    Topics Covered - Week 3: Project Network Diagram (Discrete Approach)

    • What is a Project Network Diagram?
    • Different approaches to the Project Network Diagram
      • Precedence Diagramming Method
      • Other Approaches
    • Project Duration, Critical Path and Near-Critical Path
    • Limitation of Discrete Approach to Project Network Diagram

    Network Diagram

    • Building Gate and Fence Project:
      • First task: Dig Holes
      • Buy Wood and Buy Gate can start after Dig Holes. -Erect Fence requires Buy Wood -Buy Paint requires Buy Gate -Erect Gate requires Erect Fence and Buy Paint -Paint Fence requires Erect Gate -Paint Gate requires Paint Fence -Network diagrams are visual representations of a project's schedule. -Illustrates logical events leading to project completion. -Used to plan and track projects from start to finish. -Represent critical path and project scope. -Used for ease of readability to show activity sequence, and parallel activities, and connections between activities.
    • Rules of Thumb for Network Diagrams:
      • Starting point
      • Ending point -Predecessors for all activities (except the start point) -Successors for all activities (except the endpoint) -No loops or hangers

    Precedence Diagramming Method (PDM)

    • Node represents activity
    • Also known as activity-on-node (AON) diagrams

    Other Approaches for Network Diagram

    • Arrow Diagramming Method
    • Critical Chain Approach
    • Line of Balance Approach
    • Advanced Work Package Approach
    • Beeline Diagramming Method
    • Chronographic Modeling Approach
    • Timeboxing
    • Kanban

    Critical Path

    • Critical Path: The sequence of activities that determine the duration of the project. It's the longest path through the project.
    • Forward Pass: Identifies early start (ES) and early finish (EF) dates.
    • Backward Pass: Identifies the late start (LS) and late finish (LF) dates. -Use formulas (ES + duration = EF) and (EF + lag = ES, EF – lead = ES) for successors.
    • Important for project managers to calculate slack times -Tasks on the critical path have a slack of 0

    Slack Time (Float Time)

    • Amount of time a task can be delayed without delaying project completion or subsequent task start.
    • Total Slack = Late Finish – Early Finish or Total Slack = Late Start – Early Start

    Near-Critical Path

    • One or more paths in the project that are not initially critical but may become critical due to events like longer durations or improved performance of non-critical tasks. -Probabilistic outcome of task/task duration plays a major variable.

    Review Questions

    • Differences between critical and near-critical paths
    • Network diagrams with zero critical paths or zero near-critical paths
    • Calculation of task slack time, and its importance for project managers.
    • Tasks with zero slack
    • Loops in a network diagram
    • Rules of thumb for drawing network diagrams
