Improving quality can strengthen customer perceptions, reduce waste and help a business compete, but achieving higher quality can also increase costs and create operational difficulties. This The value and difficulties of improving quality A-Level Business revision page examines the benefits of higher quality, the consequences of poor quality and why quality is not equally important to every competitive strategy. It builds directly on quality control and quality assurance [Quality control and quality assurance] and develops the quality objective introduced in operational objectives [Operational objectives]. AQA specifically requires students to understand both the benefits and difficulties of improving quality and the consequences of poor quality.

The value and difficulties of improving quality A-Level Business revision overview
AQA's operational management specification requires students to understand:
methods of improving quality, including quality assurance versus quality control
the benefits and difficulties of improving quality
the consequences of poor quality.
Throughout operational management, students must also consider how operational decisions affect the competitiveness of the business.
Quality therefore matters because it can affect both sides of business performance:
what customers are prepared to buy and pay
how efficiently the business produces its output.
What does improving quality mean?
Improving quality means increasing the extent to which the product, service or operational process achieves the standard required by the business and its customers.
Quality does not automatically mean making a product luxurious or expensive.
The required standard depends on the context.
For example, different customers may value:
reliability
consistency
service
punctuality
particular features of the product or service.
AQA's 2025 Paper 2 demonstrates this contextual approach clearly. Students were asked how an airline would benefit from being the best in its market on its chosen quality measures, including punctuality and complaints.
📌 Exam point: Avoid writing about "quality" as though it means exactly the same thing for every business. Identify what good quality means in the context provided.
Why businesses may improve quality
Improving quality can create several connected benefits.
AQA assessment material identifies potential effects including:
increased perceived value
increased sales
the ability to charge higher prices
more price-inelastic demand
reduced wastage
lower unit costs
stronger profit margins
competitive advantage.
The key examination skill is to turn one of these ideas into a developed chain of reasoning.
Improved quality and perceived value
Higher quality may make customers perceive a product as providing greater value.
The chain may be:
quality improves
↓
customers perceive the product as more valuable
↓
the product becomes more attractive to customers
↓
demand or sales may increase
↓
revenue may increase
↓
profit may rise, depending on the costs of achieving the quality improvement
AQA's 2025 mark scheme recognises that better quality can enhance perceived value and lead to higher sales and profit.
This also links back to added value as an operational objective.
Improved quality and added value
Improved quality may increase the value customers attach to the output.
If that increase in perceived value is greater than the additional resources required to produce the improvement, the business may increase its added value.
A possible chain is:
higher quality
↓
customers perceive more value
↓
added value increases
↓
business may gain greater scope to charge a higher price
↓
profitability may improve
AQA has repeatedly assessed the relationship between quality and added value. In the 2022 Paper 1, students were expected to recognise that improving quality could increase added value.
Improved quality and higher prices
Customers may be willing to pay a higher price when they believe the quality of a product has improved.
AQA's 2023 mark scheme identified this as an important route by which quality can improve profitability.
The possible chain is:
quality improves
↓
customers perceive greater value
↓
customers become more willing to pay a higher price
↓
business raises price
↓
difference between price and unit cost may increase
↓
profitability may improve
This depends on customers genuinely valuing the improvement.
If customers are unwilling to pay more, the higher-quality product may simply have cost more to provide without creating sufficient additional revenue.
This creates a natural link with pricing decisions [Pricing decisions].
Quality and price elasticity of demand
Improving quality may make demand more price inelastic.
AQA directly tested this relationship in the 2024 Paper 1. Students were expected to recognise that a business might improve quality to make demand more price inelastic and to achieve a competitive advantage.
If customers value the quality strongly, they may become less responsive to a change in price.
A possible chain is:
higher quality
↓
customers place greater value on the product
↓
customers become less sensitive to price
↓
demand becomes more price inelastic
↓
business may have greater ability to charge a higher price
↓
revenue or profit may increase
Do not write that improved quality means demand becomes perfectly inelastic. The point is that demand may become more price inelastic.
Improved quality and sales volume
Quality may also increase profit by increasing the quantity sold rather than by increasing price.
AQA's 2023 mark scheme recognised improved quality as one possible cause of higher sales volume.
For example:
higher-quality product
↓
customers prefer it to competing products
↓
sales volume increases
↓
total revenue rises
↓
total profit may rise
Again, this depends on what happens to costs.
Higher sales do not automatically mean higher profitability if the quality improvement has made the product substantially more expensive to provide.
Improved quality and customer satisfaction
If customers receive the level of quality they value, customer dissatisfaction may fall.
AQA's 2025 airline question recognised that strong punctuality could:
reduce customer dissatisfaction
reduce complaints
encourage repeat business.
A general chain is:
quality improves
↓
product or service better meets customer requirements
↓
customer satisfaction improves
↓
customers may be more likely to buy again
↓
future sales may be supported
This can be particularly valuable where repeat purchases are important.
Improved quality and customer loyalty
Consistent quality can encourage repeat purchases.
For example:
business consistently provides the required quality
↓
customers become satisfied with previous purchases
↓
customers return to the business
↓
repeat sales increase
↓
business may need to spend less attracting replacement customers
AQA's 2025 Dodo mark scheme recognised exactly this logic. Lower complaints may indicate satisfied customers, leading to repeat business and reducing the need to spend as much attracting new customers.
Quality can therefore have both:
a revenue effect
a potential cost effect.
Improved quality and reputation
Strong quality may contribute to a better reputation.
AQA's 2025 Dodo mark scheme recognised that fewer complaints could contribute to a better reputation and competitive advantage.
The chain could be:
high quality
↓
customers have positive experiences
↓
fewer complaints and stronger reputation
↓
business becomes more attractive relative to competitors
↓
demand may increase
↓
competitive position strengthens
Reputation is particularly important where customers have several alternative businesses from which to choose.
Improved quality and competitive advantage
A competitive advantage exists when a business has an advantage that helps it compete more successfully against rivals.
Quality may create this advantage if customers perceive the business's output as better than competitors' output in ways they value.
AQA's 2024 Paper 1 explicitly tested the statement that a business might improve quality in order to achieve a competitive advantage.
The possible chain is:
business provides superior quality
↓
customers value the difference
↓
business is differentiated from competitors
↓
customers choose the business rather than rivals
↓
competitive advantage is created
Quality therefore can be particularly important where a business competes through differentiation.
Improved quality and differentiation
AQA's 2023 mark scheme recognised that a differentiation strategy normally depends on customers perceiving some form of uniqueness, which is likely to involve higher-quality products or perceived quality.
Therefore:
higher quality
↓
greater perceived difference from competitors
↓
stronger differentiation
↓
customers may accept a higher price
↓
profitability may improve
This relationship becomes especially important later in the course when considering strategic positioning.
Improving the quality of processes
Quality is not only about improving the characteristics of the final product.
AQA's 2023 mark scheme refers to improving the quality of the product or process of providing a product.
Improving process quality may reduce errors and waste.
For example:
better operational process
↓
fewer defects
↓
less wasted output
↓
total costs may fall
↓
unit costs may fall
↓
profit margins may increase
This means improving quality can sometimes support a low-cost strategy, not just differentiation.
Quality and lower wastage
Reducing defective output can be a major benefit of quality improvement.
AQA's 2025 quality mark scheme recognises lower wastage as a route to lower unit costs and increased profit margins.
The chain is:
quality improved
↓
fewer defective products
↓
less output wasted
↓
fewer resources used producing unusable output
↓
unit costs fall
↓
profit margins may rise
This is especially relevant to the right-first-time principle studied in quality control and quality assurance [Quality control and quality assurance].
Quality and unit costs
Students sometimes assume improved quality must increase unit costs.
That is too simplistic.
Quality improvement can cause unit costs to fall if it reduces waste and makes the process more efficient.
For example:
Before improvement:
total costs = £2,000,000
usable output = 100,000 units.
$$
\text{Unit cost}=\frac{£2,000,000}{100,000}=£20
$$
After improved process quality:
total costs = £2,070,000
usable output = 115,000 units.
$$
\text{Unit cost}=\frac{£2,070,000}{115,000}=£18
$$
Although total costs increased by £70,000, the cost per usable unit fell from £20 to £18.
Improving the process has increased effective output proportionately more than total costs.
Quality and profitability
Quality can contribute to profit through either side of the profit relationship.
Revenue route
higher quality → greater perceived value → higher price or higher sales → higher revenue → potentially higher profit
Cost route
higher quality process → less wastage → lower unit costs → higher margin → potentially higher profit
AQA's 2023 and 2025 mark schemes both recognise these routes.This makes quality a potentially powerful operational objective.
However, it is not guaranteed to improve profitability.
Difficulties of improving quality
The specification explicitly requires students to understand that improving quality can be difficult.
Businesses must therefore compare the expected benefits with the cost and practical difficulty of achieving them.
Quality improvements can cost money
A business may need additional resources to achieve higher quality.
Depending on the approach, this can include:
employee training
quality inspection
changes to operational processes.
AQA's 2025 mark scheme identifies the cost of employee training when using quality assurance and the cost associated with inspection teams under quality control.
Therefore:
business improves quality system
↓
additional resources required
↓
operating costs rise
↓
unit costs may increase
↓
profit falls unless the quality improvement creates sufficient additional revenue or other cost savings
The key issue is whether the benefit exceeds the cost.
The tension between higher quality and higher costs
The 2023 examiner report noted that students frequently focused successfully on the tension between higher quality and higher costs.
This is a central evaluation issue.
For example:
higher-quality inputs or more expensive quality processes
↓
costs rise
↓
business may need to raise its price
↓
customers may not be willing to pay the higher price
↓
sales may fall
The quality improvement is only valuable if customers value it sufficiently.
Customers may not value the improvement
AQA's 2025 mark scheme explicitly notes that quality improvement may be undesirable or unnecessary if customers are not prepared to pay a higher price for it.
Suppose a business spends heavily improving a feature that customers barely notice.
Then:
quality improvement
↓
costs increase
but:
customers perceive little additional value
↓
price or sales cannot increase sufficiently
↓
profitability may fall
Managers therefore need to know which aspects of quality customers actually value.
Quality improvement can require training
A business using quality assurance may need employees to understand their responsibility for achieving quality.
This can require training.
The chain is:
quality improvement programme
↓
employees require training
↓
training costs money and takes time
↓
short-term operating costs rise
↓
quality gains must be sufficiently large to justify the investment
This was explicitly recognised in the 2025 QA versus QC mark scheme.
Quality improvement may require cultural change
If employees previously saw quality as someone else's responsibility, changing to a system in which everyone focuses on quality can be difficult.
AQA's 2025 quality mark scheme identifies business culture and leadership style as factors influencing the effectiveness of different quality approaches.
The possible chain is:
business changes approach to quality
↓
employee responsibilities change
↓
existing culture may not support the new approach
↓
employees may not implement it effectively
↓
expected quality improvement may not occur
The success of quality improvement therefore depends partly on the people implementing it.
Employees may still make mistakes
Quality assurance aims for right-first-time working, but AQA's 2025 mark scheme recognises that expecting every employee to avoid mistakes may be unrealistic.
Therefore:
business relies heavily on employees preventing faults
↓
employee makes an error
↓
fault is not prevented
↓
poor-quality output may still be produced
An improvement method is therefore not guaranteed to eliminate all quality problems.
Quality improvements may take time
Changing operational methods or employee behaviour may not produce immediate results.
In the short term:
training may be required
existing processes may be disrupted
costs may rise.
The longer-term benefits may include:
less wastage
more consistent quality
stronger customer demand.
This gives an important evaluation distinction:
short-term cost versus longer-term benefit.
Improved quality may conflict with a cost objective
Businesses have several operational objectives [Operational objectives], and these may conflict.
If management prioritises quality:
additional resources devoted to quality
↓
costs may rise
↓
cost objective becomes harder to achieve
A business competing primarily through very low prices may therefore judge the value of further product-quality improvements differently from a differentiated business.
However, remember that process quality can also reduce waste and lower costs.
The quality-cost relationship can work in both directions.
Quality improvement and investment decisions
A business may need to invest resources to maintain or enhance the source of its competitive advantage.
AQA's 2025 assessment of competitive advantage recognised continued investment as one of several difficulties businesses can face in maintaining an advantage.
For quality, this means managers need to judge whether continued expenditure on quality produces enough:
customer value
cost savings
competitive benefit.
The business should not improve quality simply for the sake of improvement.
Consequences of poor quality
The specification explicitly requires students to understand the consequences of poor quality.
These consequences can affect:
customers
costs
revenue
reputation
competitiveness.
Poor quality and customer dissatisfaction
If output fails to achieve the quality customers expect:
poor-quality product or service
↓
customer expectations are not met
↓
customer dissatisfaction increases
↓
complaints may increase
AQA's 2025 Dodo mark scheme supports the reverse relationship, recognising that higher punctuality can avoid customer dissatisfaction and reduce complaints.
Poor quality can therefore create a direct customer-service problem.
Poor quality and complaints
Complaints require the business to deal with dissatisfied customers.
In the 2025 Dodo context, AQA recognised lower complaints as a benefit of strong quality performance.
The reverse chain is therefore:
poor quality
↓
more dissatisfied customers
↓
more complaints
↓
business must devote more resources to dealing with problems
↓
costs may increase
The exact consequences will depend on the nature of the business.
Poor quality and additional customer-related costs
AQA's 2025 airline mark scheme identified lower compensation payments as a possible benefit of reducing complaints and delays.
In an appropriate context:
poor service quality
↓
more complaints or failures
↓
additional costs associated with dealing with affected customers
↓
profit may fall
Do not assume the same specific cost applies in every industry. Use only costs justified by the information in the question.
Poor quality and reputation
Poor quality can damage a business's reputation.
AQA's 2025 mark scheme directly linked lower complaints with a better reputation and competitive advantage.
The reverse relationship is:
poor quality
↓
negative customer experiences
↓
reputation deteriorates
↓
potential customers may become less willing to choose the business
↓
sales may fall
↓
competitive position weakens
The significance is likely to be greater where customers have many alternatives.
Poor quality and repeat business
Satisfied customers may buy again.
Poor quality can threaten this repeat business.
The possible chain is:
customer receives poor-quality output
↓
customer becomes dissatisfied
↓
customer chooses a competitor in future
↓
repeat sales fall
↓
business must attract replacement customers
↓
revenue and profit may be affected
AQA's 2025 Dodo mark scheme recognises repeat business as a benefit of higher quality, particularly where customers make repeated purchases.
Poor quality and wastage
Poor process quality may mean greater amounts of defective output are created.
The chain is:
poor operational quality
↓
more defective output
↓
more wastage
↓
resources have been used without generating usable output
↓
unit costs rise
↓
profit margins may fall
AQA's 2025 quality mark scheme directly recognises decreasing wastage as a route through which improved quality can reduce unit costs.
This relationship is particularly important for operational analysis.
Poor quality and unit costs
Consider a simplified example.
A factory incurs costs of £1,000,000.
Situation A
Usable output = 100,000 units.
$$
\text{Unit cost}=\frac{£1,000,000}{100,000}=£10
$$
Situation B
Poor quality means only 80,000 usable units result from the same £1,000,000 expenditure.
$$
\text{Unit cost}=\frac{£1,000,000}{80,000}=£12.50
$$
Unit cost has increased from £10 to £12.50 per usable unit.
The poor-quality process means productive resources are generating less saleable output.
Poor quality and competitiveness
Poor quality may weaken competitiveness in two ways.
Revenue effect
poor quality → customer dissatisfaction → weaker reputation/repeat business → lower demand
Cost effect
poor quality → wastage → higher unit costs → weaker cost competitiveness
This means quality can influence both:
differentiation
cost performance.
Quality as a source of competitive advantage
Quality is especially important when customers can distinguish between rival products or services on the basis of quality.
For example:
business achieves better quality than rivals
↓
customers perceive a meaningful difference
↓
business gains competitive advantage
↓
sales, loyalty or pricing power may improve
AQA's 2024 Paper 1 explicitly recognised improved quality as a way of achieving competitive advantage.
AQA's 2025 Dodo question then required students to analyse the benefit of being the best in the market on particular quality measures.
Being better than competitors matters
Quality is not only about meeting a minimum standard.
Where quality forms part of competitive positioning, the business may gain more value by performing better than competitors.
The Dodo mark scheme provides examples:
better punctuality may attract customers who value arriving on time
fewer complaints may improve reputation
satisfied customers may generate repeat business.
The key point is:
relative quality can matter to competitive advantage.
A business does not compete against an abstract quality standard. It competes against alternatives available to customers.
Quality and low-cost competition
Quality is not equally important in the same way to every competitive strategy.
AQA's 2023 mark scheme recognised that a business using a low-cost strategy may place less emphasis on improved product quality but may depend on higher-quality operational processes to reduce costs.
This distinction is important.
Product quality
A low-cost business may not need to make its product substantially more sophisticated if customers mainly value low prices.
Process quality
Avoiding mistakes and wastage may still be extremely important because this helps keep unit costs low.
Therefore, saying:
"Quality is unimportant to a low-cost business"
would be too simplistic.
Quality and differentiated competition
A differentiated business is more likely to rely heavily on customer perceptions of quality.
AQA's 2023 mark scheme recognised that differentiation normally requires customers to perceive greater value or uniqueness.
The chain is:
higher quality
↓
stronger perceived difference
↓
greater customer value
↓
demand may become less price sensitive
↓
business may charge a higher price
↓
profitability may improve
Quality may therefore be particularly important when it is central to the reason customers choose the business.
Quality is not the only source of competitiveness
Students should avoid arguing that quality always determines competitive success.
AQA's 2023 mark scheme explicitly recognised that profit can be improved through factors other than quality, including lower costs and marketing activity.
A business may compete using other operational objectives such as:
cost
speed of response
flexibility.
Therefore, the importance of quality should be evaluated relative to what customers value in that market.
The nature of the market matters
The value of improving quality depends on customer expectations and competition.
AQA's 2025 quality mark scheme identifies the importance of quality to the customer and the level of competition as factors relevant to evaluating quality decisions.
Quality may be especially important where:
customers can easily compare competitors
customers make repeat purchases
customer expectations are high
quality differences are visible or important
poor quality makes switching to a competitor likely.
It may be less valuable to make costly improvements that customers neither notice nor value.
Quality and price
Improving quality may allow a higher price, but only if customers perceive sufficient additional value.
Suppose:
current selling price = £50
current unit cost = £35
contribution towards fixed costs and profit per unit = £15.
After quality improvement:
new unit cost = £40.
If the business can raise its price to £60:
$$
£60-£40=£20
$$
The amount per unit available towards fixed costs and profit has increased from £15 to £20.
But if customers refuse to pay more and the price remains £50:
$$
£50-£40=£10
$$
The amount per unit has fallen from £15 to £10.
The same quality improvement can therefore have very different consequences depending on customer response.
Quality and sales
A similar issue applies to sales volume.
Improved quality may increase sales if customers value the improvement.
However:
quality improves
does not automatically mean:
sales increase.
Sales may also depend on:
price
promotion
competition
market conditions.
AQA's 2023 mark scheme explicitly noted that increased sales may arise from quality but can also be caused by other factors, such as improved marketing.
This is why extended answers should avoid single-cause assumptions.
Quality and other business functions
AQA requires students to consider the interrelationship between operational decisions and other functions.
Marketing
Better quality may:
strengthen perceived value
influence positioning
support higher prices
encourage customer loyalty.
Finance
Improving quality may:
require expenditure
reduce unit costs through less wastage
affect revenue and profit.
Human resources
Quality improvement may require:
training
increased employee responsibility.
These interrelationships can strengthen analysis when they remain focused on the question.
How to assess whether improving quality is worthwhile
A business should compare:
The expected benefit
Will improved quality create:
greater customer value
increased sales
higher prices
fewer complaints
greater repeat business
lower wastage
lower unit costs
stronger competitive advantage?
The difficulty or cost
Will the improvement require:
expensive training
more costly processes
additional inspection
cultural or organisational change?
Customer response
Will customers actually value the improvement?
Competitive context
Is quality an important reason customers choose between businesses?
The decision is worthwhile when the likely benefits are greater than the costs and difficulties.
Quality can support both differentiation and cost efficiency
One of the most important ideas for evaluation is that quality has two possible competitive roles.
Differentiation route
better product/service quality
↓
greater customer value
↓
higher price or greater sales
↓
competitive advantage
Efficiency route
better process quality
↓
fewer errors and less waste
↓
lower unit costs
↓
greater cost competitiveness
This is why quality can matter even to businesses that are not competing through premium products.
Building a strong quality analysis chain
A weak answer:
Better quality means more customers.
A stronger response:
business improves the quality feature customers value
↓
customers perceive the product as superior to competing products
↓
demand becomes stronger and potentially more price inelastic
↓
business may raise its selling price
↓
profit margin may increase
↓
competitive position improves
Every stage answers the question: why does quality matter?
Building a cost-based quality chain
better operational process
↓
fewer defective products
↓
less wastage
↓
lower unit costs
↓
business can offer a more competitive price or retain a greater margin
↓
competitiveness improves
This shows that quality and efficiency do not always conflict.
Building an argument about poor quality
poor quality
↓
customer expectations are not met
↓
complaints and dissatisfaction increase
↓
business reputation deteriorates
↓
repeat business falls
↓
sales and competitive position may weaken
This is much stronger than simply writing:
Poor quality is bad for reputation.
Building a counterargument
A strong evaluation might challenge the assumption that more quality is always better:
business spends heavily improving quality
↓
unit costs rise
↓
customers do not value the additional improvement
↓
business cannot increase price or sales sufficiently
↓
profitability falls
↓
resources may have been better used elsewhere
This turns the discussion from "quality is good" into an actual business judgement.
Assessing the importance of quality to competitiveness
When the question asks how important quality is, consider:
What do customers value?
Is quality a major purchasing criterion?
How does the business compete?
Is it mainly differentiated by quality or focused heavily on low costs?
How does its quality compare with competitors?
Being better than competitors may generate competitive advantage.
What are the consequences of failure?
Could poor quality lead to complaints, lost repeat business or higher costs?
How expensive is improvement?
Would the quality gains justify the expenditure?
Is process quality or product/service quality more important?
A low-cost business may still need excellent process quality to minimise waste.
The strongest answers usually end with a contextual condition rather than a universal statement.
Example evaluative judgement
A weak conclusion:
Quality is very important because customers like high-quality products.
A stronger conclusion:
Quality is likely to be most important to competitiveness when customers can distinguish clearly between rival products and are willing to pay more for superior quality. In this situation, improved quality can strengthen differentiation, loyalty and pricing power. However, where customers mainly prioritise a low price, further expensive improvements to product quality may be less valuable. Even then, good process quality remains important because reducing mistakes and waste can help the business maintain low unit costs.
That judgement weighs both customer value and operational cost.
Key Words 🔑
Key word | Student-friendly definition | How it may be used in an exam |
Quality | The standard achieved by a product, service or operational process relative to what is required. | Analyse how meeting or exceeding the required standard affects customers and performance. |
Wastage | Resources or output that do not contribute effectively to usable or saleable output. | Explain how better quality may reduce unit costs by lowering waste. |
Customer satisfaction | The extent to which the product or service meets customers' expectations. | Analyse how quality may affect complaints, repeat purchases and demand. |
Competitive advantage | An advantage that helps a business compete more successfully against rivals. | Assess whether superior quality gives customers a reason to choose the business. |
Price inelastic demand | Demand where the percentage change in quantity demanded is proportionately smaller than the percentage change in price. | Explain how stronger perceived quality may make customers less sensitive to price. |
Hints from the Examiner Reports 💡
Examiner hint: Develop the tension between quality and cost rather than assuming that quality improvement is automatically beneficial. The 2023 examiner report noted that many successful responses focused on the relationship between higher quality and higher costs.
Examiner hint: Quality can improve profit through several routes. AQA's 2023 mark scheme recognises higher prices, increased sales and improvements to process quality that reduce costs. Choose the route that fits the question and develop it fully.
Examiner hint: Quality does not need to be the only way to improve performance. The 2023 mark scheme explicitly recognised alternative routes to improved profit, so avoid conclusions that treat quality as universally essential.
Examiner hint: Use quality measures in context. In 2025, AQA expected students to explain how specific quality outcomes such as punctuality and fewer complaints would benefit the business, rather than discussing quality generically.
Examiner hint: Strong analysis reaches a final business consequence. For example, do not stop at "fewer complaints". Develop this into reputation, repeat business, reduced costs or competitive advantage where the context supports it.
Examiner hint: In evaluative answers, the final judgement should follow from the arguments developed. AQA's quality mark schemes do not assume one universal conclusion because the value of quality depends on factors such as customer expectations, competition, workforce skills and the nature of the product.
Common Mistakes ⚠️
Mistake: Assuming improved quality always increases profit
Why this is incorrect: Improving quality can increase costs. Profit will only improve if the increase in revenue or reduction in other costs is sufficiently large.
How to improve: Develop both sides:
quality benefit
versus
cost of achieving it.
Mistake: Assuming higher quality always means higher unit costs
Why this is incorrect: Better process quality can reduce errors and wastage, which may lower unit costs.
How to improve: Distinguish between:
improvements that require greater expenditure
improvements that make the process more efficient.
Mistake: Treating quality as the same thing as luxury
Why this is incorrect: Quality is about achieving the standard required by customers and the business.
How to improve: Use the context to identify what customers actually value.
Mistake: Saying quality makes demand price elastic
Why this is incorrect: AQA has tested the opposite relationship. Improved quality may make demand more price inelastic because customers place greater value on the product.
How to improve: Remember:
stronger perceived quality → potentially less price-sensitive customers → more price-inelastic demand.
Mistake: Assuming better quality automatically means more sales
Why this is incorrect: Customers must value the improvement, and sales can also be affected by price, marketing and competition.
How to improve: Use conditional wording:
Sales may rise if the quality improvement makes the product more attractive to the target market.
Mistake: Describing poor quality without developing the consequence
Why this is incorrect: Writing "poor quality causes complaints" is only the beginning of the analysis.
How to improve: Develop the chain:
poor quality → complaints → weaker reputation → less repeat business → lower sales → weaker competitiveness.
Mistake: Assuming quality is irrelevant to a low-cost business
Why this is incorrect: A low-cost business may place less emphasis on premium product quality, but good process quality can reduce defects, wastage and unit costs.
How to improve: Distinguish between:
product/service quality
process quality.
Mistake: Ignoring competition
Why this is incorrect: Quality is most valuable as a competitive advantage when it gives customers a reason to choose one business over another.
How to improve: Compare the business with its rivals and ask whether the quality difference matters to customers.
Mistake: Assuming any quality improvement is worth its cost
Why this is incorrect: AQA's 2025 mark scheme recognises that improvement may not be worthwhile if customers are unwilling to pay for greater quality.
How to improve: Ask:
Does the customer value the improvement enough to justify what it costs the business?
Exam-Style Questions ✍️
Question 1
Which one of the following is a possible benefit of improving the quality of a product?
A. Demand necessarily becomes more price elastic
B. Customers may become less sensitive to price
C. Unit costs must increase
D. Capacity utilisation must fall
[1 mark]
Answer: B.
Question 2
Explain one possible benefit to a business of improving quality.
[3 marks]
Indicative answer:
Improved quality may increase the value customers perceive in the product. Customers may therefore be more willing to buy it or pay a higher price, which could increase revenue and profit if the extra revenue is greater than the cost of improving quality.
Question 3
Explain one possible consequence of poor quality for a business.
[4 marks]
Indicative answer:
Poor quality may leave customers dissatisfied and increase complaints. This could damage the business's reputation, making customers less likely to purchase from it again. As a result, future sales may fall.

poor quality → customer/business consequence → effect on performance.
Question 4
A manufacturer spends £1.8 million producing 100,000 units. Poor quality means that 10,000 units cannot be sold.
Calculate the cost per saleable unit.
[3 marks]
Answer:
Saleable output:
$$
100,000-10,000=90,000\text{ units}
$$
Cost per saleable unit:
$$
\frac{£1,800,000}{90,000}=£20
$$
Answer: £20 per saleable unit
Mark guidance:
1 mark for identifying 90,000 saleable units.
1 mark for correct division.
1 mark for £20 per saleable unit.
Question 5
PrimeCoffee Ltd improves the quality of its drinks. Unit cost rises from £2.20 to £2.60, but managers believe customers will be willing to pay more for the improved product.
Analyse one way the quality improvement could increase PrimeCoffee Ltd's profitability.
[9 marks]
Indicative content:
Unit cost has risen by £0.40, so the quality improvement has created a cost.
Customers may perceive the improved drink as providing greater value.
This may make demand more price inelastic.
PrimeCoffee may therefore be able to increase its selling price.
If the increase in price per drink is greater than the £0.40 increase in unit cost, the amount earned per unit towards profit could increase.
The business may therefore become more profitable despite higher production costs.
Higher-level answers should not simply state that higher quality means higher profit.
Question 6
SkyLink Ltd operates passenger services in a highly competitive market.
Its performance data are:
Quality measure | SkyLink | Main competitor |
Services arriving on time | 93% | 82% |
Complaints per 10,000 customers | 18 | 41 |
Analyse how SkyLink Ltd's quality performance may give it a competitive advantage.
[9 marks]
Indicative content:
SkyLink has a much higher proportion of services arriving on time, 93% compared with 82%.
Customers who place a high value on punctuality may prefer SkyLink.
Fewer complaints, 18 rather than 41 per 10,000 customers, may indicate higher customer satisfaction.
More satisfied customers may be more likely to purchase from SkyLink again.
The quality difference may improve reputation.
This can provide customers with a reason to choose SkyLink rather than the competitor.
SkyLink may therefore gain a competitive advantage.
Mark guidance:
Higher-level responses should use the contextual data and develop the effect on competitiveness.
Question 7
ValueHome Ltd competes mainly by offering low-priced standardised products. Managers are considering spending heavily to increase the quality of the materials used in its products.
Analyse one reason why this quality improvement may not improve ValueHome Ltd's competitiveness.
[9 marks]
Indicative content:
ValueHome competes mainly through low prices.
Higher-quality materials may increase unit costs.
The business may need to increase its prices to maintain its margin.
Customers who mainly choose ValueHome because of price may not value the quality improvement sufficiently.
They could switch to a cheaper competitor.
The investment may therefore weaken rather than strengthen ValueHome's existing competitive position.
Alternatively, students may analyse why improved process quality could still support a low-cost position by reducing wastage.
Question 8
CraftStyle Ltd makes premium home furnishings.
Managers are considering a programme to improve quality.
Current data:
Measure | Current position | Forecast after improvement |
Unit cost | £80 | £92 |
Average selling price | £130 | £155 |
Defective output | 6% | 2% |
Annual sales | 40,000 units | 43,000 units |
The programme requires employee training and changes to production methods.
Assess whether improving quality is likely to strengthen CraftStyle Ltd's competitiveness.
[16 marks]
Arguments supporting the programme may include:
Defective output is forecast to fall from 6% to 2%, suggesting less poor-quality output.
Lower wastage may improve operational efficiency.
Average selling price is forecast to rise from £130 to £155, an increase of £25.
Unit cost rises by £12, from £80 to £92.
The selling-price increase is therefore larger than the unit-cost increase.
Customers may be willing to pay the higher price because CraftStyle already operates in a premium market.
Forecast sales also increase from 40,000 to 43,000 units.
Higher perceived quality may strengthen differentiation from competitors.
Arguments against or reasons for caution may include:
Unit costs rise by 15%:
$$\frac{£92-£80}{£80}\times100=15%$$
The programme requires training and changes to production.
The forecast selling price and sales increase depend on customers genuinely valuing the improvement.
If customers do not accept the £155 price, the increase in costs could reduce competitiveness.
Competitor quality and prices will also influence the value of the improvement.
Evaluation:
The forecasts provide a strong case for improvement because defective output falls substantially while the expected selling-price increase exceeds the increase in unit cost. The premium positioning also suggests that customers may place significant value on quality.
However, the programme strengthens competitiveness only if customers perceive enough extra value to accept the higher price. The most important issue is therefore customer response relative to the additional cost of quality.
Question 9
"Improving quality is the most important way for a business to become more competitive."
To what extent do you agree?
[25 marks]
Indicative content:
Arguments supporting the statement:
Better quality can increase perceived value.
Customers may be prepared to pay higher prices.
Demand may become more price inelastic.
Higher quality may increase sales.
Strong quality may improve reputation.
Greater customer satisfaction may create repeat business.
Better quality than rivals may create competitive advantage.
Better process quality may reduce defects and wastage.
Lower wastage may reduce unit costs and improve cost competitiveness.
Arguments challenging the statement:
Improving quality may increase costs.
Customers may not value the additional quality sufficiently.
Higher unit costs may require higher prices.
Businesses competing mainly on low prices may gain more from improving cost efficiency.
Other operational objectives, such as speed of response and flexibility, may be more important to some customers.
Marketing activity can also affect sales and perceived value.
A business may improve profit without improving quality.
The importance of quality varies according to competition, product type and customer expectations.
Evaluation:
Quality can be a major source of competitiveness where customers value superior products or services and can distinguish clearly between competitors. It may allow higher prices, stronger loyalty and differentiation.
However, quality is not automatically the most important factor. A low-cost business may gain more from maintaining efficient processes and low unit costs, while another market may place greater value on speed or flexibility.
Even in a low-cost business, good process quality may remain crucial because reducing errors and waste supports lower unit costs.
The strongest judgement should therefore identify what customers value and how the business intends to compete. Quality is most important where it creates customer value or operational savings large enough to outweigh the cost and difficulty of achieving it.
