A project manager is overseeing the development of a new mobile application. During the planning phase, the team needs to determine the optimal sequence of project activities and their dependencies to achieve the project objectives efficiently. Which of the following tools or techniques would be most appropriate for this task?
- AVariance analysis
- BPrecedence Diagramming Method (PDM)
- CResource leveling
- DEarned Value Management (EVM)
Show answer & explanationAnswer & explanation
Correct answer: B. Precedence Diagramming Method (PDM)
The Precedence Diagramming Method (PDM) is a scheduling technique used to graphically represent activity dependencies. It helps in determining the logical sequence of activities, which is crucial for efficient project planning.
Why the other options are wrong
- A. Variance analysis is used for performance measurement, not for sequencing activities.
- C. Resource leveling is used to adjust schedules due to resource constraints, not to determine the initial activity sequence.
- D. EVM is a performance measurement technique, not a tool for activity sequencing.
Precedence Diagramming Method (PDM)
A technique used for constructing a schedule model where activities are represented by nodes and are graphically linked by one or more logical relationships to show the sequence in which the activities are to be performed.
- Uses nodes for activities and arrows for dependencies.
- Helps visualize the project schedule flow.
- Identifies logical relationships between activities.
Memory trick: Precedence Diagrams Clearly Map Dependencies.
