Does MS Project calculate critical path?

The critical path is constantly calculated by Microsoft Project and can change as tasks are modified or updated. The Tracking Gantt Chart, described later in this chapter, includes the critical path by default. You can also modify the standard Gantt Chart view to see which tasks are on the critical path in a project.

You can have more than one critical path in a project, so that several paths run concurrently. This can be the result of multiple dependencies between tasks, or separate sequences that run for the same duration. In fact, the activities on the critical path are not always the most important parts of the project.

Also, why is there no critical path? When you are collecting tasks for the critical path, they must have zero float. But if the tasks do have some float, then they go on the non-critical path, which means if this task is delayed the project can still finish on time.

Likewise, how does MS Project calculate slack?

Use the Detail Gantt view to find slack (float)

  1. Click View > Other Views > More Views.
  2. In the Views list, double-click Detail Gantt.
  3. Click View > Tables> Schedule.
  4. Click a task and view its slack values in the Free Slack and Total Slack fields.

What is Project Critical Path?

In project management, a critical path is the sequence of project network activities which add up to the longest overall duration, regardless if that longest duration has float or not. This determines the shortest time possible to complete the project. There can be 'total float' (unused time) within the critical path.
