- 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.
