Section 5.3: factors of production

The four factors

Factor	Meaning	Example in a bakery
Enterprise	Owner or entrepreneur who takes risk and organises the other inputs	The owner deciding to open a second shop
Capital	Equipment, machinery, vehicles, tools and technology used to make output	Ovens, mixers, delivery van
Land	Site, premises and natural resources	The shop and bakery unit; flour as a farm product
Labour	People who work for the business	Bakers, counter staff

Key idea: the specification talks about changing relationships. The mix of the four can change, and a business can swap one input for another.

Why the mix changes

• New technology makes machines cheaper or more capable.
• Wages rise relative to equipment prices, or the reverse.
• The business grows and can afford equipment.
• The business changes where it sells, for example online instead of on the high street.
• The entrepreneur takes on loans and fixed costs and so more risk.

Capital-intensive and labour-intensive

	Capital-intensive	Labour-intensive
Uses	A high proportion of capital to labour	A high proportion of labour to capital
Largest cost	Equipment, depreciation, running costs	Wages
Examples	Car plant, refinery, bottling line	Salon, care home, tailor
Strength	Consistent, high-volume output; lower cost per unit at scale	Flexible, personal service, lower fixed costs
Weakness	High fixed costs, expensive to change	Wage costs, less consistent output

Test: compare the cost of capital with the cost of labour in the data, using labour cost divided by total cost multiplied by 100.

Method: showing a change in mix

1. Work out each cost as a percentage of total costs, before and after.
2. Work out cost per unit (total costs divided by output) before and after.
3. Work out output per worker (output divided by number of workers).
4. Comment on fixed costs and risk.
5. Reach a judgement for this business.

Small reminder: wages 60,000, equipment 20,000, other 20,000. Labour share = 60,000 ÷ 100,000 × 100 = 60%, so labour-intensive. If equipment rises to 50,000 and wages fall to 30,000 with other costs unchanged, total costs are 100,000 and capital is the largest share (50%).

Section 5.4: quality

Key definitions

Term	Meaning
Quality	How well a good or service meets or exceeds customer expectations and the business’s own standard
Quality control	Checking output against a standard and removing or correcting faulty items, usually by inspection
Total quality management (TQM)	Approach in which everyone is responsible for quality; the aim is prevention and getting things right first time
Competitive advantage	Something that makes customers choose your business rather than a rival

Quality in goods and in services

• Goods: reliability, durability, finish, safety. Faulty items can be reworked, scrapped or returned.
• Services: speed, accuracy, friendliness, consistency. A mistake is seen by the customer as it happens, and staff behaviour is part of the product.

Quality control or TQM

	Quality control	TQM
Responsibility	Inspectors, quality department	Every employee
Focus	Finding faults	Preventing faults
When	At checkpoints, often at the end	Throughout the process
Costs	Inspection, wasted materials already used	Training, change in culture, time
Risk	Faults found late	Needs staff commitment to work

Features of TQM to quote: shared responsibility, prevention, training, a customer focus (internal and external), and continuous improvement.

Quality control methods

• Inspect every item, or a sample from each batch.
• Check at several stages: materials in, work in progress, finished goods.
• For services: mystery customers, call monitoring, customer surveys.

How quality gives a competitive advantage

1. Reputation and recommendations.
2. Ability to charge a higher price.
3. Lower costs from less waste, rework and returns.
4. Customer loyalty and repeat sales.

Method: cost of defects

1. Defective units = output × defect rate.
2. Cost = defective units × cost per defective unit.
3. Saving = old cost − new cost.
4. Payback time = one-off cost ÷ saving per period.

Small reminder: 2,000 units, 5% defective, 8 per defective unit. Defective units = 100; cost = 800. At 2% the cost is 40 × 8 = 320, a saving of 480. A one-off cost of 2,400 would be recovered in 5 periods.

Must-know distinctions

• Capital here means equipment and technology, not just cash.
• Capital-intensive is about the balance of capital and labour in the business, not about its size.
• Quality control detects faults; TQM prevents them.
• Quality is judged against customer expectations, so it can differ between a budget and a luxury business and still be good in both.
• A competitive advantage needs customers to notice and value the quality, and it needs to be kept up.

Command words for this topic

The specification describes how each command word is used. Apply them like this.

Command word	What the specification asks for	Applied here
Define	Define a term from the content	Give a short, accurate meaning of capital-intensive, quality control or TQM
Calculate	Use the data given, show workings	Labour share of costs, defect cost, output per worker
Outline	Two linked points, placed in the context of the question	A change in the mix of inputs, then its effect on this business
Explain	A statement of fact with two expansion points; no context in the question	One reason quality matters, then two linked consequences
Analyse	Extended answer, expanding a concept or issue in the context given	A chain of reasoning from cause to effect to the business
Justify	Extended answer using the information to recommend one of two options	Choose one option and say why, using the figures
Evaluate	Extended answer reaching a supported conclusion	Weigh both sides, then decide for this business

A short model chain for analysis

Starting point: a toy maker buys a cutting machine. Chain: machine does the cutting, so each worker produces more, so cost per toy falls, so the business can cut prices or earn more profit. Then add the other side: the machine’s cost is fixed, so if orders fall the owner still pays it. Always link back to the business named.

A short model chain for evaluation

Question type: should a small clinic introduce TQM? Gains: fewer complaints, less rework, a better reputation. Costs: staff time on training, possible resistance, results that take months. Judgement: yes if the clinic can afford the training and has a stable team, because the gains keep growing while the cost is mostly one-off. Say what the judgement depends on.

Goods and services side by side

	Goods	Services
Quality measures	Defect rate, returns, durability	Waiting time, complaint rate, accuracy
Quality control	Inspect batch or sample	Mystery customer, survey, call review
TQM example	Operators stop the line when they spot a fault	Every member of staff trained to solve a customer problem on the spot

Quick self-test

1. Name the four factors of production listed in the specification.
2. State what is meant by a labour-intensive activity.
3. A firm’s wages are 72,000 out of total costs of 160,000. Calculate the labour share of costs.
4. Give two reasons why a business might replace some labour with capital.
5. Give one risk for the entrepreneur when a business becomes more capital-intensive.
6. State what quality control means.
7. Name two features of TQM.
8. A firm makes 4,000 items, with a 3% defect rate and a cost of 15 per defective item. Calculate the total cost of defects.
9. Explain one way better quality can allow a business to charge a higher price.
10. State one disadvantage of relying only on end-of-process inspection.

Answers

1. Enterprise, capital, land, labour.
2. An activity that uses a high proportion of labour compared with capital, so wages are the main cost.
3. 72,000 ÷ 160,000 × 100 = 45%.
4. For example: machines produce more output per worker; wages are rising faster than equipment prices; machines give more consistent output.
5. Fixed costs rise, so the entrepreneur still pays them if sales fall; more borrowing may be needed.
6. Checking output against a standard and removing or correcting items that fail, usually by inspection.
7. For example: everyone responsible for quality; prevention of faults; staff training; customer focus; continuous improvement.
8. 4,000 × 0.03 = 120 items; 120 × 15 = 1,800.
9. Customers see the product as reliable and better than rivals, so more of them accept a higher price, which raises revenue per unit.
10. Faults are found after the materials and labour have been used, so waste has already happened.

Where marks are usually lost

• Defining capital as money rather than equipment and technology.
• Calling a business capital-intensive without comparing capital and labour costs.
• Describing quality control and TQM in the same words.
• Giving general benefits of quality that do not use the scenario.
• Leaving out the cost side of quality when asked to evaluate or justify.
• Not giving a conclusion that is supported by the data.
• Dividing by the wrong total when finding percentages.
• Saying robots always cut costs without mentioning fixed costs, training and risk.

Frequently asked questions

What are the four factors of production in Edexcel IGCSE Business? The 4BS1 specification names enterprise, capital, land and labour. These are the inputs a business combines to make goods or provide services.

What is the difference between quality control and TQM? Quality control uses inspectors to check products against a standard and remove faults at set stages. Total quality management makes everyone responsible for quality and aims to prevent faults at source, getting things right first time.

Why does the mix of factors of production change? Technology, the relative cost of labour and equipment, growth, changes in location or sales channel and the risk the entrepreneur will accept can all push a business to use more of one input and less of another.

How do you calculate the cost of defects? Multiply output by the defect rate to find the number of faulty items, then multiply by the cost of reworking or scrapping each one.
