The 5 S of Lean Process
There are five 5S phases: They can be translated from the Japanese as "sort", "straighten", "shine", "standardise", and "sustain". Other translations are possible.

Other phases are sometimes included e.g. safety, security, and satisfaction. These however do not form a traditional set of "phases" as the additions of these extra steps are simply to clarify the benefits of 5S and not a different or more inclusive methodology.
The phase "Safety" is sometimes added. There is debate over whether including this sixth "S" promotes safety by stating this value explicitly, or if a comprehensive safety program is undermined when it is relegated to a single item in an efficiency-focused business methodology.
The phase "Security" can also be added. To leverage security as an investment rather than an expense, the seventh "S" identifies and addresses risks to key business categories including fixed assets (PP&E), material, human capital, brand equity, intellectual property, information technology, assets-in-transit and the extended supply chain. Techniques are adapted from those detailed in Total security management (TSM) or the business practice of developing and implementing comprehensive risk management and security practices for a firm’s entire value chain.
