# View project milestones and critical path

Tasks that are milestones or part of the critical path may require more attention from project managers, because whether these tasks can be reached or completed on time determines whether the project's scheduled duration needs to be extended.

In this topic:

## View project milestones

You can view project milestones from either the Milestone Summary portlet or the project work plan.

### From Milestone Summary portlet

Prerequisite:

- The Milestone Summary portlet is added to the Summary tab of the project details page.
- If the project's Project Fields policy is set to track major milestones only, the Milestones portlet only lists major milestones. Otherwise, all milestones are displayed. However, the number of milestones to display is restricted by the Display Settings for milestones in the Project Overview Layout policy. For details see Project Overview Layout policy and Project Fields Policy.

Milestones that have a red exclamation mark in the front of the name have exceptions. Click the milestone name link to open the task details page to view exception details.

Note: To avoid performance issues, the Milestone Summary portlet in the Summary tab displays 200 milestones at the maximum. If you want to view the full list of milestones, go to the work plan.

### From the work plan

- Milestones in any view of the work plan has a black diamond indicator in the front of the task name.
- To view only milestones in the work plan, use the Tasks that are milestonefilter in any view other than the Quick view of the work plan.

## View project critical path

This section describes how to view project critical path.

### Overview of project critical path

If a task's slack, that is the amount of time the task can be delayed from its start without delaying the project, is less than or equals to the specified critical path threshold, the task is identified as part of the project critical path.

Critical path threshold is set in the project's Scheduling policy. See Scheduling policy.

PPM calculates a task's slack as described in How PPM calculates task's slack.

### View project critical path

Use either of the options described in the table below to show project critical path in the work plan:

Option | Details
--- | ---
Add the Critical Path Tasks Indicators column in the work plan | This method is applicable to all the work plan views except the Quick view. To add the Critical Path Tasks Indicator column: In the work plan, click Actions > Configure Indicator Columns. Select the option Mark Tasks On Critical Path, and click OK. Critical path tasks are indicated with a red flag in this column.
Highlight critical path in the gantt chart of the work plan Gantt view | This method is applicable to the work plan Gantt view only. To highlight critical path in the gantt chart: In the work plan Gantt view, click Actions > Configure Gantt. Select the option Highlight Critical Path, and click OK.
