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] Jack Welch made it central to his business strategy at General Electric in 1995. A six sigma process is one in which 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects.

Six Sigma is a quality-control methodology developed in 1986 by Motorola, Inc. The method uses a data-driven review to limit mistakes or defects in and process. Six Sigma emphasizes cycle-time improvement while at the same time reducing manufacturing defects to a level of no more than 3.4 occurrences per million units or events. In other words, the system is a method to work faster with fewer mistakes.
Six Sigma is a method that provides organizations tools to improve the capability of their business processes. This increase in performance and decrease in process variation helps lead to defect reduction and improvement in profits, employee morale, and quality of products or services.
Globalization and instant access to information, products and services have changed the way our customers conduct business — old business models no longer work. Today’s competitive environment leaves no room for error. We must delight our customers and relentlessly look for new ways to exceed their expectations. This is why Six Sigma Quality has become a part of our culture

If you’ve heard some buzz about Lean tools and principles, you’re not alone. Lean tools got their start in America as early as the 1900s, when Henry Ford used Lean methodology to create the Model T assembly line. Lean methodology also has an expansive legacy outside the U.S., with companies such as Toyota making considerable breakthroughs in the application of Lean Tools throughout the 1930s.
In addition to being the first to correctly implement the Lean tool Just-In-Time, for example, Toyota is also known for creating its own Lean Production System. In this article, we’ll explore what Lean tools are and discuss the applications for seven common ones that you’ll encounter in Lean Six Sigma.

Lean Six Sigma is a continuous improvement methodology that focuses on the elimination of waste and reduction of variation from manufacturing, service and design processes. The Lean methodology aims at reducing non-value activities and cycle times while creating value for customers. Six Sigma identifies and reduces variability, improving overall quality. LSS can reduce your costs and help you retain and even gain more customers.
LSS prescribes an improvement process known as DMAIC (Define—Measure—Analyze—Improve—Control). However, its application is limited to improving existing processes. It doesn’t address the design of new products, services, or processes.
For developing a new product, service or process, there’s a modified version called DFSS (Design for Six Sigma). The process most often used in DFSS is called DMADV (Define—Measure—Analyze—Design—Verify)
