What scheduling technique involves identifying activities and their relationships presented in a graphical network?

The scheduling technique that involves identifying activities and their relationships through a graphical network is commonly associated with the Critical Path Method (CPM). CPM utilizes a network diagram to visually represent the project's tasks, their durations, and the dependencies between these tasks. This approach allows project managers to determine the longest path of planned activities necessary to complete a project, helping to identify which tasks are critical for timely project completion and which can be delayed without affecting overall project duration.

While PERT (Program Evaluation Review Technique) also uses a network diagram to analyze project tasks and timelines, it primarily focuses on estimating project timeframes and uncertainties associated with time estimates, which differentiates it from CPM. Gantt charts, on the other hand, provide a visual representation of a project schedule but do not typically illustrate the relationships and dependencies between tasks as a network does. SWOT analysis is a strategic planning tool for assessing strengths, weaknesses, opportunities, and threats and is unrelated to scheduling techniques. Hence, CPM is the most relevant choice for the question posed.
