Show Hint
- A and B only
- A and D only
- B and C only
- C and D only
The Correct Option is C
Solution and Explanation
Step 1: Difference between PERT and CPM.
- PERT (Program Evaluation and Review Technique) is an event-oriented method, focusing on uncertainties in project time.
- CPM (Critical Path Method) is an activity-oriented method, focusing on planning, scheduling, and control of time and cost.
Step 2: Checking each statement.
- (A) Event-oriented → This is true for PERT, not CPM. Hence, incorrect.
- (B) Activity-oriented → Correct for CPM.
- (C) Time and cost are controlling factors → Correct, CPM deals with cost and time optimization.
- (D) Time alone is the controlling factor → Incorrect, because CPM considers both time and cost.
Step 3: Conclusion.
The correct statements are B and C only.
