An analyst is eliminating bottlenecks from the customer-care support process of an airline. One step in the process is consuming much more time than the other steps. Which methodology can be used to maximize the results?

A Quality Management System (QMS) involves the overall management of quality across processes but does not specifically target bottlenecks. While it can improve quality and efficiency, it lacks the focused approach on constraints that TOC provides, making it less effective for resolving specific time-consuming steps.

Six Sigma is a data-driven methodology aimed at reducing defects and variability in processes. Although it can help optimize processes, its primary focus is on quality improvement rather than specifically addressing bottlenecks. Therefore, it may not directly maximize results in the same way that TOC does by isolating and improving the most constraining step.

The Kanban system is a visual workflow management tool that helps manage and improve work processes by visualizing tasks and limiting work in progress. While it supports efficiency, it does not specifically focus on identifying and eliminating bottlenecks, which is the core principle of TOC.
