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) emphasizes maintaining and improving quality standards across processes rather than specifically targeting bottlenecks. While beneficial for overall quality control, a QMS does not provide a focused approach for identifying and resolving the most significant constraints in a support process.

Six Sigma aims to reduce defects and improve process quality through statistical methods. Although it can be beneficial for process improvement, it is broader in scope and not solely focused on identifying and managing bottlenecks like the theory of constraints. It could lead to quality improvements but may not directly address the time-consuming step in the customer-care process.

A Kanban system is a visual workflow management method that helps manage tasks and optimize flow. While it improves efficiency by visualizing work in progress, it does not specifically target bottlenecks in the same way the theory of constraints does, making it less effective for resolving the highlighted issue within the support process.
