How to View the Critical Path in Project Insight – Project Insight Help Center

Project Insight uses intelligent scheduling and standard critical path methodology to calculate which tasks can affect the project end date. You can identify critical tasks from the Task List, highlight them in red on the Gantt chart, manually mark a task as always critical, or use the Critical Paths add-on for a more detailed view.

Best for: Project managers, schedulers, and PMO teams that need to identify which tasks require the closest attention because a delay could move the project completion date.

What is the critical path?

The critical path is the sequence of scheduled tasks that determines when the project can finish. A critical task has no available slack, meaning that moving or extending it can move the project end date.

A task with available slack may be delayed without changing the final project date. That task is not currently critical.

Project Insight does this by using task dates, durations, and relationships to calculate which tasks directly influence the project completion date.

Does Project Insight calculate the critical path automatically?

Yes. Project Insight intelligent scheduling automatically calculates the critical path using standard project management critical path methodology.

As task dates, durations, or relationships change, the critical path may also change.

How do I identify critical tasks on the Task List?

Open the project Task List.
Add the Critical Task column to the view.
Review the indicator shown for each task.

Tasks displaying the red exclamation-point indicator are critical. Tasks without the indicator are not currently on the calculated critical path.

How do I show the critical path on the Gantt chart?

Open the project Gantt chart.
Expand the task structure as needed.
Open Filters.
Select More Filters.
Enable the option to show critical tasks in red.
Refresh the Gantt chart.

Project Insight displays critical tasks in red so you can visually trace the tasks that influence the project end date.

Why are some tasks not critical?

A task is not critical when it has enough slack to move or extend without changing the project end date.

For example, if a task can be delayed several days and the project still finishes on the same date, that task is not currently critical.

In short, a task becomes critical when a delay to that task would delay the project.

What happens if I move a critical task?

Moving a critical task earlier or later can change the project completion date because the task has no available slack.

Project Insight recalculates the connected schedule based on the task’s new position and its relationships with other tasks.

Can I manually mark a task as critical?

Yes. Project Insight includes an Always Critical option for tasks that you want treated as critical even when the calculated schedule shows available slack.

Open the task in the full edit screen.
Open the Advanced options.
Enable Always Critical.
Save the task.

The task will then appear as critical even if it would not otherwise be part of the calculated critical path.

When should I use Always Critical?

Use Always Critical when a task needs to be highlighted and managed as critical for business or project-control reasons, even though it has schedule slack.

Because this setting overrides the calculated result, use it only when the task should intentionally be treated as critical.

What is the Critical Paths add-on?

The Critical Paths add-on provides a separate view for reviewing the leading critical paths within a project plan.

This can be more useful in a large or complex project where several connected paths may be influencing important dates.

[Product detail placeholder: Confirm the current number of critical paths the add-on can display.]

How do I use the Critical Paths add-on?

Confirm that the Critical Paths add-on is available and enabled.
Open the Critical Paths view for the project.
Review the critical paths identified by Project Insight.
Use the available filters when you need to narrow the analysis.

Project Insight does this by separating and displaying the most important task sequences that influence the schedule.

Can I filter a critical path between milestones?

Yes. The Critical Paths tool includes start and end filters that can be used to review the critical path between selected milestones.

This can help you focus on the schedule risk within one phase or section of a larger project instead of reviewing the entire plan.

Which critical path view should I use?

Use the Critical Task column when you need a simple task-by-task indicator on the Task List.

Use the Gantt chart when you want to see the critical path visually across the project timeline.

Use the Critical Paths add-on when you need to review multiple important paths or focus on the path between milestones in a larger project.

What does critical path analysis help a team accomplish?

Critical path analysis helps teams understand which tasks have the greatest effect on the project finish date.

It can help project managers:

Prioritize tasks that cannot slip without affecting completion
Identify where schedule attention is most important
Understand why some tasks have flexibility and others do not
Review schedule risk visually on the Gantt chart
Focus on critical work between major milestones

In short, Project Insight calculates and displays the critical path so teams can focus on the work most likely to affect the project deadline.

What should I check when reviewing the critical path?

Confirm that task relationships are set correctly.
Review whether task durations accurately reflect the work.
Check whether noncritical tasks have enough slack to absorb a delay.
Refresh the Gantt chart after changing critical-path display options.
Use Always Critical only when a manual override is intentional.
Recheck the critical path after schedule changes.

What are common mistakes when reviewing the critical path?

Assuming every task in a waterfall plan is automatically critical
Confusing an important task with a task that has no schedule slack
Looking only at task priority instead of schedule relationships
Forgetting to enable critical-task coloring on the Gantt chart
Manually marking tasks Always Critical without a clear reason
Assuming the critical path will remain unchanged after the schedule moves

What makes a task critical?

A task is critical when it has no available slack and moving it would affect the project end date.

Can I see critical tasks in the Task List?

Yes. Add the Critical Task column and look for the red exclamation-point indicator.

Can I highlight critical tasks in red?

Yes. Enable the option to show critical tasks in red from the Gantt chart’s More Filters area.

Can a task be important without being on the calculated critical path?

Yes. A task may be important for business reasons while still having schedule slack. Use Always Critical only when you want to override the calculated result and display it as critical.

Can I review the critical path between two milestones?

Yes. Use the start and end filters in the Critical Paths add-on to focus on the path between selected milestones.
