| Summary: | "Lean is one type of organizational change and improvement methods by cost reduction mechanism. The assumption is, by reducing costs, the organizations can work better and more efficiently. All changes in lean-based organizations are directed at reducing these costs by identifying and eliminating waste. The thinking is that cost reduction will increase efficiency since basically, cost reduction occurs due to the loss of process inefficiencies and decreases of cycle time. Why are targets directed at cost reduction? Because costs are a crucial factor for sustainable business organization. Lean thinking cuts the value of scale production by looking at the existing waste in a process. Production remains the same, but the costs of goods production is reduced due to the elimination of waste in the process. As a result, companies do not have to increase their production if it is not required, giving companies an increase in average profits due to lean and the elimination of identified waste. This becomes the second part of the fourth definition which focuses on cost reduction. the focus on cost reduction can be included in the overall lean concept since cost wasting is only a part of the existing waste. Actually, other wastes can be converted into costs or in other words, perceived by the money value. This book starts the mental process of organization change through Lean thinking. It provides the background and history of lean and moves to how the lean process works. The author also discusses why an organization should implement lean as a method to increase quality and engage workers in the process thereby increasing efficiency and ultimately profitability. Through case studies and examples from Indonesia, the author describes how to create a value stream to identify waste and discusses the concept of a pull system and its impact on the process"--
