Understanding CPM vs. PERT: How Do These Project Management Techniques Differ?

Hi Friends,

Very good day! I want to know more about two management techniques - CPM & PERT - and what is the difference between the two. These are used to define and coordinate various activities of a project and successfully accomplish the objectives on time.

CPM analysis is activity-oriented, focusing on the start and completion of events rather than activities, whereas PERT is event or job-oriented.
