# Is The Critical Path The Longest Path?

## How can the longest path determine the shortest project duration?

The longest path in a project network is the critical path.

The activities on the critical path have zero float or slack.

Therefore, the critical path results in the shortest total duration of the project..

## Why the critical path is the longest path in the network diagram?

Critical Path is the longest path through the project because that’s the only path with no (positive) float / wiggle room. Other (non-critical) paths on the schedule network diagram have (positive) float / wiggle room.

## What is the duration of the critical path?

The network path with longest total duration is the critical path! Critical path is the shortest duration required to complete the project successfully. In our example this is the second path: A -> B -> C -> D -> G -> H, which comes to 49 minutes.

## Can you have 2 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.

## Is the critical path the shortest path?

Yes, the critical path is the longest overall duration for the sequenced activities. It is not the shortest project duration and it is the shortest time possible to complete the project.

## Can a critical path change?

The critical path of a project will not remain static throughout its life, it can change during the course of project completion. Unforeseen circumstances sometimes may cause estimated duration of one or more activities to change.

## How do you identify a critical path?

Your critical path is the longest path from the first column through the lines showing prerequisites to the last column. It determines the project completion date because you must complete all tasks on the path within the estimated time or delay the project.

## Why is Critical Path the longest?

The time required to traverse each path is the sum of the times associated with all jobs on the path. The critical path (or paths) is the longest path (in time) from Start to Finish; it indicates the minimum time necessary to complete the entire project.

## Is Critical Path the longest or shortest?

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.
