Click to see complete answer. Herein, can a project have multiple critical paths?
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)
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.
