Managing quality
Businesses manage quality in two ways: quality control checks finished products for faults, while quality assurance builds quality into every stage of production. High quality controls costs and gives a competitive advantage.

What Is Quality?
A quality product meets or exceeds customers' expectations - and does so every time.
-
Fit for purpose
It does what customers need it to do.
-
Consistent
Every product is made to the same standard.
-
Not the same as luxury
A cheap product can be high quality if it meets the expectations of customers who buy it.
-
Services too
Quality applies to service - speed, friendliness and reliability.
Quality Control or Quality Assurance?
Quality control
- Checking finished products for faults, usually at the end of production.
- Done by specialist inspectors.
- Faulty products are thrown away or reworked.
- Finds problems after they have happened.
- Can be wasteful: materials and time are lost on every faulty product.
Quality assurance
- Checking quality at every stage of production.
- Every worker is responsible for their own work.
- Aims to prevent faults happening in the first place.
- Less waste, as faults are caught early.
- Needs training, and staff who care about quality.
Checking Every Detail
Quality control inspectors check finished products, or a sample of them, before they are sent to customers. It stops faulty products reaching customers - but by the time a fault is found, the materials and time have already been used.
Quality control: inspecting finished products for faults.
The Importance of Quality
-
Controlling costs
Fewer faulty products means less waste, fewer returns and less money spent fixing mistakes.
-
Competitive advantage
A reputation for quality helps a business stand out from rivals and win customers.
-
Premium prices
Customers will often pay more for a product they trust to be well made.
-
Customer loyalty
Customers who get good quality every time come back and recommend the business.
The Cost of Poor Quality
When quality fails, the costs mount up quickly.
-
Waste
Faulty products must be scrapped or reworked.
-
Returns and refunds
Customers return faulty goods and demand their money back.
-
Product recalls
Dangerous faults can force a business to recall every product sold - extremely expensive.
-
Reputation
Bad reviews and news stories drive customers away for years.
Case study
The Galaxy Note 7 Recall
In August 2016 Samsung launched the Galaxy Note 7 smartphone. Within weeks, reports emerged of phones overheating and catching fire because of faulty batteries. Airlines banned the phone from flights. Samsung recalled millions of phones, and when replacement phones also caught fire, it stopped making the Note 7 altogether in October 2016. The failure cost Samsung billions of dollars and damaged its reputation - a clear example of how poor quality can cost far more than getting it right would have done.
Build Quality In
A sandwich factory has had complaints about missing ingredients and wrong labels. Design a quality assurance system for it: list three checks at different stages of production, and explain how each would prevent the problem rather than just finding it.
1. One check when ingredients arrive.
2. One check during assembly.
3. One check at labelling.
4. How each prevents problems.
A good answer shows: Three checks at different stages (ingredients arriving, assembly, labelling) with each explained as preventing faults.

Question 4 Analyse 6 marks
Source: SmartHome Ltd makes wireless doorbells. It uses quality control, with inspectors checking one in every 50 doorbells at the end of the production line. Last year 4% of doorbells were returned faulty, and its online reviews have fallen from 4.5 to 3.2 stars. Analyse the impact of poor quality on SmartHome Ltd.
Show answerHide answer
Model answer
A 4% return rate means SmartHome is refunding or replacing many doorbells, which increases its costs, as each faulty doorbell is paid for twice - once to make and again to replace. Because inspectors only check one in every 50 doorbells, faulty products are reaching customers. The fall in online reviews from 4.5 to 3.2 stars will also affect sales. Customers read reviews before buying, so a low rating will push them towards competitors. This means SmartHome's sales and revenue are likely to fall at the same time as its costs rise, reducing its profit.
Mark scheme
- AO2 (Application, 3 marks): uses the context - 1 in 50 checks, 4% returns, 4.5 to 3.2 stars — Level 1-3
- AO3a (Analysis, 3 marks): chains of reasoning about costs, reputation and sales — Level 1-3
