Lean Six Sigma
Lean Six Sigma is a management technique consisting of both Lean and Six Sigma techniques. This produces a methodology that relies on a collaborative team effort to improve performance by systematically removing waste (Lean) as well as defects, overproduction, waiting, non-utilized talent, transportation, inventory, motion and extra-processing (Six Sigma).
Lean production, often simply “Lean,” is a systematic method for the elimination of waste within a manufacturing process. Lean also takes into account waste created through overburden and waste created through unevenness in workloads. Working from the perspective of the client who consumes a product or service, “value” is any action or process that a customer would be willing to pay for.
Essentially, Lean is centered on making obvious what adds value by reducing everything else. Lean manufacturing is a management philosophy derived mostly from the Toyota Production System (TPS) and identified as “lean” only in the 1990s.
Six Sigma, like Lean, is used to improve the quality and efficiency of operational processes. During the past decade, these process improvement techniques increasingly have been applied outside of the manufacturing sector, for example, in healthcare.
While Lean focuses on identifying ways to streamline processes and reduce waste, Six Sigma aims predominantly to make processes, such as those used in clinical laboratories and pathology group labs, more uniform and precise through the application of statistical methods.
The principles were originally developed by Bill Smith of Motorola in 1986 as a way of eliminating defects in manufacturing, where a defect is understood to be a product or process that fails to meet customers’ expectations and requirements. The name refers to a quality level defined as the near-perfect defect rate of 3.4 defects per million opportunities. As a process improvement strategy, it gained much attention through its association with General Electric and its former CEO Jack Welsh.
This combined process improvement has become popular with clinical laboratories as a way to streamline laboratory processes and cut costs in a time when labs are increasingly pressured by downward price trends for lab tests. At the same time, labs are able to increase value offered to “customers,” that is, patients.
The Lean Six Sigma concepts were first published in a book titled Lean Six Sigma: Combining Six Sigma with Lean Speed by Michael George and Robert Lawrence Jr. in 2002. Training 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 karate.
