Which scheduling method BEST shows the interrelationships of tasks?

The Critical Path Method (CPM) is a project scheduling technique that uses a network diagram to visually represent all project tasks and their logical dependencies. This method's primary strength is its ability to clearly illustrate the interrelationships between activities, showing which tasks must precede or follow others. By mapping these dependencies, CPM determines the longest sequence of tasks (the critical path), which dictates the minimum project completion time. Unlike other methods, the fundamental structure of a CPM diagram is built around showing these task relationships, making it the most effective tool for this specific purpose.

A. A work plan is a high-level document outlining project scope and deliverables; it does not graphically detail the interdependencies between individual tasks.

B. A Gantt chart is a bar chart that primarily visualizes the project timeline and task durations, but it is less effective at clearly showing complex task dependencies.

D. A milestone chart tracks major project events and deadlines but provides no information about the individual tasks or the relationships between them.

"Project Management

" the text explains that a limitation of the Gantt chart is that "it does not show the dependencies between tasks

" whereas the Critical Path Method (CPM) "graphically depicts all the tasks required... [and] the sequence in which they must occur." (pp. 9-6 to 9-7).

"Schedule Network Analysis

" the guide describes the Critical Path Method as a technique that uses a schedule model with a "logical network" of paths to analyze dependencies and determine schedule flexibility. The network diagram is the core component that shows these interrelationships.

noting that network diagrams (used in CPM and PERT) are specifically designed to "show the interrelationships and dependencies of one task on another." (p. 318).
