Definition
The process of confirming before implementation that the proposed design of equipment, a system or a solution meets user, regulatory and intended-use requirements.
Human Explanation
DQ asks whether the right solution has been designed.
Why it Matters
Design errors are usually most difficult and expensive to correct at later stages.
Conceptual Boundary
DQ evaluates the design, not the installed equipment or its operation.
Practical Perspective
DQ reviews user needs, technical specifications, intended use and applicable requirements before implementation begins.
