A project manager is planning a marketing campaign and needs to determine the optimal sequence for the various activities. She identifies that creating the campaign artwork must be completed before the social media posts can be scheduled, and the social media posts must be scheduled before the campaign can launch. What technique is she applying?
- AGantt Chart Development
- BResource Leveling
- CPrecedence Diagramming Method (PDM)
- DCritical Path Method
Show answer & explanationAnswer & explanation
Correct answer: C. Precedence Diagramming Method (PDM)
The Precedence Diagramming Method (PDM) is a technique used for building a project schedule network diagram that graphically represents the logical relationships (dependencies) among the project activities.
Why the other options are wrong
- A. Gantt Chart Development is a graphical representation of the project schedule, but not the technique for determining activity sequences.
- B. Resource Leveling is a technique to optimize resource allocation by addressing over-allocations or under-allocations.
- D. Critical Path Method (CPM) is a technique to determine the longest path through the project network diagram, which represents the shortest possible project duration.
Precedence Diagramming Method (PDM)
A technique used for building a project schedule network diagram that graphically represents the logical relationships (dependencies) among the project activities.
- Also known as Activity-on-Node (AON).
- Uses four types of logical relationships: Finish-to-Start (FS), Start-to-Start (SS), Finish-to-Finish (FF), Start-to-Finish (SF).
- Forms the basis for schedule analysis.
