Question

The most frequent error made by top management, when dealing with system variation, is:

A. Treating common causes as special causes

B. Considering all causes to be local causes

C. Recognizing that common causes require quick action

D. Treating special causes as common causes

Answer 1

Answer: Option D - Treating special causes as common causes

Explanation: Common causes of variation or random variation are the factors that cause a variation that is steady and around the mean of the data. On the other hand, special causes of variation cause the data to go beyond upper and lower data limits. One of the frequent errors made by the top management while dealing with system variation is treating special causes as the common ones.
