Which of the following best describes 5S on the Boeing production floor?

• A. 5S is a maintenance program focusing on equipment reliability.
• B. 5S means 'Score, Sort, Systemize, Simplify, Sustain'.
• C. 5S stands for Sort, Set in order, Shine, Standardize, Sustain and organizes the workplace to improve efficiency, quality, and safety.
• D. 5S is a statistical sampling method used on the shop floor.

Answer: (C)

FiveS is a Lean workplace organization method used on the Boeing production floor to create an orderly, efficient, and safe workspace. It consists of five steps: Sort removes unnecessary items from the area so only what is needed remains. Set in order arranges tools, materials, and equipment for easy access and smooth flow. Shine involves cleaning and inspecting the area to detect problems and maintain visibility. Standardize establishes consistent procedures and labeling so the practices are repeatable. Sustain keeps the discipline through audits and continual improvement to prevent slipping back into old habits. This approach organizes the work environment to minimize waste, reduce motion, improve quality by catching issues early during Shine, and enhance safety through clear layouts and visual controls. It is not a maintenance program focused on equipment reliability, nor a scoring or statistical sampling method, so those descriptions do not fit.
