( July 2014 ) Lean Six Sigma is a methodology that relies on a collaborative team effort to improve performance by systematically removing waste and reducing variation. It combines lean manufacturing / lean enterprise and Six Sigma to eliminate the eight kinds of waste ( muda ) : Defects Over-Production Waiting Non-Utilized Talent Transportation Inventory Motion Extra-Processing Lean six sigma not only reduces process defects and waste, but also provides a framework for overall organizational culture change.

'' As mentioned above, there are eight different types of waste. Each one is defined below : Over production is excess amount of product that is produced. Idle time waste, or wait time waste, is down time that is spent waiting for a product to be created. The delivery waste, or transportation waste, is the time spent getting the product shipped to the recipient. Waste in the work, inventory, and operations is time spent loosely and does not make money. Waste in the work is also known as extra-processing waste, and waste in operations is also known as motion waste. Rejected parts waste, or defects waste, is when certain pieces should be thrown out or reworked because they are not within tolerance. Lastly, we have non-utilized talent waste which is when a person that is untrained for a position is put there to try and complete work. History 1980s - 2000s What was today to become Lean Six Sigma can be traced to Motorola in the United States in 1986 to compete with the Kaizen business model in Japan. In the 1990s Allied Signal hired Larry Bossidy and introduced Six Sigma in heavy manufacturing. General Electric 's Jack Welch consulted Bossidy and began Six Sigma at General Electric. During the 2000s Lean Six Sigma forked from Six Sigma. 2000s - 2010s The first concept of Lean Six Sigma was created in 2001 by a book titled Leaning into Six Sigma : The Path to integration of Lean Enterprise and Six Sigma by Barbara Wheat, Chuck Mills, Mike Carnell. In the early 2000s Six Sigma principles expanded into other sectors of the economy, such as Healthcare, Finance, Supply Chain, etc. Description Lean Six Sigma is a synergized managerial concept of Lean and Six Sigma. Lean traditionally focuses on the elimination of the eight kinds of waste / muda classified as defects, over-production, waiting, non-utilized talent, transportation, inventory, motion and extra-processing. Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects ( errors ) and minimizing variability in ( manufacturing and business ) processes. Synergistically, Lean aims to achieve continuous flow by tightening the linkages between process steps while Six Sigma focuses on reducing process variation ( in all its forms ) for the process steps thereby enabling a tightening of those linkages. In short, Lean exposes sources of process variation and Six Sigma aims to reduce that variation enabling a virtuous cycle of iterative improvements towards the goal of continuous flow. Lean Six Sigma uses the DMAIC phases similar to that of Six Sigma. Lean Six Sigma projects comprise aspects of Lean 's waste elimination and the Six Sigma focus on reducing defects, based on critical to quality characteristics. The DMAIC toolkit of Lean Six Sigma comprises all the Lean and Six Sigma tools. The training for Lean Six Sigma is provided through the belt based training system similar to that of Six Sigma. The belt personnel are designated as white belts, yellow belts, green belts, black belts and master black belts, similar to judo. Lean Six Sigma organization structure For each of these belt levels skill sets are available that describe which of the overall Lean Six Sigma tools are expected to be part at a certain Belt level. These skill sets provide a detailed description of the learning elements that a participant will have acquired after completing a training program. The level upon which these learning elements may be applied is also described. The skill sets reflect elements from Six Sigma, Lean and other process improvement methods like the theory of constraints ( TOC ) total productive maintenance ( TPM ). How Lean and Six Sigma come together Lean six sigma organizes lean and six sigma to cut production costs, improve quality, speed up, stay competitive, and save money. From six sigma they gain the reduced variation on parts. Also, lean focuses on saving money for the company by focusing on the types of waste and how to reduce the waste. The two coming into lean six sigma to better each other creating a well balanced and organized solution to save money and produce better parts consistently. Tools for Lean and Six Sigma Lean : Kaizen, Value Stream Process Mapping, 5s, Kanban, Error Proofing, Productive Maintenance, Set Up Time Reduction, Reduce Lot Sizes, Line Balancing, Schedule Leveling, Standardized work, and Visual Management. Six Sigma : Recognize, Define, Measure, Analyze, Improve, Control, Standardize, and Integrate. 5s 5S is a lean practice used to keep production workspace orderly and keep the workforce committed to maintaining order. 5S ( Japanese ) 5S ( English ) Definition Seiri Separate or Sort Separating needed tools, parts, and instructions from unnecessary items Seiton Set in Order Setting things in order, creating optimal boundaries, and locations for each item in a work area Seiso Shine Cleanliness of the work space after each day to maintain order Seiketsu Standardize Reminds people to conduct Seiri, Seiton, and Seiso to maintain the work place and pristine condition Shitsuke Sustain Ensuring that the organization has the discipline to sustain the habitat of sorting, organizing, and cleaning.
