In the context of this text, quality is defined not as "luxury," but as "conformance to specifications." A $10,000 watch and a $10 watch can both be high quality if they meet their respective design standards perfectly. The role of Statistical Quality Control (SQC) is to ensure that this conformance is consistent, predictable, and cost-effective.
