The Critical Path Method (CPM) is the tool to identify the critical path(s) of a project. To identify a critical path, you need to estimate the Earliest Start, Earliest Finish, Late Start, and Late Finish of each activity or task of the project. Which of the followings best describes Earliest Finish (EF)? Earliest time at which an activity can be completed Latest time at which an activity can start to prevent delays in the project completion Earliest time at which an activity can start, assuming all predecessor tasks have been completed Latest time by which an activity has to be finished to prevent delays in the project completion
