Lean manufacturing is a method of manufacturing goods aimed primarily at reducing times within the production system as well as response times from suppliers and customers. It is closely related to another concept called just-in-time manufacturing (JIT manufacturing in short).
It was developed as a guide for managers of manufacturing plants on how to combine lean manufacturing and Six Sigma to improve quality and cycle time in the plant. [5] In the early 2000s Six Sigma principles expanded into other sectors of the economy, such as healthcare, finance, and supply chains. [citation needed]
Six Sigma (6σ) is a set of techniques and tools for process improvement.It was introduced by American engineer Bill Smith while working at Motorola in 1986. [1] [2]Six Sigma strategies seek to improve manufacturing quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes.
The classic TPM process he developed consisting of 5 principles was later enhanced by the JIPM to incorporate many of the lessons of lean manufacturing and is referred to as Company-Wide TPM which consists of 8 principles/activities. The name "Pillar" is symbolically used as a structural support to the structure of TPM.
The Toyota Way is a set of principles defining the organizational culture of Toyota Motor Corporation. [1] [2] The company formalized the Toyota Way in 2001, after decades of academic research into the Toyota Production System and its implications for lean manufacturing as a methodology that other organizations could adopt.

Design for lean manufacturing is a process for applying lean concepts to the design phase of a system, such as a complex product or process. The term describes methods of design in lean manufacturing companies as part of the study of Japanese industry by the Massachusetts Institute of Technology.
The application of Lean in product development and manufacturing are different. Some aspects may look similar, but they are not! Be wary of an expert with experience in lean manufacturing who claims to know product development." [7] The most common high-level concepts associated with lean product development are: Creation of re-usable knowledge ...
As in the manufacturing and service sectors, some government agencies are implementing Lean methods in conjunction with Six Sigma process improvement approaches. [ 8 ] A source that lists all current vetted Lean Government initiatives at the Federal, State, City, County, and K-12 school levels is the Lean Government Center (since 2008): http ...
