Revision Notes 📚
Quality control and quality assurance A-Level Business revision overview
AQA places this topic within making operational decisions to improve performance: improving quality.
The specification requires students to understand:
methods of improving quality
quality assurance versus quality control
the benefits and difficulties of improving quality
the consequences of poor quality.
This lesson concentrates specifically on the two methods of improving quality.
The wider consequences of higher and lower quality are developed in the value and difficulties of improving quality [The value and difficulties of improving quality].
What is quality?
In operational management, quality concerns whether a good or service achieves the standard required by the business and its customers.
Quality should not automatically be confused with:
high price
luxury
complex products.
A lower-priced product can still achieve the quality standard required of it.
The important issue is whether the business consistently provides the standard customers expect.
Quality was introduced as one of the possible operational objectives [Operational objectives]. Businesses therefore need a method for achieving and maintaining that objective.
Two approaches required by AQA are:
quality control
quality assurance.
What is quality control?
Quality control (QC) is an approach in which output is inspected or checked so that products that do not meet the required quality standard can be identified before reaching customers.
The emphasis is therefore on checking output.
AQA's 2025 mark scheme emphasised that quality control is geared towards preventing faulty products from leaving the business.
A simplified process is:
Goods or services are produced.
Output is inspected or checked.
Output that fails to meet the required standard is identified.
The business aims to stop sub-standard output reaching customers.
The central idea is:
produce → inspect → identify faults
The purpose of quality control
Quality control provides a way of detecting problems with output.
If a faulty product is identified before sale:
fault identified during inspection
↓
product prevented from reaching the customer
↓
customer is less likely to receive defective output
↓
potential damage associated with poor quality may be avoided
Quality control therefore aims to protect customers and the business from the consequences of faulty products leaving the operation.
Quality control and inspection
Quality control places significant importance on inspection.
The business needs a way to assess whether output meets the required standard.
In some businesses, responsibility for identifying faulty output may therefore be separated from the employees who originally produced it.
AQA's 2025 mark scheme contrasts this with quality assurance by referring to an inspection team within quality-control systems.
The key distinction is that quality is checked, rather than every employee necessarily being given responsibility for preventing problems throughout the process.
Advantages of quality control
Faulty products can be identified before reaching customers
This is the main strength.
If inspection identifies a defect:
fault detected
↓
faulty output does not leave the business
↓
customer receives output that meets the required standard
↓
risk of customer dissatisfaction may fall
This can be especially valuable where preventing defective goods from reaching customers is a major priority.
AQA's 2025 mark scheme explicitly recognised this as a potential advantage of QC over QA.
Quality control may require less training
AQA's 2025 mark scheme recognises that QC may involve less training than quality assurance.
This is because responsibility for quality checking can remain concentrated in the inspection process rather than requiring every employee to take responsibility for achieving quality throughout operations.
The possible chain is:
less employee training required
↓
lower training costs
↓
QC may be cheaper to introduce
↓
particularly valuable if QA would only create a small additional improvement in quality
This makes QC potentially suitable where the additional benefits of a full quality-assurance approach would be limited.
Quality control can provide a final safeguard
A key advantage of inspection is that it can act as a final check before output reaches customers.
This can be important because employees may make mistakes regardless of how carefully a process is designed.
AQA's 2025 mark scheme recognised that QA relies on workers avoiding mistakes, whereas QC specifically focuses on preventing faulty products from leaving the business.
This gives QC a possible advantage where identifying faulty final output is especially important.
Difficulties with quality control
Faults may already have occurred
Quality control identifies problems after output has been produced or during the inspection of output.
If a product is found to be faulty, the business has already used resources creating it.
This can create waste.
The possible chain is:
product made incorrectly
↓
inspection detects defect
↓
resources have already been used producing the faulty item
↓
wastage increases
↓
unit costs may rise
Quality control can therefore stop a faulty product reaching the customer without necessarily preventing the waste associated with producing it.
Employees may see quality as someone else's responsibility
One difficulty identified explicitly in AQA's 2025 mark scheme is that workers may regard quality as the inspector's job.
The possible consequence is:
employees believe inspectors are responsible for quality
↓
employees place less emphasis on preventing defects themselves
↓
more sub-standard output may be produced
↓
greater reliance on inspection
↓
wastage and costs may increase
This is one of the strongest contrasts with quality assurance.
Inspection itself creates costs
A business using quality control may require employees whose role includes checking output.
These employees represent an operational cost.
AQA's 2025 mark scheme notes that quality assurance may remove the need for a separate inspection team, creating potential cost savings.
Therefore, one potential disadvantage of QC is:
separate inspection activity
↓
additional employee cost
↓
higher operating costs
↓
potential pressure on profit margins
The significance depends on how expensive the inspection process is.
What is quality assurance?
Quality assurance (QA) is an approach in which responsibility for achieving quality is built into the operational process, with employees responsible for ensuring quality as work is carried out.
Rather than depending primarily on faults being identified through a later inspection stage, the aim is to prevent faults from occurring.
AQA's 2025 mark scheme associates quality assurance with:
greater employee responsibility
a right-first-time philosophy
quality forming part of everyone's role.
The central idea is:
build quality into the process → prevent faults rather than relying on finding them afterwards
Right first time
AQA explicitly links quality assurance with the philosophy of right first time.
This means trying to complete activities correctly when they are first undertaken.
The aim is to avoid:
errors
faulty output
reworking activities
unnecessary waste.
The possible chain is:
right-first-time approach
↓
fewer defects are produced
↓
less output needs correcting or discarding
↓
waste falls
↓
unit costs may fall
↓
profitability may improve
This relationship also connects quality assurance with some of the efficiency principles considered in lean production [Lean production].
Everyone has responsibility for quality
Under a quality-assurance approach, responsibility for quality is not left solely to a separate inspection function.
Instead, employees have responsibility for ensuring quality within their own work.
The possible effect is:
employees take responsibility for quality
↓
problems are prevented or identified as part of the process
↓
fewer defective products are produced
↓
quality may become more consistent
AQA's 2025 mark scheme specifically identifies consistent quality as a potential advantage because everyone's role incorporates a focus on quality.
Quality assurance and employee responsibility
Giving employees greater responsibility for quality may also affect motivation.
AQA's 2025 mark scheme recognises greater worker responsibility as one potential motivational benefit of quality assurance.
A possible chain is:
employees given responsibility for quality
↓
greater responsibility may increase motivation
↓
employees take greater care in their work
↓
fewer mistakes may occur
↓
quality and productivity may improve
However, this depends on how employees respond to the additional responsibility.
Advantages of quality assurance
Fewer defects and less wastage
The right-first-time philosophy aims to prevent mistakes before they become defective final products.
Therefore:
faults prevented during the process
↓
less defective output created
↓
less wastage
↓
lower unit costs
↓
potential improvement in profit
This is one of the most important arguments in favour of QA.
More consistent quality
If quality is part of everyone's role, the focus on required standards runs throughout the operation rather than being concentrated at the end.
AQA's 2025 mark scheme recognises that this may lead to more consistent quality levels.
More consistent quality may mean customers are more likely to receive the standard they expect repeatedly.
This may strengthen the business's competitiveness where quality matters strongly to customers.
Potential savings on inspection
If employees themselves take responsibility for achieving quality throughout operations, a separate inspection team may be unnecessary or less important.
The chain could be:
quality built into employees' work
↓
less need for separate inspection
↓
inspection-related employee costs may fall
↓
operating costs may fall
↓
profit margins may increase
AQA's 2025 mark scheme specifically recognises this potential saving.
Potential motivational benefits
Greater responsibility may make employees feel more involved in the quality of the final output.
If this increases motivation:
greater responsibility
↓
higher motivation
↓
employees take greater care
↓
quality improves
↓
fewer defects and potentially stronger customer satisfaction
This benefit is not guaranteed because employees respond differently to additional responsibility.
Difficulties with quality assurance
Training requirements
Employees need to understand:
the required standard
their responsibility for achieving it
how to identify or prevent problems.
This may require training.
AQA's 2025 mark scheme specifically identifies the higher training requirements of QA as a potential disadvantage relative to QC.
The chain is:
QA requires employees to take responsibility for quality
↓
employees require appropriate training
↓
training takes time and money
↓
operating costs may rise
↓
QA is only worthwhile if the improvement in quality justifies those costs
This can make QA less attractive where its expected additional quality improvement is small.
QA depends heavily on employees
Quality assurance relies on employees completing their responsibilities effectively.
AQA's 2025 mark scheme notes that expecting every worker to avoid mistakes may be unrealistic.
Therefore:
quality responsibility spread across workforce
↓
one or more employees make mistakes
↓
a defect may not be prevented
↓
without a separate final inspection, faulty output may potentially leave the business
This is a key argument for why QC may remain more suitable in some circumstances.
Changing employee responsibilities
Introducing QA may involve a significant change in how employees work.
Employees who previously regarded quality checking as another person's role now need to take direct responsibility.
The value of QA can therefore depend on:
employee skills
management
business culture.
These factors are specifically recognised in AQA's 2025 mark scheme as relevant when evaluating whether QA or QC is preferable.
Quality control versus quality assurance
The difference between the methods must be learned precisely.
Quality control (QC) | Quality assurance (QA) |
Focuses strongly on inspecting or checking output | Builds responsibility for quality into the operational process |
Aims to identify faulty output before it reaches customers | Aims to prevent faults occurring |
Inspection may be undertaken separately from production | Quality becomes part of employees' responsibilities |
Faults may be detected after resources have already been used | Right-first-time approach aims to reduce defects and waste |
May require less workforce training | May require greater employee training |
Provides a final inspection safeguard | Does not rely primarily on separate final inspection |
Employees may regard quality as the inspector's responsibility | Employees have direct responsibility for achieving quality |
⚠️ Exam warning: Do not reverse the definitions.
The 2025 examiner report identified confusion between quality assurance and quality control as a significant problem for some students.
A simple way to remember the difference
Think:
Quality control = detect
Quality assurance = prevent
Quality control focuses on finding problems in output.
Quality assurance focuses on building processes and employee responsibility around avoiding problems in the first place.
This is a useful memory aid, but your exam explanation should still show the full distinction.
Quality control and wastage
Suppose a manufacturer produces 10,000 units and inspection identifies 500 as faulty.
Those 500 units have already used:
materials
labour
operational time.
Even if they are prevented from reaching customers, there is still an efficiency consequence.
If the business could prevent more defects occurring:
less faulty output produced
↓
less waste
↓
lower total cost for the level of usable output
↓
potentially lower unit cost
This is why the right-first-time approach can provide an important cost advantage.
Quality assurance and profit
AQA's 2025 assessment required students to analyse how QA and QC could affect profit. The mark scheme recognised several routes through which improved quality may contribute to higher profit, including:
increased perceived value and sales
scope for higher prices
lower wastage and unit costs.
For QA specifically:
right first time
↓
less wastage
↓
lower unit costs
↓
higher profit margin if selling price is maintained
Alternatively:
more consistent quality
↓
greater customer value
↓
potential increase in sales
↓
potential increase in profit
These are possible outcomes rather than guarantees.
Quality control and profit
Quality control can also contribute positively to profit.
For example:
inspection prevents defective product reaching customer
↓
fewer customers receive faulty goods
↓
business reduces consequences of poor quality
↓
customer demand may be better protected
↓
profit may be supported
QC may also be more cost-effective than QA if achieving full employee responsibility for quality would require extensive training for only a small improvement in quality.
Therefore, it is wrong to assume QA automatically creates higher profit than QC.
Choosing the most suitable approach
The best quality method depends on the business context.
AQA's 2025 mark scheme specifically identifies relevant factors including:
business culture
leadership style
workforce skills
nature of the product
importance of quality to customers
level of competition.
These provide a useful framework for evaluation.
Workforce skills
Quality assurance depends heavily on employees being capable of taking responsibility for quality.
If employees are highly skilled and well trained:
employees understand the required standard
↓
workers can prevent and identify problems during their own activities
↓
QA may operate effectively
By contrast, where employees have limited skills or experience, a separate inspection process may provide a valuable safeguard.
Therefore, QC may sometimes be more suitable even though QA has potential waste-reduction advantages.
Training costs
Managers should compare:
cost of training employees for QA
with:
expected savings and improvements from preventing faults.
Suppose QA requires significant training but the current QC system already produces very few defects.
The additional improvement may be too small to justify the cost.
AQA's 2025 mark scheme explicitly identifies this possibility.
The correct conclusion is therefore not:
QA is always cheaper.
It is:
QA may be more cost-effective where preventing defects creates sufficiently large savings to justify the additional training and organisational requirements.
Nature of the product
The type of output can affect the suitability of the quality method.
A business needs to consider:
how serious a defect would be
how easily quality can be checked
whether defects can be prevented reliably during the process.
Where preventing faulty output from leaving the business is particularly important, the final-check feature of quality control may be valuable.
Where large amounts of waste result from discovering faults only after production, quality assurance may be more attractive because its right-first-time approach aims to stop defects occurring.
The relevant argument depends on the context supplied in the question.
Importance of quality to customers
Where customers place great importance on consistent quality, a business has a stronger incentive to ensure that its chosen method works effectively.
AQA's 2025 mark scheme specifically identifies the importance of quality to the customer as a factor when choosing between QA and QC.
The chain might be:
customers place high value on quality
↓
poor quality could significantly affect demand
↓
business needs a highly effective quality system
↓
choice between QA and QC should depend on which approach most reliably achieves the required standard
This leads directly into the value and difficulties of improving quality [The value and difficulties of improving quality].
Competition
The level and nature of competition may make quality improvement more important.
If customers can easily move to competing businesses:
poor-quality output
↓
customers have alternatives
↓
business risks losing sales to competitors
↓
effective quality management becomes particularly important
However, managers still need to decide which quality method provides the best balance of:
quality improvement
cost
reliability.
Competition does not automatically make QA preferable to QC.
Business culture
AQA identifies business culture as another relevant factor when comparing the approaches.
QA requires employees throughout the operation to accept responsibility for quality.
If the existing culture supports:
responsibility
employee involvement
attention to quality,
QA may fit the organisation well.
If employees expect quality to be someone else's responsibility, introducing QA may require a more significant change.
This may make implementation slower or more difficult.
Leadership and management
The choice can also depend on leadership.
Managers implementing QA need employees to understand and accept their quality responsibilities.
The approach may therefore depend on how successfully managers:
communicate expectations
provide training
encourage responsibility.
Again, the specification does not require a separate quality-management model here. Apply the leadership knowledge already studied where it genuinely helps explain the context.
Quality assurance and employee motivation
The potential motivational benefit of QA is important, but it should not be overstated.
The stronger argument is:
greater employee responsibility
↓
may increase motivation
↓
employees may take more ownership of their work
↓
quality may become more consistent
The word may matters.
Some employees might instead view increased responsibility as an additional demand, especially if training or support is inadequate.
Context determines the effect.
Quality control may be suitable for some businesses
Students sometimes treat QC as an outdated or automatically inferior method.
That is incorrect.
AQA's 2025 mark scheme gives clear reasons why QC may outperform QA in some situations:
it may require less training
relying on every worker to avoid mistakes may be unrealistic
QC provides an inspection stage specifically intended to prevent faulty products leaving the business.
A strong answer therefore treats both methods as potentially valid.
Quality assurance may be suitable for some businesses
Similarly, QA can provide important advantages:
greater worker responsibility
possible motivational benefits
right-first-time production
lower wastage
potentially greater consistency
lower need for a separate inspection team.
The question is not whether QA is "better" in general.
The question is whether its advantages are more important in the particular business context.
Quality methods and unit costs
Both approaches create different cost implications.
QC may create costs through:
inspection
separate quality-checking employees
defects being discovered after resources have already been used.
QA may create costs through:
training
changing employee responsibilities
implementing the quality system.
But QA may also reduce:
defective output
waste
separate inspection costs.
The net effect depends on the relative size of these costs and savings.
Quality methods and competitiveness
Both QA and QC can contribute to competitiveness if they help the business supply the standard customers expect.
For example:
effective quality method
↓
fewer poor-quality products reach customers
↓
customer satisfaction is protected
↓
business maintains demand
↓
competitive position may strengthen
QA may add another route:
more consistent right-first-time quality
↓
less waste and potentially lower unit costs
↓
business can compete more effectively on cost as well as quality
However, if QA is expensive to implement, QC might provide a better balance for some businesses.
Quality and added value
Improving quality may increase the value customers perceive in a product.
The potential chain is:
improved quality
↓
customer perceives greater value
↓
added value may increase
↓
business may have greater scope to charge a higher price
↓
profit may increase
However, whether customers actually value the improvement is important.
AQA's 2025 mark scheme notes that quality improvements may be unnecessary if customers are not willing to pay a higher price for them.
This is an important evaluation point.
Is QA always better than QC?
No.
AQA's own 2025 mark scheme states that both approaches are geared towards improving quality and that there is no single definitive conclusion about which produces the better outcome.
QA may be preferable when:
waste from defects is significant
employees are sufficiently skilled
training can be provided effectively
employee responsibility fits the business culture
consistent quality is particularly important.
QC may be preferable when:
a final inspection safeguard is particularly important
workforce training for QA would be expensive
expecting every worker to prevent all mistakes is unrealistic
inspection provides a cost-effective way of protecting customers.
A business may therefore choose the method that best fits its circumstances.
Building an exam chain for quality control
A weak answer:
QC checks products so quality is better.
A stronger response:
finished output is inspected
↓
faulty goods are identified
↓
defective goods are prevented from reaching customers
↓
fewer customers experience poor-quality products
↓
customer satisfaction and demand may be protected
↓
profit may be higher than if defective goods were sold
This explains why inspection matters.
Building an exam chain for a QC disadvantage
QC focuses on detecting defects
↓
fault may only be discovered after the product has been made
↓
materials and labour have already been used
↓
faulty output may become waste
↓
unit costs increase
↓
profit margins may fall
This shows why prevention can sometimes be preferable.
Building an exam chain for quality assurance
employees take responsibility for quality throughout production
↓
right-first-time approach prevents more defects
↓
less output is wasted
↓
unit costs may fall
↓
business can achieve higher margins or compete more strongly on price
This creates a clear connection between QA and business performance.
Building an exam counterargument
QA requires all employees to take responsibility for quality
↓
significant training may be required
↓
training creates time and financial costs
↓
if the improvement in quality is only small
↓
the cost of QA may outweigh its additional benefits
↓
QC may be more cost-effective
This gives a balanced basis for evaluation.
A method for choosing between QA and QC
When given a business context, ask:
1. How important is quality?
Would defects have a significant effect on customers and competitiveness?
2. What is happening under the current system?
Are there:
many defects
high wastage
high inspection costs?
3. What is the workforce like?
Are employees:
skilled
experienced
capable of taking responsibility for quality?
4. What would QA require?
Consider:
training
greater responsibility
cultural change.
5. What would QC provide?
Consider:
inspection
final protection against faulty output
lower training requirements.
6. Which benefits matter most in this context?
The answer might depend on:
cost
consistency
customer expectations
competition
workforce characteristics.
This turns generic knowledge into contextual evaluation.

Hints from the Examiner Reports 💡
Examiner hint: Learn the distinction between QA and QC precisely. In the 2025 Paper 1 essay, a significant minority of students confused the two approaches, which meant arguments were attributed to the wrong method.
Examiner hint: A sound general understanding of quality cannot fully compensate for mixing up QA and QC. The 2025 mark scheme treats sustained confusion between the two as a major mis-categorisation.
Examiner hint: Move beyond a simple list of advantages and disadvantages. The 2025 examiner report found that weaker essays tended to give straightforward pros and cons, while stronger responses discussed how QA and QC affected the required business outcome in different contexts.
Examiner hint: Use the business context to choose between the approaches. Better 2025 responses applied quality arguments effectively rather than making a universal claim that one system was superior.
Examiner hint: Evaluation can depend on workforce skills, business culture, leadership, the nature of the product, the importance customers place on quality and competition. These are all factors recognised by the 2025 mark scheme when comparing QA and QC.
Common Mistakes ⚠️
Mistake: Reversing quality control and quality assurance
Why this is incorrect: QC focuses on inspection and identifying faulty output. QA builds responsibility for achieving quality into the operational process.
This confusion was specifically identified by AQA in 2025.
How to improve: Remember:
QC = detect
QA = prevent
Then develop the full definitions in your answer.
Mistake: Saying QA means checking every product at the end
Why this is incorrect: That describes the inspection focus associated with quality control.
How to improve: For QA, explain that responsibility for quality is built into employees' work and linked to a right-first-time approach.
Mistake: Saying QC prevents all waste
Why this is incorrect: QC may identify a fault only after resources have already been used producing the defective output.
How to improve: Distinguish between:
preventing faulty output reaching customers
preventing the fault occurring in the first place.
Mistake: Assuming QA is always cheaper
Why this is incorrect: QA may reduce waste and inspection costs, but it can require substantial employee training.
How to improve: Compare the costs of introducing QA with the value of the quality improvement it produces.
Mistake: Assuming QC is always inferior
Why this is incorrect: QC provides a specific inspection safeguard and may require less employee training.
AQA explicitly recognises situations where QC may be preferable.
How to improve: Judge each method using the circumstances of the business.
Mistake: Assuming every employee will respond positively to responsibility for quality
Why this is incorrect: QA depends on employees successfully taking responsibility and avoiding mistakes.
How to improve: Consider workforce:
skills
training
culture
management.
Mistake: Describing quality improvement without linking it to the question
Why this is incorrect: Explaining QA or QC alone does not provide developed analysis.
How to improve: Build towards the outcome required, for example:
quality method → fewer defects → lower waste → lower unit costs → higher profit.
Mistake: Assuming higher quality automatically increases profit
Why this is incorrect: Improving quality may create additional costs, and customers may not value the improvement sufficiently to justify them.
How to improve: Compare:
benefit from improved quality
with
cost of achieving the improvement.
Exam-Style Questions ✍️
Question 1
Which one of the following best describes quality assurance?
A. Inspecting final output and removing faulty products
B. Giving employees responsibility for achieving quality throughout the operational process
C. Increasing inventory to protect against shortages
D. Increasing productive capacity
[1 mark]
Answer: B.
Question 2
Explain one difference between quality control and quality assurance.
[3 marks]
Indicative answer:
Quality control focuses on inspecting output to identify products that fail to meet the required standard. Quality assurance instead builds responsibility for achieving quality into the operational process, aiming to prevent faults through a right-first-time approach.
Mark guidance:
Credit:
accurate understanding of QC
accurate understanding of QA
a clear distinction.
Question 3
Explain one possible advantage of quality control.
[4 marks]
Indicative answer:
Quality control allows a business to inspect output before it reaches customers. Faulty products can therefore be identified and prevented from being sold. This may reduce the number of customers receiving defective products and protect customer satisfaction.
Question 4
Explain one possible advantage of quality assurance.
[4 marks]
Indicative answer:
Quality assurance encourages employees to achieve the required standard correctly the first time. If fewer defective products are produced, wastage may fall. This could reduce unit costs and improve the business's operational efficiency.
Question 5
Precision Toys Ltd currently uses quality control. A team of employees checks completed products and rejects any that fail to meet the required standard.
Last year:
6% of completed products failed inspection
rejected products could not be sold
inspection-team costs were £180,000.
Managers are considering introducing quality assurance.
Analyse one possible benefit to Precision Toys Ltd of changing to quality assurance.
[9 marks]
Indicative content:
Currently 6% of completed products fail inspection.
Resources have already been used creating these products before faults are identified.
QA would give employees greater responsibility for achieving quality during production.
A right-first-time approach may prevent more defects.
Fewer rejected products could reduce wastage.
The business may also reduce its need for a separate inspection team costing £180,000.
Lower waste and inspection costs may reduce unit costs.
Profit margins could improve if selling prices remain unchanged.
Mark guidance:
Higher-level responses should use the contextual information and develop the chain from:
QA → prevention of defects → cost effect → business consequence.
Question 6
SkillCraft Ltd produces individually made products using highly skilled and experienced employees. Managers are considering replacing its quality-control inspection system with quality assurance.
Analyse why quality assurance may be particularly suitable for SkillCraft Ltd.
[9 marks]
Indicative content:
SkillCraft's employees are highly skilled and experienced.
QA requires employees to take responsibility for achieving quality.
Skilled employees may be more capable of identifying and preventing mistakes within their own work.
A right-first-time approach may therefore reduce defective output and waste.
Giving skilled employees additional responsibility could also increase motivation.
This may improve consistency and reduce reliance on separate inspection.
Mark guidance:
Higher-level responses should make the workforce characteristics central to the argument.
Question 7
BudgetParts Ltd employs a large number of recently recruited production employees. Staff training costs have risen sharply. Its current quality-control system identifies most defective products before they leave the factory.
Analyse one reason why BudgetParts Ltd might continue to use quality control rather than quality assurance.
[9 marks]
Indicative content:
Many employees are recently recruited.
QA would require employees to take responsibility for preventing faults.
This may require significant additional training.
Training costs are already rising.
The current QC system successfully identifies most defective products before they leave the factory.
The additional improvement from QA may therefore be relatively small compared with its training costs.
QC could consequently remain more cost-effective.
Credit other valid developed arguments.
Question 8
FreshHome Appliances Ltd wants to improve quality.
Its managers are considering two options.
Option A: Quality control
retain a specialist inspection team
annual inspection cost: £240,000
faulty products are identified before dispatch
approximately 4% of output currently fails inspection.
Option B: Quality assurance
all production employees become responsible for quality
initial employee training cost: £350,000
managers expect defective output to fall
the separate inspection team would no longer be required.
Customers have many competing brands to choose from and expect reliable products.
Assess which quality method is likely to be more suitable for FreshHome Appliances Ltd.
[16 marks]
Arguments supporting QA may include:
Currently 4% of output fails inspection, meaning resources have already been used creating defective products.
QA aims for right-first-time production.
Fewer defects could reduce wastage.
Quality may become more consistent because responsibility is built into employees' roles.
The £240,000 annual inspection cost could potentially be removed.
Reliable quality is particularly important because customers have many competing brands available.
Greater employee responsibility may improve motivation.
Arguments supporting QC may include:
QA requires £350,000 of initial training expenditure.
The success of QA depends on production employees reliably preventing mistakes.
QC currently ensures that faulty products are identified before dispatch.
A specialist inspection function therefore provides a final safeguard.
If QA creates only a small improvement on the existing 4% defect rate, the additional training cost may not be justified.
Customer expectations for reliability may make a final inspection particularly valuable.
Evaluation:
QA could be more suitable if the 4% failure rate creates substantial wastage and the trained workforce can successfully achieve right-first-time production. Eliminating the £240,000 annual inspection cost would also become increasingly significant over time.
However, QC may remain preferable if preventing faulty appliances from reaching customers requires a particularly reliable final check or if employees cannot achieve sufficiently consistent standards without inspectors.
A justified conclusion should therefore depend on how effectively training reduces defects compared with the current QC system, rather than assuming either method is universally superior.
Question 9
A business with a highly skilled workforce should focus on quality assurance rather than quality control.
To what extent do you agree?
[25 marks]
Indicative content:
Arguments supporting quality assurance:
Skilled employees may be capable of taking responsibility for quality.
QA encourages a right-first-time approach.
Fewer defects may reduce wastage and unit costs.
Greater responsibility may motivate employees.
Quality may become more consistent.
A separate inspection team may no longer be necessary.
Lower waste and inspection costs could improve profits.
Arguments supporting quality control instead:
Skilled employees can still make mistakes.
QC provides a specific safeguard preventing faulty output leaving the business.
QA may require additional training despite existing employee skills.
The financial benefit of QA may be small if the current defect rate is already low.
The nature of the product may make final inspection particularly important.
The best method depends on how much customers value quality and the consequences of defective output.
Evaluation:
A skilled workforce can make QA particularly attractive because employees may be well placed to accept responsibility for achieving quality and preventing defects.
However, workforce skill is only one factor. The decision should also consider:
training costs
current defect levels
the cost of inspection
the nature of the product
customer expectations
competition
business culture.
A strong judgement should therefore explain why the workforce characteristics matter in combination with the wider business context, rather than concluding that QA is automatically superior whenever employees are highly skilled.
