Go to Customer Service (GCSE Business)What is Quality Assurance & Control?
Quality control is the process of inspecting products to ensure they meet the required standards, often by checking a sample of items at the end of the production line. Quality assurance is a broader, proactive approach that aims to build quality into the production process itself to prevent defects from occurring in the first place.
Board notes: Covered by all major boards (AQA, Edexcel, OCR). The distinction between quality control and quality assurance is a key concept that is frequently examined. Students should be able to explain the benefits of improving quality.
Step-by-step explanationWorked example
A car factory uses quality control by having inspectors check a sample of finished cars for scratches or defects. It uses quality assurance by training all its staff in Total Quality Management (TQM), empowering them to spot and fix potential quality issues at every stage of the assembly line, not just at the end.

Common mistakes
- 1Using the terms quality control and quality assurance interchangeably. Control is about detection (finding errors), while assurance is about prevention (stopping errors from happening).
- 2Thinking quality control means checking every single product. This is often impractical (100% inspection), so businesses usually check a random sample. The key is to ensure the sample is representative.
- 3Believing that high quality always means high cost. While using better raw materials might cost more, a good quality assurance system can reduce waste and the costs associated with customer complaints and returns, saving money in the long run.
