5S + 1
• Introduction
• Background and History
• Components and Implementation
2
• 5S + 1 is a method to improve and sustain workplace organization
• Represents 6 disciplines for maintaining a visual workplace
(visual controls and information systems).
• These are foundational to continual improvement and a manufacturing strategy based on "Lean Manufacturing"
(waste removing) concepts.
• Reduces clutter
• Reduces the time it takes to look for tools and equipment
• “A place for everything and everything in its place”
• Improves how the operation appears to customers – always be “tour ready”
• Creates pride in the workplace
• Many companies have a standard that any tool must be able to be found within 60 seconds.

• Taiichi Ohno created the original “4S” concept of workplace organization and visual control at Toyota during the early 1950’s.
• The concept was further refined into “5S” during the 1960’s and 1970’s.
• U.S. manufacturers added a sixth “S” for “safety” during the 1990’s.
• The 5S+1 tools were recently modified by
Gwendolyn Galsworth to include “Visual
Workplace” disciplines.
