A quality process or product conforms to requirements.

This definition is ideal for quality assurance teams that need to validate processes, systems, services and product quality. Working from requirements, they can easily validate conformance and identify non-conformance.

5. Quality is a Standard

The manufacturing industry was the first to take a hard, scientific look at quality. Manufacturers are concerned both with the quality of products and the quality of the manufacturing process itself.

Manufacturers use standards and continual process improvement methodologies to improve both processes and product quality. They view quality in terms of measurements and statistics.

Experiences are measured by establishing relationships with customers to elicit dialog and feedback. Experience quality can also be measured by bottom line metrics such as revenue, return visits and lifetime customer value.
