What is difference between PERT and CPM?

PERT is that technique of project management which is used to manage uncertain (i.e., time is not known) activities of any project. … CPM is that technique of project management which is used to manage only certain (i.e., time is known) activities of any project.

What is slack time in CPM?

The slack time for an activity is the time between its earliest and latest start time, or between its earliest and latest finish time. Slack is the amount of time that an activity can be delayed past its earliest start or earliest finish without delaying the project.

What is difference between slack and float?

That means that slack is referring to the amount of time that an activity can start later than originally planned and float is about the time when an activity takes longer than originally planned. … Total float is the amount of time that an activity can be delayed without delaying the completion of the project.
