Course Information
Understanding Variation Training
Learners will be able to:
- Describe how variation exists in everything and explain why process and product variation are undesirable.
- Measure variation using a histogram as well as statistically.
- Identify patterns of variation and explain their underlying causes.
About This Course
Variation is at the root of all quality problems. After all, if there was no variation, we would simply need to target our process on the ideal standard and everything we produce would come out exactly the same. But, that ideal world doesn’t exist. In reality every process has many variables such as time, temperature, tool wear and technique that affect the output of the process. So, a key goal in quality improvement is to reduce variation and the first step in doing that is to understand that variation in our processes.
This courses is a primer in the statistics used for SPC (Statistical Process Control); topics covered include building and using a histogram to understand variation, patterns of variation, measures of variation (mean, range, standard deviation), the normal curve and process stability. Both graphical and mathematical techniques of measuring variation are covered. This course is a targeted training course and provides focused training on concepts of variation that serve as the foundation of control charts. For comprehensive training on how to use control charts and their underlying principles, we recommend our Basic SPC online training.
This Course is Derived from Basic SPC Training This course is a great way to quickly learn about variation and how it is measured. It is taken from our comprehensive Basic SPC course. If you have already taken that Basic SPC Training course, you have already seen the content in Understanding Variation.
