Which project management technique is used to determine the longest sequence of dependent tasks?

• A. Gantt Chart
• B. Holistic Management
• C. Critical Path Method (CPM)
• D. Time-Value Analysis

Answer: (C)

The Critical Path Method (CPM) is a project management technique specifically designed for scheduling project tasks by identifying the longest sequence of dependent tasks, known as the critical path. This method helps project managers determine which tasks directly impact the project duration. By focusing on these critical tasks, the project manager can prioritize resources and manage timelines effectively.

Understanding the critical path is essential because it allows for the identification of tasks that cannot be delayed without affecting the overall project completion date. Inherent within this method is the calculation of the earliest start and finish times for each task, as well as the latest start and finish times, which are key to determining float or slack time for non-critical tasks. This analysis ensures that project managers can make informed decisions regarding resource allocation, scheduling adjustments, and potential delays.

Other options present methodologies or tools that do not focus on identifying the critical tasks that influence the project timeline directly. For example, a Gantt Chart is a visual representation of a project schedule and while it shows task durations and overlaps, it does not inherently analyze dependencies or determine the critical path itself. Holistic Management refers to a broader approach to management that may not specifically address task scheduling, and Time-Value Analysis relates to the financial aspect of cash flows over time, rather
