CompTIA Project+ (PK0-005)Project Life Cycle PhasesMedium
A project manager is leading a large, complex IT infrastructure upgrade. Multiple teams are involved, and their activities have numerous interdependencies. To effectively visualize the sequence of work and identify potential bottlenecks, the project manager creates a graphical representation showing the logical relationships between project activities. What is this representation called?
- ANetwork Diagram
- BGantt Chart
- CWork Breakdown Structure (WBS)
- DResource Histogram
Show answer & explanationAnswer & explanation
Correct answer: A. Network Diagram
A network diagram is a visual representation of the sequence of activities and their logical relationships in a project schedule.
Why the other options are wrong
- B. A Gantt Chart is a bar chart showing the start and finish dates of project activities, but it doesn't explicitly show logical relationships as clearly as a network diagram.
- C. A Work Breakdown Structure (WBS) is a hierarchical decomposition of the total scope of work, not a representation of activity sequences.
- D. A Resource Histogram is a bar chart showing the number of resources required over time, not the sequence of activities.
Network Diagram
A graphical representation of the logical relationships among the project schedule activities.
- Shows activity sequence and dependencies.
- Used to calculate the critical path.
- Helps identify potential bottlenecks and float.
Memory trick: Network diagrams map activity flows.
