The concept of quality
Quality means meeting the expectations of the customer. That definition matters, because quality is not the same as expensive: a budget hotel is high quality if it delivers exactly what it promised for the price. A luxury hotel that leaves a room uncleaned is low quality, whatever it charges.
Quality applies to services as well as goods, and the specification asks about both. In a service, quality is about consistency, reliability, staff knowledge and how customers are treated — and it is harder to control, because a service is produced by people in the moment rather than checked before it leaves a factory.

Why quality matters
The specification names two reasons: controlling costs, and gaining a competitive advantage.
Controlling costs. Good quality reduces costs, which sounds contradictory until the alternative is counted. Poor quality means wasted materials on products that must be scrapped, time spent reworking faults, refunds and replacements for customers, and the cost of handling complaints. Preventing faults is almost always cheaper than fixing them — which is the argument for quality assurance over quality control.
Gaining a competitive advantage. Quality gives customers a reason to choose this business over a rival, and to come back. It supports a higher price, because customers will pay more for something they trust. It generates recommendations, which cost nothing. And it protects reputation, which is slow to build and quick to lose.
The cost of poor quality is worth stating plainly, because evaluation questions turn on it: a dissatisfied customer does not simply fail to return — they tell others, and online they can tell a great many.
Worked example
A manufacturer currently inspects finished goods and scraps around 8% of output. It is considering switching to quality assurance. Evaluate this.
- Identify the current cost: 8% of everything made is wasted, so materials and labour are being spent on output that earns nothing.
- Explain the change: quality assurance makes each worker responsible for checking their own stage, so a fault is caught immediately rather than after the item is finished.
- State the gain: far less material and labour wasted, because faults are found before more work is added — and inspectors may no longer be needed.
- State the cost: training every worker takes time and money, and the system takes a while to become effective.
- Reach a judgement using the numbers given.
Answer: Worth doing. Scrapping 8% of output is a substantial and recurring waste of materials and labour, and quality assurance catches faults at the stage they occur rather than after all the work is done. The cost is training and a period of disruption while it beds in — a one-off cost against a saving that repeats on every batch.
Common mistake
Quality means meeting customer expectations, not being expensive or luxurious. A cheap product that does exactly what it promised is high quality; a costly one that disappoints is not.
Before you practise
- Quality means meeting customer expectations — not being expensive.
- Quality applies to services as well as goods, and is harder to control in services.
- Quality control checks at the end; quality assurance builds quality in throughout.
- Control is simpler but wasteful; assurance reduces waste and motivates staff but needs training.
- Good quality controls costs by avoiding waste, rework, refunds and complaints.
- Preventing faults is cheaper than fixing them.
- Quality gives competitive advantage through loyalty, higher prices, recommendations and reputation.
- A dissatisfied customer does not just fail to return — they tell others.
