On 100 Years of the Shewhart Control Chart

In this Statistically Speaking, Bill Woodall and Annie Dudley provide a non-mathematical overview of process monitoring methods, ranging from their introduction by Walter Shewhart in the Industry 2.0 era to the challenges now faced in Industry 4.0.

The duo also explores the use of variable components, regression-adjusted monitoring methods, and profile monitoring while acknowledging that – in a rising number of cases – monitoring methods should be desensitized, which is counter to the prevailing research quest for increased sensitivity in detecting smaller process changes.

Learn:

• The difference between process monitoring methods when first introduced in the Industry 2.0 era and the challenges faced in Industry 4.0.
• Why it is important for monitoring methods to be desensitized.
• How monitoring methods have been adapted to account for larger amounts of data, changes in data structure, and increased computing power.
