Assignment Solution: Project Management for Learning Management System
---
1. Introduction
Project management is an essential discipline that involves planning, executing, monitoring, and controlling projects to meet specific goals. In this assignment, we will create a structured overview of a project related to developing a Learning Management System (LMS) like Moodle. This includes developing a network diagram, calculating the critical path, creating a Work Breakdown Structure (WBS), an Activity Diagram, and a Domain Model Class Diagram.
---
2. Network Diagram Creation
To represent the activities involved in the project, we need to create a network diagram. Below is a hypothetical representation of the project's activities:
| Activity | Duration (Days) | Predecessors |
|----------|-----------------|---------------|
| 1. Gathering Data | 10 | - |
| 2. Interview | 5 | 1 |
| 3. Analyze Data | 5 | 2 |
| 4. Define User Requirements | 5 | 3 |
| 5. Define System Requirements | 5 | 4 |
| 6. Develop Use Case Model | 10 | 5 |
| 7. Develop Class Diagram | 8 | 6 |
| 8. Develop State Machine Diagram | 8 | 7 |
| 9. Develop Activity Diagram | 8 | 8 |
| 10. Develop Sequence Diagram | 6 | 9 |
| 11. Develop ERD | 6 | 10 |
| 12. Prepare Analysis Report | 7 | 11 |
| 13. Design Database | 10 | 12 |
| 14. Design Software Architecture | 8 | 13 |
| 15. Develop Software | 20 | 14 |
| 16. Testing Software | 10 | 15 |
| 17. Fix Problems | 8 | 16 |
| 18. Prepare Final Report | 5 | 17 |
| 19. Deployment | 5 | 18 |
Network Diagram
The network diagram is created by connecting the activities based on their predecessors. Each activity is represented by a node, and arrows denote the direction of flow from predecessor to successor.

3. Earliest Start, Earliest Finish, Latest Start, Latest Finish, and Slack Calculation
Using the forward and backward pass methods, we can calculate the Early Start (ES), Early Finish (EF), Late Start (LS), Late Finish (LF), and Slack (Total Float) for each activity.
| Activity | Duration | ES | EF | LS | LF | Slack |
|----------|----------|----|----|----|----|-------|
| 1 | 10 | 0 | 10 | 0 | 10 | 0 |
| 2 | 5 | 10 | 15 | 10 | 15 | 0 |
| 3 | 5 | 15 | 20 | 15 | 20 | 0 |
| 4 | 5 | 20 | 25 | 20 | 25 | 0 |
| 5 | 5 | 25 | 30 | 25 | 30 | 0 |
| 6 | 10 | 30 | 40 | 30 | 40 | 0 |
| 7 | 8 | 40 | 48 | 40 | 48 | 0 |
| 8 | 8 | 48 | 56 | 48 | 56 | 0 |
| 9 | 8 | 56 | 64 | 56 | 64 | 0 |
| 10 | 6 | 64 | 70 | 64 | 70 | 0 |
| 11 | 6 | 70 | 76 | 70 | 76 | 0 |
| 12 | 7 | 76 | 83 | 76 | 83 | 0 |
| 13 | 10 | 83 | 93 | 83 | 93 | 0 |
| 14 | 8 | 93 | 101 | 93 | 101 | 0 |
| 15 | 20 | 101 | 121 | 101 | 121 | 0 |
| 16 | 10 | 121 | 131 | 121 | 131 | 0 |
| 17 | 8 | 131 | 139 | 131 | 139 | 0 |
| 18 | 5 | 139 | 144 | 139 | 144 | 0 |
| 19 | 5 | 144 | 149 | 144 | 149 | 0 |
Explanation of Key Terms
- Earliest Start (ES): The earliest time an activity can start after all its predecessors have completed.
- Earliest Finish (EF): The earliest time an activity can finish, calculated as ES + duration.
- Latest Start (LS): The latest time an activity can start without delaying the project.
- Latest Finish (LF): The latest time an activity can finish without delaying the project, calculated as LS + duration.
- Slack: The total float is the total time that you can delay a task without delaying the project. If slack is zero, the task is critical.

4. Defining the Critical Path
The Critical Path is the longest path through the project with the least amount of slack. It indicates the minimum completion time.
In our network, the critical path consists of activities with zero slack. For this scenario, all activities are on the critical path: 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8 -> 9 -> 10 -> 11 -> 12 -> 13 -> 14 -> 15 -> 16 -> 17 -> 18 -> 19.
Total Project Duration: 149 days, which extends beyond our expected project time of 85 days. Further analysis will be required to optimize the plan.

5. Work Breakdown Structure (WBS)
We will utilize a phased Work Breakdown Structure for the LMS project that divides the project based on distinct phases:
1. Initiation
- Gathering Data
- Interview
2. Planning
- Analyze Data
- Define User Requirements
- Define System Requirements
3. Design
- Develop Use Case Model
- Develop Class Diagram
- Develop State Machine Diagram
- Develop Activity Diagram
- Develop Sequence Diagram
- Develop ERD
4. Implementation
- Prepare Analysis Report
- Design Database
- Design Software Architecture
- Develop Software
5. Testing and Deployment
- Testing Software
- Fix Problems
- Prepare Final Report
- Deployment

6. Activity Diagram
The Activity Diagram for the LMS project will graphically represent the workflow towards the final system.
```plaintext
[Start] --> (Gather Data) --> (Interview) --> (Analyze Data) --> (Define User Requirements) --> (Define System Requirements) --> (Develop Use Case Model) --> (Develop Class Diagram) --> (Develop State Machine Diagram) --> (Develop Activity Diagram) --> (Develop Sequence Diagram) --> (Develop ERD) --> (Prepare Analysis Report) --> (Design Database) --> (Design Software Architecture) --> (Develop Software) --> (Testing Software) --> (Fix Problems) --> (Prepare Final Report) --> (Deployment) --> [End]
```

7. Domain Model Class Diagram
The Domain Model Class Diagram for the LMS would typically include:
- Classes such as:
- User (attributes: userId, name, email)
- Course (attributes: courseId, title, description)
- Enrollment (attributes: enrollmentId, userId, courseId, status)
- Resource (attributes: resourceId, type, courseId)
Associations among classes showing relationships, e.g., "User" enrolls in "Course."

Conclusion
Through careful planning and representation via network diagrams, WBS, activity diagrams, and class diagrams, we can streamline the project management process. Identifying the critical path gives insights into activities impacting project timeframes, while the Work Breakdown Structure organizes project phases effectively.
