Which of the following is not part of the 5S method?

• A. Streamline It
• B. Sort
• C. Set in order
• D. Sustain

Answer: (A)

This question tests your knowledge of the 5S method used to organize and maintain a clean, efficient workspace. The five S’s are Sort, Set in order, Shine, Standardize, Sustain. Among the options, the one that does not fit is the term that reads “Streamline It.” That phrase isn’t one of the five steps; it’s a general idea about making processes smoother, which sits outside the specific 5S framework. The other terms map directly to the actual steps: Sort removes unnecessary items, Set in order arranges items for easy access, Sustain focuses on maintaining the improvements over time (with standards and ongoing discipline), while Shine and Standardize complete the remaining S’s by cleaning and establishing procedures.
