Module 4 - Background
FROM: George Washburn
SUBJECT: Quality Project
As you know, EMC recently hired a Quality Assurance Manager who is developing a QA Department. How we were able to go for so long without a formal quality department is a mystery and I must accept responsibility for it. But we are on the road to quality and quality assurance. Your next project will be to assist this new manager when she arrives, which will be in about two weeks. The exact assignment will be out in my next email.
Let me know if you have any questions

Definitions of quality
What is quality? What do we mean we say that this or that has quality, or is good or bad, or is excellent, etc.? We are talking about how this particular thing, action, process, or concept, fulfills the intent of its existence. Some things are designed by humans, others occur in nature. Consider what you say is a "good" apple. It grows on trees, but still there is some set of characteristics that we think about when we consider what makes it "good". It is sweet, juicy, fresh, crunchy, has no worms, etc. It is supposed to grow that way. Now consider an object that is designed and produced - say a computer. It starts up quickly, runs software without delays or bugs, performs the tasks it is programmed to do, displays the information with clarity on the screen, etc. This product is designed and built and its characteristics are specified beforehand. How do we think about these specifications of quality?
The nine dimensions & six levels provide a good way of thinking about characteristics of quality. Click Here
Process capability is a fundamental concern of product quality. In manufacturing, the finished product often is assembled from various components. These components must fit together in the right way. Each part is designed with certain target specifications and a small amount of “wiggle room” or tolerances. Processes must produce the part within the range of tolereances. This Wikipedia page has some good background information:

How can you tell if a process is in control? Once a process has been determined to be capable, you need to have a way to keep track of it, at least for a period of time. Statistical process control and control charts is one way.

What is Total Quality Management (TQM) and creating a culture of quality?

Six Sigma is one of the newer quality movements. It is based on process capability and requires that a process be able to operate within +/- six standard deviations (sigma).
This document explaining the revolution of Six Sigma also presents the infrastructure and roles of the MBB, BB and GB.

The Six Sigma methodology is well rooted in statistics and statistical mathematics. Learn why six standard deviations is worthwhile for your organization to measure.
