Strength and power are gained through this precise and detailed approach of gathering and analyzing data. Emphasis is placed on the idea that process speed is directly tied to excellence. Even the most minor opportunities for process improvement are detected and acted upon, enabling organizations to reach their highest levels of performance. Originally developed as a set of practices designed to improve manufacturing with lean tools, it now extends into other types of business processes as well. This lean solution accentuates several beliefs including:
Lean manufacturing is a process improvement methodology based upon the highly acclaimed Toyota Production System (TPS). The main focus in lean manufacturing is the removal of waste from a value stream. Waste in this instance is defined as anything that consumes resource but does not add value for the customer. By removing the waste in a value stream it becomes possible to only produce the right material, in the quantity desired by the customer, at exactly the right time. This results in a process that is more efficient and delivers product to the customer more quickly. The elements within a value stream that add value for the customer tend to represent a very small percentage of the total process. Therefore focusing on removing the waste , or non-value adding elements represents a significant opportunity for improvement in many businesses.
Frederick Winslow Taylor , the father of scientific management , introduced what are now called standardization and best practice deployment. In Principles of Scientific Management , (1911), Taylor said: "And whenever a workman proposes an improvement, it should be the policy of the management to make a careful analysis of the new method, and if necessary conduct a series of experiments to determine accurately the relative merit of the new suggestion and of the old standard. And whenever the new method is found to be markedly superior to the old, it should be adopted as the standard for the whole establishment."
