Question
What is true about the PERT/CPM technique for creating a suitable schedule for the given project1. It is based on the work breakdown structure.2. The early start and Early finish times are obtained while calculating backwords.3. Slack time for a task not falling in the critical path cannot be zero.4. Slack time for all tasks falling in the critical path must be zero.5. The late finish of the project is the same time with which the last task finishes at the earliest possible time.Group of answer choices1, 2, and 41 and 31, 3, and 53 and 5
Solution
The correct group of answer choices is 1, 3, and 5.
Here's why:
-
True: The PERT/CPM technique is indeed based on the work breakdown structure. This structure breaks down the project into smaller, manageable tasks, which are then used in the PERT/CPM technique to create a suitable schedule.
-
False: The early start and early finish times are obtained while calculating forwards, not backwards.
-
True: Slack time for a task not falling in the critical path can indeed be more than zero. This is because these tasks can be delayed without delaying the project.
-
False: While it's true that tasks on the critical path should ideally have zero slack time, in reality, this may not always be the case due to unforeseen circumstances or changes in the project.
-
True: The late finish of the project is indeed the same time with which the last task finishes at the earliest possible time. This is because any delay in the last task will delay the entire project.

A CPM/PERT project network with probabilistic activity times includes an activity with a most likely time of 18 days, an optimistic time of 5 days, and a pessimistic time of 23 days. The mean time for this activity is (round to the nearest whole number)
A list of differences between PERT and CPM is given below. Choose the option that is incorrectly matched with either PERT or CPM. CPM categorises activities into critical and non-critical activities whereas PERT does not.In PERT, the duration of activities is accurate and definite whereas in CPM it is not.PERT is a probabilistic management tool whereas CPM is a deterministic management tool. PERT is suitable for defense and R&D projects where activity time cannot be reliably predicted whereas CPM is suitable for problems in industrial settings, plant maintenance and civil construction projects.
