In Six Sigma terminology, what does CTQ refer to?

CTQ stands for "Critical to Quality," and it refers to the key attributes or requirements that are essential for meeting customer expectations and ensuring the quality of a product or service. These elements are determined based on customer needs and specifications, which makes them vital in enhancing overall customer satisfaction.

Identifying CTQs involves understanding what is most significant to the customer and ensuring that these quality metrics are achieved in the process. By focusing on these critical attributes, organizations can prioritize their improvement efforts, optimize processes, and ultimately deliver higher-quality products or services that align with customer expectations. This concept is foundational in the Six Sigma methodology, where data-driven decision-making is crucial for continuous improvement and operational excellence.
