What Is Quality assurance? Meaning & Nuclear Examples
Part of The Nuclear Dictionary | Get Into Nuclear
Quality assurance is the planned, systematic work that gives confidence that an item, process or service will meet its specified requirements.
Key takeaways
Quality needs to be built into the process.
Evidence demonstrates that requirements are met.
Quality assurance and inspection are related but different.
How it works
Quality assurance can include planning, competence, supplier arrangements, document control, reviews and audits. Quality control focuses on checking outputs against requirements. Both support delivery, with the extent of controls matched to the work and its significance.
An everyday analogy
Checking a cake after baking may reveal a problem. A reliable recipe, correct ingredients and controlled oven settings help prevent it. Inspection and a well-managed process each have a role.
Why it matters in nuclear work
Procurement teams specify evidence, engineers define acceptance requirements, and delivery teams retain records. A component that looks right may still be unacceptable if its identity, manufacture or conformity cannot be demonstrated.
Common misunderstandings
Quality is not simply the quality department’s responsibility. Nor does a large quantity of paperwork prove that the right requirements have been met.
