Achieving quality production | IGCSE Class 10 Business Studies Notes

This note covers what quality means in a business context and why it matters, the concept of quality control and how businesses carry it out, and the concept of quality assurance and how it is implemented, including how the two approaches compare.

What does quality mean in business?

In business studies, quality means a product or service that is fit for its purpose and meets the standard that the customer expects.

A good or service has good quality if it does the job it was designed to do reliably, looks and feels the way the customer expects, and is free from defects.

Quality is judged by the customer, not just by the business, so a product can only be described as good quality if it satisfies the needs and wants of the people who buy it.

Quality is not the same as being expensive or luxurious. A low-priced product can have excellent quality if it reliably does what it promises, and an expensive product can have poor quality if it breaks down or fails to meet the customer's expectations.

Fitness for purpose is therefore the key test: does the product do what it is meant to do, consistently, every time it is bought?

Why is quality important for all businesses?

Quality is important for every type of business because it affects whether customers buy from the business again and whether they recommend it to others.

Good quality builds customer satisfaction and loyalty, which helps a business keep its existing customers and attract new ones through recommendation. Poor quality can lead to complaints, returned goods, lost sales and damage to the business's reputation.

Quality also affects a business's costs. Poor quality can create extra costs such as wastage of materials, the cost of rework on faulty items, refunds to customers, and the cost of dealing with complaints.

If quality problems are not corrected, a business may lose customers to competitors who offer more reliable products.

In markets where many businesses sell similar products, quality can give a business a competitive advantage over rivals, because customers will choose the business whose goods or services they trust most.

Quality is also linked to a business's brand image. A business that is known for consistently high quality can often charge a higher price and build a stronger, more trusted brand than competitors whose quality is unreliable.

For these reasons, maintaining quality is a concern for every department of a business, not only the production department.

Definition: Quality. A product or service that is fit for its purpose and meets the standard that the customer expects, consistently and reliably.

What is quality control?

Quality control is the process of checking goods or services during and after production to find and remove any items that do not meet the required standard before they reach the customer.

Under quality control, inspectors check samples or batches of output, often at the end of the production process, and reject or correct any items that are faulty.

Quality control usually relies on a separate team of inspectors rather than the workers who made the product.

Checks may be carried out at various stages, for example checking raw materials when they arrive, checking work in progress during production, and checking the finished product before it is sent to customers.

If items fail the check, they can be reworked, scrapped or sent back to be corrected.

Advantages of quality control

• Faulty goods are identified before they reach the customer, which protects the business's reputation.
• Having specific inspectors to check quality means workers on the production line can focus on producing output quickly.
• It can be applied without needing every worker to be retrained, since inspection is carried out by a separate team.

Limitations of quality control

• Faults are found only after production, so materials, labour and time have already been spent making defective items, which is wasteful.
• It relies on inspectors checking samples, so some defective items may not be checked and could still reach the customer.
• It does not necessarily address the root cause of the fault, so the same mistake may be repeated in future output.
• Employing inspectors adds to the cost of production.

Definition: Quality control. Checking goods or services, usually by inspectors, during and after production to find and remove items that do not meet the required standard.

What is quality assurance?

Quality assurance is a system of procedures, set up throughout the whole production process, that aims to prevent faults from happening in the first place rather than only finding them afterwards.

Under quality assurance, every worker is responsible for checking the quality of their own work as they go along, and procedures are agreed in advance that every stage of production must follow.

The aim of quality assurance is often described as "getting it right first time", meaning that the business tries to design its systems and train its workers so that defects do not occur at all, instead of relying on inspectors to catch them later.

This requires a quality culture within the business, where all employees, not just inspectors, see maintaining standards as part of their job.

Implementing quality assurance usually involves setting clear standards or procedures for every stage of production, training workers so that they understand and can meet those standards, giving workers responsibility for checking their own output, and reviewing and improving the procedures when problems are found.

Because responsibility is shared throughout the workforce rather than concentrated in an inspection team, quality assurance aims to build quality into the process rather than inspecting it in afterwards.

Advantages of quality assurance

• Preventing faults before they happen reduces wastage of materials, labour and time compared with finding faults only at the end.
• Because every worker checks their own work, responsibility for quality is shared across the whole workforce, which can improve motivation.
• It encourages a quality culture that can improve the reputation of the business over the long term.

Limitations of quality assurance

• Setting up agreed standards and procedures for every stage of production, and training workers to follow them, can take time and cost money.
• Workers may not always follow procedures correctly, so some faults can still occur even with a quality assurance system in place.
• It depends on all workers being committed to maintaining standards, which can be difficult to achieve if staff are not well trained or motivated.

Definition: Quality assurance. A system of agreed procedures and standards covering every stage of production, designed to prevent faults from occurring rather than only detecting them afterwards.

How do quality control and quality assurance differ?

Although both quality control and quality assurance aim to achieve good quality, they differ in when and how they act.

Quality control checks output after it has been produced and removes faulty items, while quality assurance tries to prevent faults from being produced in the first place by building standards into every stage of the process.

Quality control is usually carried out by a separate team of inspectors, whereas quality assurance makes every worker responsible for the quality of their own output.

In practice, many businesses use elements of both approaches. A business may set up clear standards and procedures through quality assurance to prevent most faults, while still using some quality control checks as a final safeguard before goods reach the customer.

For example, a business making packaged food might train workers to follow agreed hygiene and recipe procedures at every stage (quality assurance) while also having inspectors check a sample of finished packs before despatch (quality control).

Glossary

• Quality culture: a situation where all employees in a business take responsibility for maintaining quality standards.
• Inspection: the act of checking samples of output against required standards.
• Rework: correcting a faulty item so that it meets the required standard, instead of scrapping it.
• Wastage: materials, labour or time lost because output does not meet the required standard.
• Customer satisfaction: the degree to which a product or service meets or exceeds customer expectations.
• Reputation: the opinion that customers and others hold of a business, built up over time by its behaviour and output.
• Brand image: the way customers perceive a business or its products, often influenced by quality and reliability.
• Competitive advantage: an edge over rivals that helps a business attract and keep customers.

Common errors and misconceptions

• Misconception: Quality means a product is expensive or luxurious. Correct: Quality means the product is fit for its purpose and meets what the customer expects, regardless of price.
• Misconception: Quality control and quality assurance are the same thing. Correct: Quality control checks output after it is made; quality assurance sets up procedures throughout the process to prevent faults happening at all.
• Misconception: Quality is only the responsibility of the production department. Correct: Quality affects, and is affected by, every part of the business, from purchasing materials to dealing with customer complaints.
• Misconception: Quality control always removes every faulty item before it reaches the customer. Correct: Quality control usually relies on inspecting samples, so some faulty items can still reach customers undetected.
• Misconception: Quality assurance means workers no longer need any checks at all. Correct: Quality assurance still involves standards and procedures that workers must follow and that may be reviewed; faults can still occur if procedures are not followed correctly.
• Misconception: Improving quality has no cost to the business. Correct: Both quality control and quality assurance involve costs, such as employing inspectors or training workers and setting up procedures.

Exam-style questions with model answers

Q1. Define the term "quality" in a business context. [2 marks]

1. Quality means a product or service is fit for its purpose.
2. It means the product consistently meets the standard that the customer expects.

Q2. State two reasons why quality is important to a business. [2 marks]

1. Good quality encourages customer satisfaction and repeat purchase.
2. Poor quality can damage the business's reputation and lead to lost sales.

Q3. A small bakery currently checks its finished loaves by sampling a few from each batch after baking and throwing away any that are burnt or underweight. Explain two limitations of this method for the bakery. [4 marks]

1. By the time the loaves are checked, the ingredients, labour and oven time have already been used on the faulty loaves, so the bakery has already wasted resources on items it cannot sell.
2. Because only a sample is checked rather than every loaf, some faulty loaves may not be inspected and could still be sold to customers, risking complaints and harming the bakery's reputation.

Q4. Explain the difference between quality control and quality assurance. [4 marks]

1. Quality control involves checking output, usually by a separate team of inspectors, during and after production to find and remove items that do not meet the required standard.
2. Quality assurance is a system of agreed procedures and standards covering every stage of production, designed to prevent faults from happening in the first place.
3. Quality control therefore deals with faults after they occur, while quality assurance tries to stop faults occurring at all.
4. Under quality control, responsibility usually rests with inspectors, whereas under quality assurance every worker is responsible for checking the quality of their own work.

Q5. A clothing manufacturer currently relies only on inspectors who check finished garments at the end of the production line. The owner is considering introducing a quality assurance system where every machinist checks their own stitching as they work, alongside agreed stitching standards and extra training. Evaluate whether the manufacturer should introduce this quality assurance system. [6 marks]

1. Introducing quality assurance could reduce wastage, because faults in stitching would be identified by the machinist at the point they occur rather than only at the end of the line, after fabric, thread and labour time have already been used on the whole garment.
2. Giving machinists responsibility for checking their own work could improve their motivation, as they would see quality as part of their own job rather than something left entirely to inspectors.
3. Training workers and agreeing stitching standards would take time and cost money, and some machinists may not follow the new procedures consistently, so faults could still occur.
4. The manufacturer would probably still want to keep some final inspection as a safeguard, since quality assurance reduces but does not guarantee the complete elimination of faults.
5. On balance, if the manufacturer can afford the training cost and the workforce is willing to take on the extra responsibility, introducing quality assurance alongside some final checks would likely reduce wastage and improve reputation over time, so the manufacturer should introduce it.

Q6. Outline one advantage and one limitation of using only quality control to maintain standards in a factory. [3 marks]

1. One advantage is that having a separate inspection team means production workers can focus on producing output quickly without also having to check quality themselves.
2. One limitation is that faults are only found after production, so materials and labour may already have been wasted on defective items, and some faulty items may still slip through if only samples are checked.

Key takeaways

• Quality means a product or service is fit for its purpose and consistently meets what the customer expects.
• Quality matters because it affects customer satisfaction, repeat sales, reputation, costs and competitive advantage.
• Quality control checks goods or services during and after production and removes items that fail to meet the standard.
• Quality control usually uses separate inspectors and can leave wastage from faults found too late.
• Quality assurance sets up procedures and standards across the whole production process to prevent faults occurring at all.
• Quality assurance gives every worker responsibility for checking their own work, aiming for "right first time".
• Quality assurance can reduce wastage compared with quality control, but setting it up takes time, training and cost.
• Many businesses combine both approaches, using agreed procedures to prevent most faults and inspection as a final safeguard.

Test yourself

What does "fitness for purpose" mean?

It means a product reliably does the job it was designed to do, which is a key test of whether it has good quality.

Who usually carries out the checks under quality control?

Quality control checks are usually carried out by a separate team of inspectors, who check samples or batches of output during or after production.

What is the main aim of quality assurance?

Quality assurance aims to prevent faults from happening in the first place, often described as "getting it right first time", rather than only finding faults afterwards.

Give one cost that poor quality can create for a business.

Poor quality can create costs such as wasted materials, rework on faulty items, refunds to customers or lost future sales.

How does responsibility for quality differ between quality control and quality assurance?

Under quality control, responsibility usually rests with inspectors; under quality assurance, every worker is responsible for checking the quality of their own output.

Why might a business use both quality control and quality assurance together?

Quality assurance procedures can prevent most faults occurring, while quality control checks act as a final safeguard to catch any faults that still slip through before goods reach customers.
