Welcome back Rammy's — been a while! Let's pick up where you left off. To draw a Critical Path Method (CPM) network, we represent activities as nodes or arrows and dependencies as connections between them. The durations are assigned to each activity. Step 1: Identify start activities. Activities A and B have no predecessors, so they start from a common 'Start' node. Step 2: Draw activities and their immediate predecessors. • Activity C depends on A. • Activity D depends on A and B. This requires a merge point for A and B before D can start. • Activity E depends on C. • Activity F depends on D. • Activity G depends on E and F. This requires a merge point for E and F before G can start. Step 3: Assign durations to each activity. The durations are: A=4, B=6, C=3, D=5, E=4, F=3, G=2. The critical path network diagram is shown below. Each node represents an event, and each arrow represents an activity with its duration. Start A (4) Node 1 C (3) Node 2 E (4) Node 3 \\ Start B (6) Node 4 \\ Node 1 \\ Node 4 D (5) Node 5 F (3) Node 6 \\ Node 3 and Node 6 merge G (2) End Here is a more visual representation of the network: ` (Start) | |-- A (4 weeks) --> (Node 1) -- C (3 weeks) --> (Node 2) -- E (4 weeks) --> (Node 3) | | |-- B (6 weeks) --> (Node 4) -- D (5 weeks) --> (Node 5) -- F (3 weeks) --> (Node 6) | V (Node 7) -- G (2 weeks) --> (End) ` Note: Node 7 represents the merge point of E and F before G can start.
