What is Lean Six Sigma


In this article, you will learn what is Lean Six Sigma and how it differs from Lean Manufacturing.

What is Lean?

The fundamental driver of Lean is the elimination of waste. In fact, a good description of the Lean approach is, “a set of tools that assist in the identification and the steady elimination of waste.”

What is Six Sigma?

Six Sigma aims to improve the way the quality and measurement systems worked so as to eliminate errors in any area or kind of business, either services or products.

The Six Sigma approach is a general term focused on identifying and eliminating anything that caused variation in the process including but not limited to manufacturing.   Lean manufacturing is more focused and specialized to improve the manufacturing process and its related operations.

Six Sigma () is a set of techniques and tools for process improvement.

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 strategies seek to improve the quality of the output of a process by identifying and removing the causes of defects and minimizing impact variability in manufacturing and business processes.

It uses a set of quality management methods, mainly empiricalstatistical methods, and creates a special infrastructure of people within the organization who are experts in these methods.

Lean Six Sigma is a process improvement methodology designed to eliminate problems, remove waste and inefficiency, and improve working conditions to provide a better response to customers’ needs.

Typically, Lean Six Sigma is used in conjunction with Lean Manufacturing to reduce the variation and eliminate the eight kinds of waste (muda):

  1. Defects,
  2. Over-Production,
  3. Waiting,
  4. Non-Utilized Talent,
  5. Transportation,
  6. Inventory,
  7. Motion, and
  8. Extra-Processing.
