Quizplus · Accepted Answer

The purpose of the backward pass in the CPM technique is to determine the latest time each activity can start and finish, which is option D. This is done by working backwards through the network, starting from the latest event time determined during the forward pass. Option A is incorrect as the backward pass is focused on calculating the latest times, not reviewing the precedence relationships. Option B is incorrect as slack time is calculated during the forward pass. Option C is incorrect as the earliest times are determined during the forward pass.
