Lean Six Sigma takes the fundamental Six Sigma strategies for streamlining business processes and applies them alongside the “Lean” strategies of product production. The result is a hybrid system for making products, processes and services more effective and efficient.

The null hypothesis is the complement of the alternative hypothesis. The null hypothesis is what you anticipate through randomness. The alternative hypothesis, sometimes known as the alternate hypothesis is the opposite of that. It is what you would not anticipate by randomness. More often than not you are trying to reject the null because you are trying to see a change in something – considering that most Six Sigma projects are trying to fix broken processes.
Invented by engineering professor Kaoru Ishikawa, the seven basic tools of Six Sigma – sometimes referred to as the Ishikawa Tools – are simple but effective tools for solving quality …
The null hypothesis refers to the default prediction in research that no significant statistical relationship exists between two variables or two sets of data. The assumption in the null hypothesis …
The Andon Board, also known as an Andon Cord, is a status board usually erected high enough to ensure visibility by all of the factory workers.
Use: The Andon Board is a part of a visual factory. It is a way for everyone to see the status of the flow, and flow stoppages throughout the day. The concept started in Japan and is now used widely as a way to both visually see and sometimes hear when conditions change throughout the day.
The Ishikawa Tools (also known as Seven Basic Tools) are made up of the Cause-Effect Diagram, Check Sheet, Control Chart, Histogram, Pareto Chart, Scatter Diagram, and Stratification.
