Common Causes of Variation and Process Quality | TQM/LSS/SPC Lecture in PDF

YouTube Video

The quality of a process is highly dependent on the common causes of variation in the process. By reducing the common causes of variation in the process over time we can improve the process quality significantly.

Chapters included;

1. Causes of Variation (Introduction)
2. What do we mean by common causes of variation?
3. How do the common causes enter into the process?
4. How do we identify the common causes of variation in the process?
5. Can we eliminate the common causes of variation?
6. What about the pattern of variation in the process due to common causes?
7. What do we understand by a stable process?
8. What do we understand by a predictable process?
9. How many data values are lying between (+/-)1Sigma, (+/-)2Sigma, (+/-)3Sigma for a normal distribution?
10. Study of the bowling variation of a fast bowler due to common causes?
11. How can we improve the process quality?
12. Glan McGrath (The Man of Line, Length, Bounce, and Yorker) An example of significant improvement in process quality by reducing common causes
