Introduction:
PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) are project management tools used to plan, schedule, and control projects. While both PERT and CPM have similarities, there are certain differences between them.
Explanation:
The correct answer is option 'A': PERT is activity-oriented and CPM is event-oriented. This statement is not correct because PERT is event-oriented, not activity-oriented. Here is a detailed explanation of each statement:
a) PERT is activity-oriented and CPM is event-oriented:
- PERT (Program Evaluation and Review Technique) is event-oriented, where the focus is on determining the sequence of events or milestones in a project.
- CPM (Critical Path Method) is also event-oriented, where the focus is on identifying the critical path, which is the longest sequence of activities that determines the project duration.
b) In PERT, three time estimates are made, whereas in CPM only one time estimate is made:
- In PERT, three time estimates are made for each activity: optimistic time (O), pessimistic time (P), and most likely time (M). These estimates are used to calculate the expected time (TE) using the formula: TE = (O + 4M + P) / 6.
- In CPM, only one time estimate is made for each activity, which is the most likely time (M). This estimate is used to calculate the project duration.
c) In PERT slack is calculated whereas in CPM floats are calculated:
- In PERT, slack is calculated to determine the flexibility or float time for non-critical activities. Slack is the amount of time an activity can be delayed without affecting the project duration.
- In CPM, floats are calculated to determine the flexibility or float time for both non-critical and critical activities. Floats include total float, which is the amount of time an activity can be delayed without delaying the project, and free float, which is the amount of time an activity can be delayed without delaying the early start of its successor activities.
d) Both PERT and CPM are used for project situations:
- This statement is correct. Both PERT and CPM are widely used project management techniques to plan, schedule, and control projects. They help in identifying critical activities, determining project duration, allocating resources, and managing project risks.
Conclusion:
In conclusion, the statement that is not correct is option 'A': PERT is activity-oriented and CPM is event-oriented. PERT is event-oriented, and both PERT and CPM are used for project situations.
