APPLICATION OF TOOLS AND TECHNIQUES FOR DETERMINING THE DURATION OF TASKS AND BUFFERS IN THE CRITICAL CHAIN METHOD

The Critical Chain Method (CCM) is a method widely used in Project Management to take into account the resource constraints and uncertainty that may arise when developing a project schedule.For this purpose, this method uses buffers, which absorb the delays that project activities could suffer during execution.This article proposes a methodology for determining the duration of tasks and buffers of a project by combining several tools and techniques commonly used in project management, including expert judgment, three-valued duration estimation (analyzing the best alternative based on the maturity of the project), Delphi methodology for collecting the opinions of the expert panel on the duration of tasks, and Monte Carlo simulation to optimize the durations of tasks and buffers of the project.
