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.
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.
Design for Six Sigma emerged from the Six Sigma and the Define-Measure-Analyze-Improve-Control (DMAIC) quality methodologies, which were originally developed by Motorola to systematically improve processes by eliminating defects. Unlike its traditional Six Sigma/DMAIC predecessors, which are usually focused on solving existing manufacturing ...
Zero Defect Program — created by NEC Corporation of Japan, based upon statistical process control and one of the inputs for the inventors of Six Sigma. Six Sigma — 6σ, Six Sigma combines established methods such as statistical process control, design of experiments and failure mode and effects analysis (FMEA) in an overall framework.

Lean enterprise is a practice focused on value creation for the end customer with minimal waste and processes. [4] The term has historically been associated with lean manufacturing and Six Sigma (or Lean Six Sigma) due to lean principles being popularized by Toyota in the automobile manufacturing industry and subsequently the electronics and internet software industries.
Zero Defects (or ZD) was a management-led program to eliminate defects in industrial production that enjoyed brief popularity in American industry from 1964 [1] to the early 1970s. Quality expert Philip Crosby later incorporated it into his "Absolutes of Quality Management" and it enjoyed a renaissance in the American automobile industry—as a ...
It is intended to enable employees to identify, deliver, and enhance the flow of value to customers. Common frameworks associated with operational excellence include: lean management and Six Sigma, which emphasize efficiency, waste reduction, and quality improvement. Organizations that adopt these practices may report increased customer ...
