One of the key steps in lean process and TPS is to identify which activities add value and which do not, then to progressively work to improve or eliminate them. Taiichi Ohno, "father" of the Toyota Production System, originally identified seven forms of muda or waste: [6] Seven types of waste identified in lean manufacturing
Ohno Taiichi (大野耐一, Ōno Taiichi, February 29, 1912 – May 28, 1990) was a Japanese industrial engineer and businessman. He is considered to be the father of the Toyota Production System, which inspired Lean Manufacturing in the U.S. [1] [2] He devised the seven wastes (or muda in Japanese) as part of this system.
The seven "wastes" (muda in Japanese), first formulated by Toyota engineer Shigeo Shingo, are the waste of superfluous inventory of raw material and finished goods, the waste of overproduction (producing more than what is needed now), the waste of over-processing (processing or making parts beyond the standard expected by customer), the waste ...
The seven types of waste (seven Muda) as typical sources of loss. The waste itself is the obvious cause of losses. A distinction is made between seven types of waste that occur almost everywhere in the company. Muda due to overproduction Produce more than necessary. Muda due to waiting time Inactive hands of an employee.
Design for lean manufacturing was first coined by Womack, Jones, and Roos after studying the differences between conventional development at American automotive companies and lean methods at Japanese automobile producers. [7] While lean manufacturing focuses on optimization of the production stream and removal of wastes (commonly referred to as ...

Lean Six Sigma is a synergized managerial concept of Lean and Six Sigma. [6] Lean traditionally focuses on eliminating the eight kinds of waste ("muda"), and Six Sigma focuses on improving process output quality by identifying and removing the causes of defects (errors) and minimizing variability in (manufacturing and business) processes.
