Use a Gantt chart with the critical path method.
A Gantt chart shows when work happens. The critical path method explains which connected tasks control the project finish. Construction and installation schedules need both views when delays, resource pressure, and handover dates matter.
Start with real dependencies
Critical path analysis is weak when a schedule is only a list of tasks. Connect predecessor and successor relationships so the Gantt chart can show how one delayed task affects downstream work.
Use the Gantt chart for timing
The timeline helps users see where critical tasks sit inside the project window, where parallel work is happening, and which milestones may be exposed if dates move.
Review critical path before applying changes
When a task duration changes, planners should review affected tasks, finish-date impact, resource conflicts, and recovery options before committing the revision.
Do not treat critical path as a static label
The critical path can change after dependencies, dates, constraints, or resource assumptions are edited. Re-run schedule review after meaningful changes.
Common questions
Is a Gantt chart the same as the critical path method?
No. A Gantt chart is the visual timeline. The critical path method uses task relationships and durations to identify the sequence that controls the project finish.
Can a Gantt chart show critical path analysis?
Yes, if the schedule has enough structured task data: durations, dates, dependencies, milestones, and constraints.
Why does dependency quality matter?
Missing or incorrect dependencies can make the critical path misleading because the schedule does not know which work actually controls downstream tasks.
