gantt bars, so the state of the plan is visible without a report.
