In 5S, what are the five S's and their purpose?

• A. Sort, Set in order, Shine, Standardize, Sustain; to organize workspace for efficiency and quality.
• B. Sort, Set in order, Shine, Standardize, Sustain; to reduce waste.
• C. Sharpen, Sort, Sweep, Standardize, Sustain; to organize workspace.
• D. Sort, Set in order, Shine, Standardize, Sustain; to promote safety training.

Answer: (A)

The practice of 5S is a structured approach to organizing the workplace using five steps: Sort, Set in order, Shine, Standardize, Sustain. The purpose is to organize the workspace to improve efficiency and quality. Sorting means removing items that aren’t needed so space and flow aren’t cluttered. Setting in order ensures tools and materials are arranged for easy access and use, reducing wasted movement. Shining involves cleaning and inspecting regularly, which helps reveal problems and keeps the area safe and reliable. Standardizing creates consistent methods, labeling, and routines so everyone follows the same process. Sustaining makes these practices habitual, with ongoing checks to keep gains over time.

This framing highlights the broad goal: a well-organized, clean, and standardized workplace that supports efficient performance and quality. The other descriptions either narrow the aim to just reducing waste, use an incorrect term (for example, using Sharpen instead of Shine), or emphasize safety training, which isn’t the primary stated purpose of 5S.
