Question

For the following schedule, draw the node network, perform the CPM calculations, mark the critical path, and complete the table.

Please use the format in screenshot 24 exactly as it requires.

**Chapter 4 Exercises**

1. For the following schedule, draw the node network, perform the CPM (Critical Path Method) calculations, mark the critical path, and complete the table.

| Activity | Duration | IPA | ES | EF | LS | LF | TF | FF |
|----------|----------|-----|----|----|----|----|----|----|
| A | 3 | – | | | | | | |
| B | 7 | A | | | | | | |
| C | 4 | A | | | | | | |
| D | 5 | B | | | | | | |
| E | 8 | B, C| | | | | | |

- **Activity**: Represents tasks or operations to be completed.
- **Duration**: The time required to complete each activity.
- **IPA (Immediate Predecessor Activity)**: Activities that must be completed before the current activity starts.
- **ES (Earliest Start)**: The earliest time an activity can start after its predecessor activities are complete.
- **EF (Earliest Finish)**: The earliest time an activity can finish.
- **LS (Latest Start)**: The latest time an activity can start without delaying the project.
- **LF (Latest Finish)**: The latest time an activity can finish without delaying the project.
- **TF (Total Float)**: The total time an activity can be delayed without affecting the project completion.
- **FF (Free Float)**: The time an activity can be delayed without delaying the early start of any subsequent activities.

**Question 1**

**Instructions and Diagram Explanation:**

The concepts illustrated in this diagram are crucial for project management tasks such as scheduling and tracking. The framework here is a graphical representation of project activities and their dependencies, often used in critical path method (CPM) analysis. Follow these key notes below for guidance in filling out the activity nodes:

**Yellow Format Guide:**

- **ES (Earliest Start)**
- **TF (Total Float)**
- **EF (Earliest Finish)**

- **LS (Latest Start)**
- **FF (Free Float)**
- **LF (Latest Finish)**

### Diagram Components:

- **Main Nodes**: Each node depicts a project activity with placeholders to input timelines and float for calculations.
- **Activity**: The node labeled "A" signifies the start or an individual task in the process.
- **Arrow Directions**: They indicate sequences and dependencies between tasks.
- **Project Finish**: Marked in red, this node represents the project's completion point.

### Tips for Using the Diagram:

1. **Fill in the Details**: For each activity, correctly populate the fields in each node using the format highlighted in yellow.
2. **Understand Dependencies**: Arrows show which activities are prerequisites; tasks leading up to the "Project Finish" must be completed.
3. **Calculate Floats**: Recognize how total float and free float can affect your scheduling and flexibility.

Leverage this format for effective project management and strategizing timelines for completion.
