Gantt Chart Software: A Schedule Built on Real Structure
Orchesia generates your Gantt chart from your WBS and dependencies. Clear scope, identified critical path, timelines you can defend.
A Gantt built from nothing doesn't hold up.
It creates an illusion of control.
You start with an empty schedule
Most tools greet you with a blank Gantt to fill in. Tasks are entered without structure, durations estimated by intuition. The schedule is fragile from day one.
Your dates are constantly being rescheduled
Without explicit dependencies, every change forces manual rescheduling. The plan is behind before the project has even really started.
Your schedule doesn't reflect reality
Without a WBS and PERT upfront, the Gantt rests on implicit assumptions. It looks reassuring, but nobody truly believes the dates shown.
Gantt within a structured upfront planning approach
In Orchesia, the Gantt chart isn't a starting point. It's generated from a WBS and PERT already built. The schedule reflects project reality from day one.
Your Gantt is generated, not entered by hand
Once the WBS and dependencies are defined in the PERT, Orchesia automatically generates the Gantt chart. You don't have to enter dates one by one. The schedule flows from the structure.
Dependencies are respected automatically
Each task is positioned considering constraints defined in the PERT. The critical path is visible. You know exactly what can slip without impact and what is blocking.
L'IA au service de votre projet
Décrivez votre projet en une phrase : l'IA génère une structure WBS, prédit les tâches et propose les dépendances. Vous validez et ajustez en un clic. Vous gardez la main, l'IA accélère.
Adjust without rebuilding everything
When the project evolves, you modify the structure or dependencies. The Gantt recalculates automatically. No more manual rescheduling, no more ghost schedules.
A well-built Gantt chart is a schedule the team understands, the client believes, and you can defend.
A reliable Gantt isn't typed in.
It's generated from a solid structure.

PERT models dependencies between tasks and identifies the critical path. Gantt charts schedule tasks over time with dates. In Orchesia, you build the PERT first, then the Gantt generates automatically.
Yes. Without a WBS, the Gantt is a task list without structure. Durations are estimated by intuition and the schedule doesn't survive the first change.
Yes. The schedule is co-built with teams. Everyone sees the same Gantt in real time, with the same dependencies and milestones.
If the WBS and PERT are already built, the Gantt is generated in seconds. You can also start from scratch and let AI generate an initial structure from one sentence.
Yes, but Excel doesn't manage dependencies automatically, doesn't recalculate the schedule when a task slips, and doesn't support real-time collaboration. As soon as the project evolves, the file becomes a problem.
