Question

All projects despite the size of the project, require some degree of planning. Critical Path Method (CPM) is a technique that can be used to plan projects effectively. (Slack and Brandon-Jones, 2019). Given below is a list of activities, predecessors and the duration of a project. Project Activities Activity ID : A B C D E F G Duration (In Days) : 3 4 3 3 3 1 2 Precedent(s): - - A A B CDE DE Using the above information a. Develop the network diagram using Activity On Arrow (AOA) method and identify the critical path of the project. Determine the project duration. You may develop the network diagram manually and paste it as a figure to your portfolio. You are responsible for a clear presentation.

Answer 1

Use the Critical Path Method to create an Activity On Arrow network diagram with the given project activities, identify the critical path, and calculate the project duration.

Step-by-step explanation:

The question involves using the Critical Path Method (CPM) to plan a project by developing a network diagram using the Activity On Arrow (AOA) method and identifying the critical path to determine the project's duration. To apply the CPM, one needs to analyze each activity, its predecessor(s), and the duration.

Step 1: Construct the network diagram by placing activities on arrows and connecting them from start to end. Begin with activities without predecessors and connect subsequent activities based on given precedence relationships.

Activities A and B, without predecessors, can start immediately. Activity C follows A, and Activity D also follows A. Activity E follows B, while Activity F depends on C, D, and E. Activity G follows D and E.

Step 2: After illustrating the network, identify the longest path through the network, which is the project's critical path. Calculate the duration by summing the times of activities in the critical path, determining the overall project duration.
