The estimated expected (mean) time for project completion is 50 weeks, time management includes all the activities necessary to achieve the target date of delivery of the project. It includes the following activities: identification of activities, logical sequencing of activities, estimation of duration of activities, and preparation of the project schedule. For the preparation of the schedule we will see various methods such as resource leveling, simulation, and the critical chain method.
