The 5-S philosophy is associated with lean thinking. The objective of lean thinking is to provide a business with long-term profitability by developing a more effective workplace, which is accomplished by eliminating waste in the work environment. The result is a safer workplace, improved product quality, and lower costs for both the business and its customers.
Lean thinking may result in a reduction in work force, but that is not its purpose. In fact, the application of lean thinking for the purpose of reducing the work force is not lean thinking at all. Since some companies have done this, lean thinking has been given a bad reputation and has made waste reduction efforts more difficult.
