Which principle is NOT included in the five ‘S’ methodology?

The five ‘S’ methodology, which is a system for organizing spaces so work can be performed efficiently, includes Sort, Set in order, Shine, Standardize, and Sustain. Each of these components is essential to creating an organized and high-functioning work environment.

The principle of 'Simplify' is not part of the five ‘S’ framework. Instead, 'Sort' refers to the process of distinguishing between necessary and unnecessary items, allowing a workspace to be decluttered. The focus of 'Set in order' is on arranging tools and materials in a way that enhances workflow. 'Shine' emphasizes cleanliness and maintaining a tidy work area. 'Standardize' involves creating consistent practices for maintaining the first three S's, and 'Sustain' encourages maintaining discipline to ensure that the organization becomes habitual.

Therefore, 'Simplify' does not fit with the established principles of the five ‘S’ methodology, which emphasizes structuring and organizing workspace rather than simply simplifying processes.
