Lean Six Sigma Glossary

The Seven Basic Quality Tools represent a list of basic process improvement tools and techniques. The list is generally attributed to Kaoru Ishikawa, a follower of Dr. Edwards Deming, who is also famous for popularizing the Fishbone or Ishikawa Diagram. In an effort to reduce the complexity of Statistical Process Control, and make it more accessible for the average worker,

TQC is a concept created by quality guru, Armand Feigenbaum, in the 1950s. He maintained that quality was not just the job of engineers or confined to production. TQC holds that every part of the company has to work in a coordinated way to serve the user or customer.

Total Quality Control is a concept created by quality guru, Armand Feigenbaum, in the 1950s. He maintained that quality was not just the job of engineers or confined to production. TQC holds that every part of the company has to work in a coordinated way to serve the user or customer.

The Theory of Constraints boils down to the idea that a process is only as good as its weakest link, and the weak links are bottlenecks. This idea was developed by Eliyahu Goldratt and made famous in his book, The Goal, a novel based on a production plant. Once the major bottleneck is discovered, the idea is to reduce or

The Taguchi Loss Function is an equation that measures the “loss” experienced by customers as a function of how much a product varies from what the customer finds useful. His idea rocked the quality world because the common wisdom at the time held that if products met internal measures they were “good” and if they fell outside the limits they

The Taguchi Methods consist of a 3-pronged quality approach developed by the Japanese statistician Genichi Taguchi. The focus was on Better design ideas Rigorous testing of the design Reducing the impact of anything that would cause variation His overall goal was to create a more robust product prior to full scale production. The Taguchi Methods were designed to deliver exactly

The Gemba Board is a method of collecting process issues and potential countermeasures that have been uncovered by the people working within the process. Once issues are surfaced they can be assigned to a person, a team or they may become the basis of a Rapid Improvement Event (aka Kaizen). Gemba Boards are also known as “Problem Boards,” “Waste Boards”

The Process Walk Board is a method of collecting process issues and potential countermeasures that have been uncovered by the people working within the process. Once issues are surfaced they can be assigned to a person, a team or they may become the basis of a Rapid Improvement Event (aka Kaizen). Process Walk Boards are also known as “Problem Boards,”

A Kanban Board is relative of the Kanban cards (Kanban is Japanese for “signpost”) that were originally developed to aid production at Toyota. Instead of “cards” the Kanban Board uses sticky notes or other visuals to represent tasks. These visual tasks move through different lanes to indicate where they are in a workflow. The simplest form of a Kanban Board
