Early finish of final task indicates

Critical path does not include any activity with
Slack
Critical Path Method helps to identify
the critical paths in the project networks
The path taking longest time through the network of activities is called
critical path
The critical path provides a wide range of
scheduling information useful in managing a project
CPM determines the requires sequence and construct a network diagram reflecting
the precedence relationships
Activity that has no predecessor is the
beginning activity
Activity that is predecessor to no other activity is the
ending activity

Critical Path
The shortest duration required to complete the project successfully
Slack
amount of time an activity can be delayed without impacting the overall project end date
On a critical path, we do not have
a slack, i.e slack = 0
When activity times vary,
a single time estimate may not be reliable
Critical paths do not have
SLACK TIME (In this example E is 31 - 28 making 3 week slack time
