Mastering the Total Network: A Guide to Project Planning & Scheduling
In the realm of project planning and scheduling, understanding the concept of the "Total Network" is crucial for success. It serves as the backbone of effective project management, enabling teams to visualize, analyze, and control the complex interplay of activities within a project.
What is a Total Network?
A Total Network, also known as a Project Network Diagram, is a comprehensive graphical representation of all project activities. It depicts the sequence of tasks, their dependencies, and the estimated duration for each activity. Essentially, it's a visual blueprint of the entire project, providing a clear understanding of the workflow and critical path.
Components of a Total Network:
- Nodes: Represent individual activities within the project.
- Arrows: Connect nodes, indicating the sequence of activities and their dependencies.
- Duration: Each node is assigned an estimated time to complete the corresponding activity.
- Critical Path: The longest path through the network, identifying the sequence of activities that cannot be delayed without jeopardizing the project deadline.
Benefits of Using a Total Network:
- Clear Visualization: A Total Network provides a visual overview of the entire project, making it easy to understand the relationships between tasks and their dependencies.
- Effective Communication: It facilitates seamless communication between project stakeholders, ensuring everyone is on the same page regarding project progress and potential challenges.
- Resource Allocation: The network helps optimize resource allocation by highlighting critical activities and identifying potential bottlenecks.
- Risk Management: It allows for the identification of potential risks and the development of mitigation strategies.
- Schedule Control: By tracking progress against the network, project managers can identify schedule deviations and take corrective actions.
Constructing a Total Network:
- Identify Activities: Define all tasks required to complete the project.
- Sequence Activities: Determine the order in which activities must be performed, considering dependencies.
- Assign Durations: Estimate the time required to complete each activity.
- Construct the Network: Draw nodes and arrows to represent activities and their relationships.
- Identify the Critical Path: Analyze the network to determine the longest path through the project.
Examples of Total Network Software:
- Microsoft Project: A widely used project management software with powerful features for creating and managing Total Networks.
- Primavera P6: A sophisticated project management software for complex projects, often used in large-scale construction and engineering projects.
- Smartsheet: A cloud-based project management tool with collaborative features for creating and managing project networks.
Conclusion:
A Total Network is an indispensable tool for successful project planning and scheduling. By visualizing the project's flow, identifying critical activities, and facilitating communication, it empowers project managers to make informed decisions and ensure project completion on time and within budget. Investing in understanding and utilizing Total Networks empowers teams to navigate the complexities of projects effectively and achieve desired outcomes.

Exercise: Constructing a Total Network
Scenario: You are planning a birthday party for your friend.
Instructions:
- Identify at least 5 activities required for the party.
- Sequence these activities in a logical order, considering dependencies between them.
- Assign an estimated duration (in hours) for each activity.
- Draw a simple Total Network diagram using nodes and arrows to represent the activities and their relationships.
- Identify the Critical Path in your network.
Hint: You can use a simple drawing tool or even a piece of paper to create your diagram.
Exercice Correction
Here's an example of a Total Network diagram for a birthday party:
Activities:
- A: Send Invitations (Duration: 2 hours)
- B: Buy Decorations (Duration: 3 hours)
- C: Prepare Food (Duration: 4 hours)
- D: Set Up Party Space (Duration: 2 hours)
- E: Bake Cake (Duration: 3 hours)
Network Diagram:
A ----> B ----> C ----> D ----> Party
| |
| |-----> E
Critical Path: A - B - C - D - Party
Note: This is just one possible solution. Your own network diagram may differ based on the activities you chose and the order you placed them in. The important thing is to understand the concept of a Total Network and how to apply it to a real-life scenario.
