Six Sigma Green Belt Certification Practice Exam

The method used to clean the work environment as part of waste elimination is 5S. This methodology focuses on organizing and managing the workspace and work flow with the goal of improving efficiency, reducing waste, and ensuring safety. The five steps of 5S—Sort, Set in order, Shine, Standardize, and Sustain—guide teams in maintaining a clean and orderly environment. By emphasizing cleanliness and organization, 5S helps to eliminate waste associated with searching for tools, materials, or information, leading to more streamlined processes and improved productivity.

While other choices serve important functions in quality improvement and waste reduction, they address different aspects. For instance, Kaizen focuses on continuous improvement in processes, Poka-yoke is aimed at error-proofing processes, and SMED (Single-Minute Exchange of Die) is specifically about reducing setup times. None of these methods center on cleaning and organizing the workspace to the extent that 5S does.
