The relationship between the natural variation in the production system and the product's design specifications can be quantified using:
A)Six sigma
B)Control charts
C)A process capability index
D)Fishbone diagrams

Question

Quizplus · Accepted Answer

A process capability index (such as Cp or Cpk) is used to evaluate the ability of a production process to consistently meet the design specifications of a product. It takes into account both the natural variation of the process and the tolerance limits of the product. Six Sigma and control charts are also useful tools in process improvement, but they do not specifically quantify the relationship between natural variation and product design specifications. Fishbone diagrams are a tool for identifying and analyzing the causes of problems in a process, but do not directly relate to quantifying the relationship between natural variation and product design specifications.
