“A project is a series of activities directed to accomplishment of a desired objective.”

Project

Plan your work first…..then work your plan

Each event has two important times associated with it :

Earliest time , Te , which is a calendar time when a event can occur when all the predecessor events completed at the earliest possible times

Latest time , TL , which is the latest time the event can occur without delaying the subsequent events and completion of project.

Difference between the latest time and the earliest time of an event is the slack time for that event
