Question

Arrange the following steps for applying the critical path method in the correct sequence :
A. Identification of all activities that the project require.
B. Network Diagram Construction
C. Critical Path Determination
D. Activity Duration Estimation
Choose the correct answer from the options given below :

• A. A, D, B, C
• B. A, B, D, C
• C. D, A, B, C
• D. B, A, D, C

Hint:

Any delay in an activity on the "Critical Path" will directly result in a delay of the entire project completion date.

Answer 1

The Correct Option is B

Concept: The Critical Path Method (CPM) is a step-by-step project management technique used to identify tasks on the critical path—the longest sequence of dependent activities that determines the shortest possible project duration.

Step 1: Project Definition.
The process begins with "Work Breakdown." You must first list every single task necessary to complete the project. Without a complete list of activities, the network cannot be formed. Therefore, A is the first step.

Step 2: Logic and Sequencing.
Once activities are identified, their dependencies must be established (which task must follow another). This is represented visually by constructing a network. Therefore, B follows A.

Step 3: Time Analysis.
After the structure of the project is mapped, you must estimate how long each individual activity will take to complete. Therefore, D follows B.

Step 4: Calculating the Path.
With the network and durations ready, you perform forward and backward passes to find the Earliest Start/Finish and Latest Start/Finish times. The path where Total Float is zero is the critical path. Therefore, C is the final step. The sequence is A-B-D-C.
