1. Critical Path
In project management, the critical path
is the longest sequence of tasks that
must be completed to complete a
project. The tasks on the critical path are
called critical activities because if they’re
delayed, the whole project completion will
be delayed.

4. Critical Path
All projects will have at least one critical path.
All critical activities belong to a critical path.
A delay in any critical activity will extend the
project duration.
The noncritical activities can be delayed at least
1 day without lengthening the project duration.
Saving time in any noncritical activity does not
decrease at all the project's duration.
