We at Key Man Lock & Safe Company are proud to announce our Master Locksmith, Glenn Letteer has completed Six Sigma/Lean Six Sigma Master Black Belt Certification.
Six Sigma at many organizations simply means a measure of quality that strives for near perfection. Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving toward six standard deviations between the mean and the nearest specification limit) in any process – from manufacturing to transactional and from product to service.
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 & 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.
