Exercise: Building a Simple Scheduled Network

Scenario: You are organizing a company picnic. Create a simple scheduled network for the event, including the following activities:

• Activity 1: Send out invitations
• Activity 2: Reserve the park location
• Activity 3: Order food and drinks
• Activity 4: Organize games and activities
• Activity 5: Set up the picnic area
• Activity 6: Clean up after the event

Instructions:

1. Identify dependencies: Which activities need to be completed before others can begin?
2. Estimate time durations: Assign a realistic time estimate (in days) to each activity.
3. Create a network diagram: Use a simple flowchart or any other suitable visual representation to connect the activities and show their dependencies.

Example:

• Activity 1 (Send out invitations) needs to be completed before Activity 2 (Reserve the park location) can begin.

                  ↑
        ┌────────────┐
        │ Activity 3 │
        └────────────┘
                  ↓
        ┌────────────┐
        │ Activity 4 │
        └────────────┘

Navigating the Network: Understanding Scheduled Networks in Project Planning & Scheduling

This document expands on the provided introduction to scheduled networks, breaking the topic down into distinct chapters.

Chapter 1: Techniques for Creating Scheduled Networks

Creating a scheduled network involves several key techniques, focusing on defining activities, dependencies, and durations. The accuracy and effectiveness of the network directly depend on the precision of these techniques.

Activity Definition and Decomposition: The first step is a thorough Work Breakdown Structure (WBS) to break the project into smaller, manageable tasks (activities). Each activity should be clearly defined, with specific, measurable, achievable, relevant, and time-bound (SMART) objectives. Vague activities lead to inaccurate scheduling.

Dependency Identification: This crucial step defines the relationships between activities. Several dependency types exist:

• Finish-to-Start (FS): Activity B cannot start until Activity A finishes. This is the most common type.
• Start-to-Start (SS): Activity B cannot start until Activity A starts. Useful for parallel activities requiring simultaneous initiation.
• Finish-to-Finish (FF): Activity B cannot finish until Activity A finishes. Often used for handover processes.
• Start-to-Finish (SF): Activity B cannot finish until Activity A starts. Less common, but applicable in certain scenarios.

Clearly defining these dependencies is critical for accurate scheduling. Lag time (delay between activities) can also be incorporated into these relationships.

Time Estimation Techniques: Accurately estimating activity durations is vital. Several techniques exist:

• Three-Point Estimation: This involves estimating an optimistic (O), most likely (M), and pessimistic (P) duration for each activity. The weighted average ((O + 4M + P) / 6) provides a more robust estimate than a single-point estimate.
• Expert Judgment: Leveraging the experience and knowledge of project team members to estimate durations.
• Analogous Estimating: Using durations from similar past projects as a baseline.
• Parametric Estimating: Using statistical relationships between project parameters (e.g., size, complexity) and duration.

Chapter 2: Models for Representing Scheduled Networks

Two primary models visually represent scheduled networks:

Arrow Diagramming Method (ADM): This method represents activities as arrows and events (milestones) as nodes. Dependencies are shown by the arrow's flow. ADM is useful for visually identifying the critical path but can become complex for large projects.

Precedence Diagramming Method (PDM): This method uses nodes to represent activities and arrows to show dependencies. It's more flexible than ADM, allowing for more complex dependencies and easier representation of large projects. PDM is generally preferred for its clarity and ease of use in modern project management software.

Both methods facilitate critical path analysis, identifying the sequence of activities that determines the shortest possible project duration. Any delay on the critical path directly impacts the overall project completion date.

Chapter 3: Software for Scheduled Network Management

Numerous software applications facilitate creating, managing, and analyzing scheduled networks:

• Microsoft Project: A widely used tool offering features for task management, resource allocation, critical path analysis, and Gantt chart generation.
• Primavera P6: A powerful, enterprise-level project management software ideal for large, complex projects. It includes advanced features like resource leveling, risk management, and multi-project scheduling.
• OpenProject: An open-source project management software providing many of the features found in commercial options.
• Asana, Trello, Monday.com: While not dedicated project management software, these tools offer basic scheduling and task management functionalities.

Software selection depends on project size, complexity, and budget. Features to consider include Gantt chart visualization, critical path analysis, resource allocation capabilities, and integration with other project management tools.

Chapter 4: Best Practices for Scheduled Network Management

Effective scheduled network management requires adherence to best practices:

• Regular Updates: The network should be regularly updated to reflect actual progress and any changes to the project scope or schedule.
• Collaboration: Involve the entire project team in the creation and maintenance of the network to ensure accuracy and buy-in.
• Baseline Creation: Establish a baseline schedule against which actual progress can be compared.
• Risk Management: Identify and assess potential risks that could impact the schedule. Develop mitigation plans to address these risks.
• Change Management: Establish a formal process for managing changes to the schedule.
• Communication: Regularly communicate the project schedule and any changes to stakeholders.
• Continuous Improvement: Regularly review the effectiveness of the scheduling process and make improvements as needed.

Chapter 5: Case Studies of Scheduled Network Applications

Illustrative examples showcasing the application of scheduled networks across diverse projects:

(Case Study 1: Construction Project): A large-scale building project utilizes Primavera P6 to manage the intricate network of activities, including foundation work, structural framing, MEP installations, and finishing. The software facilitates resource allocation, critical path analysis, and progress tracking, enabling efficient project completion.

(Case Study 2: Software Development Project): A software development team uses Microsoft Project to manage sprints, dependencies between development tasks, testing phases, and deployment. The scheduled network helps visualize task dependencies and track progress against sprint goals.

(Case Study 3: Event Planning): An event organizer employs a simple project management tool to schedule tasks such as venue booking, vendor coordination, marketing campaigns, and logistics. The visual representation clarifies task dependencies and potential scheduling conflicts.

These case studies highlight how scheduled networks enhance project planning and execution across diverse industries and project types, regardless of complexity. The adaptability and scalability of the approach make it a valuable tool for any project manager.
