5S refers to five related terms, beginning with an S sound, describing workplace practices conducive to visual control and lean production. The five terms in Japanese are:<\/p>\n

    \n
  1. Seiri:<\/strong> Separate needed from unneeded items\u2014tools, parts materials, paperwork\u2014and discard the unneeded.<\/li>\n
  2. Seiton:<\/strong> Neatly arrange what is left\u2014a place for everything and everything in its place.<\/li>\n
  3. Seiso:<\/strong> Clean and wash.<\/li>\n
  4. Seiketsu:<\/strong> Cleanliness resulting from regular performance of the first three Ss.<\/li>\n
  5. Shitsuke:<\/strong> Discipline, to perform the first four Ss.<\/li>\n<\/ol>\n

    The Five Ss often are translated into English as Sort, Straighten, Shine, Standardize, and Sustain. Some lean practitioners add a sixth S for Safety: Establish and practice safety procedures in the workshop and office.<\/p>\n

    However, Toyota traditionally refers to just Four Ss:<\/p>\n

      \n
    1. Sifting (Seiri):<\/strong> Go through everything in the work area, separating and eliminating what isn\u2019t needed.<\/li>\n
    2. Sorting (Seiton):<\/strong> Arrange items that are needed in a neat and easy-to-use manner.<\/li>\n
    3. Sweeping Clean (Seiso):<\/strong> Clean up the work area, equipment, and tools.<\/li>\n
    4. Spic and Span (Seiketsu):<\/strong> The overall cleanliness and order that result from disciplined practice of the first three Ss.<\/li>\n<\/ol>\n

      The last S\u2014shitsuke (sustain)\u2014is dropped because it becomes redundant under Toyota\u2019s system of daily, weekly, and monthly audits to check standardized work. Whether four, five, or six Ss are used, the key point to remember is that the effort is systematic and organic to lean production, not a “bolt-on” stand-alone program.<\/p>\n\n\n

      What Is the Purpose of 5S?<\/h2>\n\n\n\n

      The true purpose of 5S goes deeper than a one-time housecleaning. The 5S methodology is a way to: create standards that reveal problems, support the basic stability needed to sustain incremental gains, reduce waste<\/a> in all forms, build a disciplined workplace where teams focus on value<\/a>-creating work, and nurture the essential sense of shared purpose needed to continuous improve to take root. An elegant way of describing this can be found in Gwendolyn Galsworth\u2019s Visual Workplace, Visual Thinking<\/em><\/a>: \u201cThe 5S system is designed to create a visual workplace, that is, a work environment that is self-explaining, self-ordering, and self-improving.\u201d<\/p>\n\n\n\n

      Beware: Many stress the hazards of misguided 5S \u201cprograms\u201d that merely add bureaucratic rules that prevent new learning and disable true initiative. \u201c5S really is a method to teach people to take ownership of their own work environment so that they can perfect their standardized work<\/a> by placing things at their most convenient place. Instead, in most companies I visit, 5S has become a bureaucratic program to make the workplace look neat, with no consideration for waste all over, and a fixation on \u201cdiscipline.\u2019\u201d Ball\u00e9 adds in How Can I Keep Our Lean Management Effort From Becoming Bureaucratic<\/a>.<\/p>\n\n\n\n
