What this dot point is asking
WJEC wants you to understand quality in operations: why quality matters, the difference between quality control and quality assurance, the methods a business uses to maintain quality, and the benefits of producing high-quality goods and services. Quality is what protects the value a business has added, so poor quality undoes the work of the rest of the business.
Why quality matters
Quality control and quality assurance
This is the key distinction in the topic.
Methods of maintaining quality
The benefits of high quality
Why this matters
Quality protects the value added in production, so it links to marketing (quality supports branding and a premium price), to customer service and reputation, and to finance (poor quality raises costs through waste and returns). The choice of production method affects how quality is managed: flow production gives consistent quality, while job production relies on skilled workers. Exam questions often ask you to analyse the benefits of quality or the difference between control and assurance, where the link from quality to reputation, sales and costs earns the marks.

WJEC (Unit 1)3 marksExplain the difference between quality control and quality assurance.Show worked answer →
A 3-mark AO1 explain question. Reward a clear contrast with development.
Quality control means checking and inspecting products at the end of the production process to find and remove faulty ones before they reach the customer. It catches faults but only after they have happened, so resources are wasted on the rejects.
Quality assurance means building quality in at every stage of production, with each worker responsible for the quality of their own work, so faults are prevented rather than just caught. It aims to get it right first time and reduce waste. Markers reward the definition of each plus the key contrast of checking at the end versus building quality in throughout.
WJEC (Unit 1)6 marksAnalyse the benefits to a business of producing high-quality products.Show worked answer →
A 6-mark AO1 and AO3 analyse question. Reward developed benefits.
Benefit one: high quality builds a good reputation and customer loyalty, so customers return and recommend the business, raising sales and allowing it to charge a higher price.
Benefit two: good quality reduces waste, returns and complaints, which lowers costs and saves the time and money spent putting faults right.
Chain and judgement: high quality raises sales and lowers waste, improving profit, though maintaining it costs money in training and checks, so the benefit is greatest when better quality wins and keeps enough customers to justify the cost. Markers reward developed benefits plus a balanced comment.
