Project Network
1. **Stating the problem:** We need to determine which network diagram correctly represents the project activities and their immediate predecessors for Oak Dale LLC.
2. **Understanding the data:** The activities and their immediate predecessors are:
- A: no predecessor
- B: no predecessor
- C: no predecessor
- D: predecessor A
- E: predecessor B
- F: predecessor C
- G: predecessor D
- H: predecessors E and F
3. **Rules for network diagrams:**
- Activities with no predecessors start the network.
- Each activity must be connected to its immediate predecessor(s).
- Activities with multiple predecessors (like H) must have arrows coming from all those predecessors.
4. **Constructing the network:**
- Start with A, B, and C as initial nodes.
- D follows A.
- E follows B.
- F follows C.
- G follows D.
- H follows both E and F.
5. **Conclusion:** The correct network diagram is the one that shows:
- Three starting nodes A, B, C.
- Arrows from A to D, B to E, C to F.
- Arrow from D to G.
- Arrows from E and F converging to H.
This matches the project dependencies exactly.
