Matching supply to demand A-Level Business revision overview
AQA requires students to understand how to manage supply to match demand and the value of doing so.
The specification identifies three ways of matching supply to demand:
outsourcing
use of temporary and part-time employees
producing to order.
These methods help businesses adjust the resources or output they provide according to the amount customers want to buy.
This section forms part of AQA's wider topic of managing inventory and supply chains, so decisions should eventually be connected with inventory management [Inventory management], choosing suppliers [Choosing suppliers], supply-chain management [Supply-chain management] and outsourcing [Outsourcing].
What does matching supply with demand mean?
In this operational context:
demand is the amount of goods or services customers want
supply is the amount the business is able and willing to provide.
A business is matching supply with demand when its operational resources and output are broadly appropriate for the level of customer demand.
For example, if a business expects a temporary rise in customer demand, it may need:
more productive capacity
additional employees
extra output from another business.
If demand falls, maintaining the same level of resources may leave productive capacity unused.
📌 Important: This lesson is about operationally matching what a business provides with customer demand. It is not about drawing an economic supply-and-demand diagram.
Why matching supply and demand matters
If supply is significantly different from demand, operational problems can arise.
There are two broad situations:
supply is too low for demand
supply is too high for demand.
Both may damage business performance.
When demand is greater than supply
Suppose a manufacturer can currently produce 5,000 units per week but customers want 6,500.
Demand exceeds the amount the business can currently supply by:
6,500−5,000=1,500 units
6,500-5,000=1,500\text{ units}
The business may be unable to satisfy all potential customers.
Possible consequences include:
lost sales
longer waiting times
dissatisfied customers
customers buying from competitors
pressure on existing employees and productive resources.
The business therefore needs to decide whether and how to increase its ability to supply customers.
AQA has directly assessed this principle. In the 2023 Paper 1, outsourcing more production to other manufacturers was identified as the action that would improve a manufacturer's ability to respond to changes in consumer demand.
When supply is greater than demand
A business may also have more resources or capacity than customer demand requires.
Suppose:
maximum capacity = 100,000 units
customer demand requires output of only 55,000 units.
A significant proportion of the business's productive capacity is unused.
This can create:
spare capacity
underused employees or assets
fixed costs associated with resources that are not fully used
unnecessary inventory if goods are produced without sufficient demand.
This connects directly with capacity and capacity utilisation [Capacity and capacity utilisation].
Matching supply to demand and efficiency
A business may improve efficiency by removing resources that are no longer required.
AQA has previously assessed this in a service context. In the 2021 Paper 2, branch closures by large banks were described as a way of matching supply with demand as customers increasingly used online banking. The mark scheme recognised that underused branches tied up fixed assets and employed staff, while closing surplus capacity could reduce fixed costs and improve efficiency.
The chain is:
demand for existing capacity falls
↓
some resources become underused
↓
business reduces surplus capacity
↓
fixed costs may fall
↓
efficiency may improve
↓
profit may increase
However, the same AQA assessment also recognised a possible disadvantage. Closing branches could worsen customer service, cause dissatisfaction and lead some customers to switch businesses.
Matching supply to demand therefore involves trade-offs, not simply cutting resources.
Matching supply to demand and flexibility
Flexibility is one of the operational objectives studied in operational objectives [Operational objectives].
A flexible business may be better able to change its supply when demand changes.
For example:
demand suddenly increases
↓
business can increase resources or output
↓
additional customers can be served
↓
fewer sales are lost
↓
competitiveness may improve
Several of the methods in this lesson provide flexibility without requiring the business to permanently increase its own resources.
Demand may change
Businesses need methods of matching supply with demand because demand does not always remain constant.
Demand may:
rise
fall
fluctuate during particular periods
be difficult to predict.
The business therefore needs to decide whether a change in demand is likely to be:
temporary
longer lasting.
This can strongly influence the most appropriate response.
For example, permanently increasing internal resources may be less attractive if managers believe the increase in demand will last only a short time.
The three AQA methods
The three methods required by the specification can be viewed as different ways of increasing flexibility.
Method | What the business changes | Main idea |
Outsourcing | Uses another business to provide some activity or output | External capacity can help meet demand |
Temporary and part-time employees | Adjusts the amount of labour available | Employee resources can be matched more closely with demand |
Producing to order | Produces in response to customer orders | Output is more closely linked to actual demand |
AQA explicitly requires all three approaches.
Outsourcing
Outsourcing occurs when a business uses another organisation to carry out an activity that could otherwise be carried out internally.
For matching supply with demand, the key use is obtaining additional output or operational capability from an external business.
For example, a manufacturer whose own operation cannot supply enough products may outsource some production to another manufacturer.
AQA directly tested this relationship in 2023, identifying outsourcing more production as a way for a manufacturer to improve its response to changes in consumer demand.
Outsourcing and additional capacity
Suppose a business has:
internal maximum output = 20,000 units
customer demand = 25,000 units.
The business is 5,000 units short of the output required.
If another manufacturer can produce those 5,000 units:
demand exceeds internal capacity
↓
some production is outsourced
↓
external business provides additional output
↓
total supply increases
↓
more customer demand can be satisfied
This allows the business to respond without immediately expanding its own permanent productive capacity.
Outsourcing when internal capacity utilisation is high
Outsourcing may be particularly attractive where a business is already using a large proportion of its internal capacity.
AQA has tested students on the relationship between:
capacity utilisation
predictability of demand
outsourcing.
If internal capacity is already heavily used, the business has limited spare capability to increase output itself.
Outsourcing can provide another source of supply.
This links back to capacity and capacity utilisation [Capacity and capacity utilisation].
Outsourcing and uncertain demand
Outsourcing can be useful where managers are uncertain whether increased demand will continue.
Consider a business experiencing a short-term rise in orders.
It has two possible responses:
Option 1: invest in permanent additional internal capacity.
Option 2: outsource the extra production.
Outsourcing may provide greater flexibility because:
temporary demand increase
↓
business outsources additional output
↓
demand can be met without permanently expanding internal capacity
↓
if demand later falls, the business is not left with the same amount of additional internal capacity
This can reduce the risk associated with committing permanently to higher supply.
Outsourcing and responsiveness
AQA's 2023 objective test provides a useful exam principle:
Outsourcing can improve a manufacturer's ability to respond to changing consumer demand.
The reasoning is:
demand increases
↓
internal resources alone are insufficient
↓
external producer supplies additional output
↓
business can respond more quickly than if it first had to expand its own permanent operation
↓
customer demand is more likely to be satisfied
This can support the operational objectives of:
flexibility
speed of response.
Potential difficulty of outsourcing
Using another business can solve a capacity problem, but the business becomes dependent on that external organisation for some of its supply.
This creates potential issues around:
quality
reliability
cost.
These are deliberately explored in more depth later in outsourcing [Outsourcing] and choosing suppliers [Choosing suppliers].
For this lesson, the important point is:
outsourcing increases available supply
but:
the business must rely on an external organisation to deliver what is required.
If the external organisation cannot provide the required output at the required time, the original mismatch between supply and demand may remain.
Outsourcing may affect costs
Outsourcing is not automatically cheaper or more expensive.
A business needs to compare:
the cost of buying the activity externally
the cost of providing additional capacity itself.
Suppose outsourcing allows a business to respond to a temporary increase in demand without purchasing additional long-term productive assets.
This may be attractive because the business avoids committing resources to capacity that could later become unnecessary.
However, if the outsourced provider charges a high price, the cost per unit may rise.
The decision should therefore be judged in context.
Outsourcing as a temporary or continuing response
The value of outsourcing may depend on how long the demand change is expected to last.
Temporary demand increase
Outsourcing may provide useful flexibility without a permanent expansion.
Sustained demand increase
If demand is expected to remain high for many years, permanently increasing internal capacity may eventually become more attractive.
The correct decision therefore depends partly on the predictability and expected duration of demand.
Temporary employees
A temporary employee works for the business for a limited period rather than necessarily being required as a permanent addition to its workforce.
Temporary employees allow a business to increase its labour supply when it needs additional employees.
This is one of the three ways of matching supply with demand explicitly identified by AQA.
Using temporary employees when demand rises
Suppose a business normally requires 100 employees but expects unusually high demand for two months.
Recruiting permanent employees could leave the business with more labour than it requires when demand returns to normal.
Temporary employees provide an alternative:
short-term demand rises
↓
additional temporary employees recruited
↓
labour available increases
↓
business can provide more output or serve more customers
↓
when temporary demand ends, the business does not necessarily retain the same permanent labour commitment
This can make the workforce more responsive to changes in demand.
Temporary employees and flexibility
The main operational advantage is flexibility.
A business can alter the size of its workforce more closely in response to changing demand.
For example:
demand increases temporarily
↓
temporary employees added
↓
supply increases
then:
demand falls
↓
temporary employment period ends
↓
labour supply falls again
This may be more suitable than changing permanent employee numbers whenever demand fluctuates.
Temporary employees and costs
Using temporary employees may allow a business to avoid permanently employing workers who are not needed throughout the year.
For example:
temporary peak in demand
↓
temporary workers employed only when additional labour is required
↓
business avoids maintaining the same enlarged workforce during periods of lower demand
↓
employee costs may be matched more closely to operational needs
However, cost alone should not determine the decision.
The business also needs employees who can perform the required activities effectively.
Difficulties associated with temporary employees
Temporary employees may create difficulties if:
the work requires significant training
employees need detailed business-specific knowledge
the quality of output depends heavily on experience.
For example:
temporary worker recruited for short period
↓
worker requires training before becoming effective
↓
time and resources are spent on training
↓
employee may leave once temporary need ends
↓
benefit of temporary employment may be reduced
The significance depends on the type of work.
A temporary employee may be more suitable where the work can be learned relatively quickly than where it requires extensive specialist development.
Part-time employees
A part-time employee works fewer hours than a comparable full-time employee.
AQA specifically includes part-time employees as a way of matching supply to demand.
The value comes from allowing managers to schedule employee hours more closely around the periods when customers actually require the business's output or service.
Part-time employees and changing demand during the day
Imagine a restaurant where customer demand is:
low during the afternoon
very high during the evening.
Employing the same number of full-time employees throughout the entire day may result in surplus labour during quiet periods.
Part-time employees can be scheduled for the busy period.
The chain is:
demand rises at particular times
↓
part-time employees work during those periods
↓
labour supply rises when customer demand is high
↓
business can serve more customers
↓
labour resources are more closely matched to demand
This can improve operational efficiency.
Part-time employees and seasonal or weekly patterns
Part-time employees can also be valuable where demand varies predictably.
For example:
particular days may be busier
certain times of day may require more staff
some periods of the year may have higher demand.
The business can schedule more employee hours when required rather than maintaining the same labour supply continuously.
Advantages of part-time employees for matching demand
Part-time working may allow the business to:
increase employee availability during busy periods
reduce surplus labour during quieter periods
make labour supply more flexible
respond to predictable fluctuations in demand.
The key analytical chain is:
demand varies predictably
↓
employee hours are scheduled around busy periods
↓
labour is available when customers need it
↓
less labour is unused during quiet periods
↓
resources may be used more efficiently
Difficulties associated with part-time employees
Part-time employment is not automatically suitable for every role.
Possible issues include whether:
enough suitable employees are available at the required times
the role can be divided effectively into shorter working periods
customers require continuity from the same employee
extensive training is required.
The business should therefore compare the flexibility gained with how well part-time working suits the operational task.
Temporary versus part-time employees
These terms are not interchangeable.
Temporary employees | Part-time employees |
Employed for a limited period or temporary need | Work fewer hours than full-time employees |
Useful when the business needs additional labour for a period | Useful when the business needs labour for particular hours or periods |
Can help respond to short-term changes in demand | Can help schedule labour around recurring patterns of demand |
Main distinction concerns duration of employment | Main distinction concerns hours worked |
A part-time employee does not have to be temporary.
Likewise, a temporary employee could be needed for a significant number of hours during the limited period in which they are employed.
📌 Exam point: Use the correct method for the demand problem described in the case.
Producing to order
Producing to order means producing goods or services in response to customer orders rather than creating the same amount of finished output in advance without knowing whether it will be sold.
It is the third method of matching supply to demand specifically required by AQA.
The basic process is:
customer places an order
business knows there is demand
production takes place in response
output is supplied to the customer.
Supply is therefore directly linked to actual customer demand.
Producing to order reduces the risk of excess finished output
Suppose a furniture business produces 1,000 tables without confirmed customer orders, but only 700 are demanded.
The business may be left with 300 finished units that have not been sold.
Producing to order reduces this risk because production occurs in response to actual orders.
The chain is:
customer order received
↓
business produces required output
↓
production corresponds more closely to actual demand
↓
less risk of unsold finished output
↓
fewer resources are tied up in finished goods
This makes producing to order particularly relevant when holding unnecessary finished inventory is costly.
Producing to order and inventory
AQA's 2024 Paper 2 mark scheme identified producing to order as a way a business could improve cash flow by having less cash tied up in finished goods or inventory.
The reasoning is:
produce only when an order exists
↓
less finished output is produced in advance
↓
less cash tied up in finished inventory
↓
cash-flow position may improve
This creates an important link with finance without moving beyond the operational purpose of the method.
The management of inventory itself is examined next in inventory management [Inventory management].
Producing to order and waste
Producing to order may also reduce unnecessary output.
If the business produces goods before it knows whether customers want them, there is a risk that some will remain unsold.
If these goods cannot later be sold successfully, resources used creating them have been wasted.
Producing in response to actual orders can therefore:
reduce unnecessary production
↓
reduce surplus finished inventory
↓
reduce the risk of waste
↓
improve operational efficiency
The significance will depend on the type of product.
Producing to order and customisation
Producing after an order is received may also allow the business to provide output according to the customer's requirements.
However, the specification focus here is matching supply with demand.
In an examination answer, the central point should therefore be:
production is triggered by actual demand, reducing the risk that supply significantly exceeds demand.
Difficulty of producing to order: customers may need to wait
If production begins only once an order has been received, the product may not be immediately available.
The chain is:
customer places order
↓
production begins
↓
time is required to provide the output
↓
customer waits
↓
some customers may prefer a competitor offering immediate availability
This creates a trade-off between:
reducing unnecessary output
speed of response.
Whether this matters depends on customer expectations.
Producing to order and capacity
Producing to order does not eliminate the need for capacity.
If customer orders exceed what the business can produce:
orders rise sharply
↓
production required exceeds internal capacity
↓
waiting times may grow
↓
customers may become dissatisfied
The business may therefore need to combine producing to order with another method, such as outsourcing or additional employees.
This illustrates why different approaches can complement each other.
Producing to order versus producing before orders are received
Producing to order | Producing in advance |
Production responds to confirmed demand | Output is available before specific customer orders |
Lower risk of excess finished goods | Greater risk of unsold finished output |
Less cash may be tied up in finished inventory | More finished inventory may need financing |
Customers may have to wait for production | Products may be available immediately |
Useful where demand is uncertain | Can be useful where demand is predictable and speed matters |
The most suitable approach depends on the context.
Comparing the three methods
Factor | Outsourcing | Temporary/part-time employees | Producing to order |
Main purpose | Obtain additional external supply | Adjust labour resources | Link production directly to orders |
Useful when demand rises | Yes, external capacity can increase supply | Yes, more labour can increase supply | Production responds to confirmed orders |
Avoids permanent capacity expansion | Potentially | Temporary employees can avoid permanent workforce expansion | Does not necessarily require capacity expansion |
Key benefit | Flexibility through external provider | Flexible workforce | Reduced risk of excess finished output |
Main issue | Dependence on external organisation | Workforce suitability and training | Customer waiting time |
Particularly relevant when | Internal capacity is insufficient | Demand varies by time or period | Producing unnecessary finished goods would be costly |
Do not memorise the table as a rule. Use the circumstances given in the question.
Which method is best when demand rises unexpectedly?
If the increase is unexpected and immediate, managers need to consider how quickly additional supply can be created.
Outsourcing
May be valuable if an external business already has the capacity to provide additional output.
Temporary employees
May be valuable if additional workers can be recruited and become productive quickly.
Part-time employees
May help if existing or additional part-time labour can cover predictable busy periods.
Producing to order
Ensures production is linked to actual orders, but does not itself solve insufficient capacity if the number of orders exceeds productive capability.
The best option therefore depends on the nature of the operational constraint.
Which method is best for seasonal demand?
Suppose a business has a predictable annual peak.
Maintaining enough permanent resources for the busiest weeks could leave substantial resources underused during the rest of the year.
Temporary employees may be especially useful:
predictable seasonal increase
↓
temporary workforce expanded
↓
business increases supply during peak
↓
temporary requirement ends as demand falls
↓
business avoids keeping the same enlarged permanent workforce all year
Outsourcing could provide a similar type of flexibility if the external provider can supply the additional output reliably.
Which method is best when demand varies during the day?
Part-time employees may be particularly appropriate.
For example:
customer demand peaks between 17:00 and 21:00
↓
part-time employees scheduled for these hours
↓
more labour available at peak demand
↓
fewer unnecessary employee hours during quieter periods
↓
better match between labour supply and customer demand
The method is suitable because the timing of the demand fluctuation is predictable.
Which method is best when demand is difficult to predict?
There is no single answer.
Producing to order can reduce the risk of producing goods customers never request.
Outsourcing may provide additional flexibility if orders unexpectedly exceed internal capacity.
Temporary employees may be useful if additional labour can be obtained quickly.
The most appropriate method depends on:
how quickly demand changes
how quickly the business must respond
the cost of the method
the available internal capacity
the skills required
customer expectations.
The importance of demand predictability
Demand predictability is particularly important when deciding how much internal capacity to maintain.
AQA has previously tested outsourcing using a combination of:
current capacity utilisation
predictability of demand.
If demand is highly predictable, managers may be more confident when deciding how much permanent supply to provide.
If demand is unpredictable, flexible approaches may become more valuable because the business avoids committing permanently to resources that may not always be needed.
Matching supply to demand and capacity utilisation
The capacity data studied in operational performance data [Operational performance data] can help managers identify mismatches.
High capacity utilisation
The business may have little spare capacity available if demand rises.
Managers could consider:
outsourcing
additional employee hours
temporary employees.
Low capacity utilisation
The business may already have substantial unused capacity.
Creating even more capacity through outsourcing may therefore be unnecessary.
Instead, managers need to understand why demand is below existing supply.
Matching supply does not always mean increasing supply
This is a crucial point.
Students sometimes think the topic is only about responding to increases in demand.
Matching can also involve reducing supply when demand falls.
The 2021 bank-branch case demonstrates this clearly.
Demand for physical branches declined as online banking increased. Closing underused branches could remove surplus capacity and reduce costs.
Therefore:
demand falls
↓
existing supply becomes excessive
↓
business reduces operational resources
↓
supply becomes more closely aligned with demand
This can increase efficiency.
But reducing supply can go too far
The same 2021 mark scheme recognised that closing branches might:
worsen customer service
make customers dissatisfied
lead customers to switch banks
damage reputation.
The chain is:
business reduces supply too aggressively
↓
customers can no longer obtain the service they require conveniently
↓
customer satisfaction falls
↓
some customers switch competitors
↓
revenue may fall
This demonstrates why managers cannot focus only on cost reduction.
Matching supply and operational objectives
Methods of matching supply to demand can support several objectives from operational objectives [Operational objectives].
Cost
Avoiding unnecessary permanent capacity or labour may reduce costs.
Speed of response
Additional outsourced output or flexible labour may help the business respond more quickly when demand rises.
Flexibility
Temporary labour and outsourcing can allow supply to change with demand.
Quality
A rapid increase in supply should not cause the required quality standard to be lost.
Added value
More efficient use of resources may contribute to increased added value.
Managers need to judge the trade-off between these objectives.
Matching supply and customer satisfaction
The purpose is not merely to achieve the lowest possible operating cost.
The business also needs sufficient supply to satisfy customers.
For example:
business reduces labour too far
↓
customer demand exceeds available service capacity
↓
waiting times increase
↓
customers become dissatisfied
↓
competitiveness may fall
A cost saving can therefore be outweighed by a revenue loss.
This was a key feature of AQA's bank-branch assessment, where cost savings from closing capacity had to be balanced against possible customer losses.
Matching supply and competitiveness
A business can become more competitive if it responds effectively to customer demand without maintaining excessive resources.
One route is:
supply closely matches demand
↓
resources are not unnecessarily underused
↓
unit costs may be controlled
↓
business can compete more effectively on price or maintain stronger margins
Another is:
sufficient flexible supply
↓
business responds when demand rises
↓
customers obtain products or services when wanted
↓
fewer sales are lost to competitors
↓
competitive position strengthens
The most important route depends on the market.
Matching supply and finance
Operational decisions can have financial consequences.
Producing to order may reduce cash tied up in finished inventory. AQA explicitly recognised this relationship in the 2024 mark scheme.
Similarly:
unnecessary permanent capacity may create ongoing costs
temporary labour can avoid maintaining the same enlarged workforce during quieter periods
outsourcing involves paying another business for its output.
This illustrates the interrelationship between operations and finance.
Matching supply and human resources
Using temporary and part-time employees is both an operations and a human-resource decision.
Operations managers may want flexible labour because demand varies.
However, the business also needs to consider whether employees have:
suitable skills
sufficient training
availability at the required times.
The method can only improve supply if the employees are able to provide the required output effectively.
Matching supply and inventory
Producing to order can reduce the amount of finished inventory held because goods are not produced in the same quantities before customer orders exist.
However, managers still need to decide how much inventory is required for operations.
The next lesson, inventory management [Inventory management], examines:
lead time
re-order levels
buffer inventory
re-order quantities
influences on inventory holdings.
Matching supply and inventory management are therefore closely connected, but they are not the same topic.
Matching supply and suppliers
Outsourcing means relying on another business for some output.
The reliability and effectiveness of that outside provider may therefore influence whether outsourcing succeeds.
AQA's assessment material on suppliers recognises that delays can interrupt production and have knock-on effects for customers.
This connects with choosing suppliers [Choosing suppliers].
For this lesson, the essential analytical point is:
external supply can increase flexibility
but:
dependence on an external business introduces another potential source of operational risk.
Combining methods
Businesses do not necessarily need to choose only one method.
For example, a manufacturer might:
produce its normal level of output internally
use temporary employees during predictable seasonal peaks
outsource additional production if customer orders rise beyond internal capacity
produce some products only after orders are received.
The combination used should depend on the business's particular demand pattern.
This is a useful evaluation point because business decisions rarely need to be treated as all-or-nothing choices.
Choosing between temporary labour and outsourcing
Suppose a manufacturer has enough machinery to produce extra output but not enough employees.
Temporary employees may be appropriate because the main shortage is labour.
By contrast, suppose:
employees are fully occupied
machinery is already close to maximum capacity.
Hiring more temporary employees may not solve the problem because there is insufficient productive capacity for them to use.
Outsourcing may be more valuable because another producer provides additional productive capability.
📌 Exam technique: Identify what resource is limiting supply.
Choosing between producing to order and holding output in advance
The business should consider:
how predictable demand is
how quickly customers require the product
the cost of holding finished inventory
the cost of producing unwanted goods.
Producing to order may be attractive when:
demand is uncertain
products are costly to hold
customers accept a waiting period.
Producing in advance may have advantages when:
demand is predictable
customers expect immediate availability.
A good answer does not state that one approach is always more efficient.
Short-term versus long-term changes in demand
This is one of the most useful evaluation tools for this topic.
Short-term increase
Flexible methods may be particularly valuable:
outsourcing
temporary employees
part-time employees where working patterns allow.
Long-term increase
If demand is expected to remain permanently higher, the business may eventually need to reconsider:
its own capacity
its permanent workforce.
A temporary solution used indefinitely may not necessarily provide the best long-term value.
The cost of flexibility
Flexible methods are valuable because they allow resources to change with demand.
But flexibility can create costs.
For example:
an outsourced provider must be paid
temporary employees may require training
part-time working must be organised effectively
producing to order may create customer waiting time.
Therefore:
greater flexibility
does not automatically mean:
lower cost.
Managers must compare the value of flexibility with its cost.
Matching supply to demand in manufacturing
A manufacturer may experience:
demand above internal capacity
Possible responses include:
outsourcing production
temporary employees where labour is the limiting resource
producing to order to avoid unnecessary finished output.
The appropriate method depends on whether the problem is:
insufficient capacity
insufficient labour
uncertain demand.
Matching supply to demand in services
The same principle applies to services.
A service business may need to adjust:
employees
premises
service capacity.
The bank-branch example shows that supply-demand matching is not confined to manufacturing. AQA recognised branch closures as a response where increasing use of internet banking had left parts of the physical branch network underused.
For service businesses, the resource being matched may be the ability to serve customers, rather than physical units of production.
Building an outsourcing exam chain
A weak answer:
Outsourcing helps a business meet demand.
A stronger response:
consumer demand rises above internal productive capacity
↓
business outsources some production to another manufacturer
↓
additional output becomes available without immediately expanding internal capacity
↓
more customer orders can be fulfilled
↓
fewer sales are lost to competitors
↓
competitiveness may improve
The chain explains why outsourcing matters.
Building a temporary employee exam chain
seasonal demand rises
↓
business recruits temporary employees
↓
more labour is available during the busy period
↓
business can increase supply
↓
more customers can be served
↓
when demand falls, the enlarged workforce does not have to remain permanent
This links the method directly to the pattern of demand.
Building a part-time employee exam chain
demand is concentrated in particular hours
↓
part-time employees are scheduled during those hours
↓
labour supply rises when customers are present
↓
fewer employee hours are unused during quiet periods
↓
operational efficiency may improve
The key is matching working time to customer demand.
Building a producing-to-order exam chain
business waits for a confirmed order
↓
production takes place in response to actual demand
↓
less finished output is produced without a customer
↓
less cash is tied up in finished goods
↓
cash flow may improve
This relationship is explicitly supported by AQA's 2024 Paper 2 mark scheme.
Building a counterargument for outsourcing
business outsources additional production
↓
supply rises
but:
business depends on the external producer
↓
external producer is late or cannot supply required output
↓
customer orders are still delayed
↓
expected flexibility is not achieved
This allows you to analyse why outsourcing's value depends on the external supplier.
Building a counterargument for temporary employees
temporary employees increase labour supply quickly
but:
employees require significant training
↓
time and resources are required before they become fully effective
↓
short-term productivity may be lower than expected
↓
the demand peak may end before the full benefit is achieved
The method is therefore less suitable where extensive training is essential.
Building a counterargument for producing to order
producing to order reduces excess finished inventory
but:
production begins after order is received
↓
customers may have to wait
↓
customers who value immediate availability may choose a competitor
↓
sales may be lost
The correct method therefore depends partly on customer expectations.
Assessing the best method of matching supply with demand
When evaluating the alternatives, consider the following questions.
How predictable is demand?
Predictable fluctuations may make workforce scheduling easier.
Unpredictable changes may increase the value of flexible external supply.
Is the change temporary or permanent?
Temporary approaches are more attractive when the demand increase is unlikely to last.
What is current capacity utilisation?
If the business has significant spare internal capacity, outsourcing may be unnecessary.
If internal capacity is already heavily used, external supply may be more valuable.
What resource is in short supply?
Is the constraint:
labour
productive capacity
inventory?
The solution should address the actual problem.
How quickly must the business respond?
If customers expect immediate service, producing to order may be less suitable.
How important are quality and reliability?
Additional supply is not useful if it fails to meet the required standard.
What does each option cost?
The value of greater flexibility must be compared with the cost of achieving it.
A method for tackling matching-supply questions
Step 1: Identify the demand problem
Is demand:
rising
falling
seasonal
unpredictable
concentrated at particular times?

Common Mistakes ⚠️
Mistake: Treating this as an economics supply-and-demand topic
Why this is incorrect: AQA places this content within operational management. The issue is how the business adjusts its resources and output to customer demand.
How to improve: Think:
Does the business have the right amount of operational supply for the demand it faces?
Do not draw supply-and-demand curves unless another part of a question specifically requires them.
Mistake: Assuming matching supply to demand always means increasing supply
Why this is incorrect: Demand can fall as well as rise.
A business may need to reduce surplus capacity or other resources when demand falls.
How to improve: Always identify whether the case shows:
excess demand
excess supply.
AQA's bank case demonstrates how reducing underused capacity can also be a form of matching supply with demand.
Mistake: Assuming high capacity utilisation means outsourcing is always necessary
Why this is incorrect: The decision also depends on whether demand is expected to rise and how long the increase will last.
How to improve: Combine:
current capacity
demand pattern
predictability of demand.
Mistake: Confusing temporary employees with part-time employees
Why this is incorrect: Temporary employment concerns the limited duration of the employment need. Part-time employment concerns the number of hours worked.
How to improve: Remember:
temporary = how long
part-time = how many hours.
Mistake: Assuming temporary employees are always cheaper
Why this is incorrect: The business may face training or other costs, and the employees must still perform the required work effectively.
How to improve: Analyse the operational benefit first:
Does temporary labour allow the business to increase supply during a temporary demand peak?
Then consider the cost and suitability.
Mistake: Assuming outsourcing increases the business's own capacity
Why this is incorrect: Outsourcing provides supply from an external business. The original firm's own internal maximum capacity does not necessarily increase.
How to improve: Use precise language:
Outsourcing can increase the total output available to satisfy customers by using external productive capacity.
Mistake: Assuming outsourcing is only about cutting costs
Why this is incorrect: AQA has directly assessed outsourcing as a way of responding to changes in consumer demand.
How to improve: In this lesson, focus first on:
outsourcing → additional/flexible supply → improved response to demand.
Cost can then be considered as part of evaluation.
Mistake: Saying producing to order means the business has no inventory
Why this is incorrect: Producing to order refers to the timing of production relative to customer orders. It does not mean that every type of inventory disappears.
How to improve: Say:
Producing to order reduces the need to produce the same level of finished output in advance of actual customer demand.
Mistake: Ignoring the waiting time created by producing to order
Why this is incorrect: If production starts after an order is placed, customers may have to wait.
How to improve: Balance:
less risk of excess finished output
against:
potentially slower customer response.
Mistake: Choosing a method without identifying the cause of the mismatch
Why this is incorrect: Different methods solve different problems.
Hiring temporary employees does not necessarily solve a shortage of machinery capacity.
How to improve: First identify whether the limiting factor is:
labour
capacity
timing
uncertainty over actual orders.
Then choose the method.
Exam-Style Questions ✍️
Question 1
Which one of the following is specifically identified by AQA as a way of matching supply to demand?
A. Market mapping
B. Outsourcing
C. Share capital
D. Quality control
[1 mark]
Answer: B. Outsourcing.
Question 2
Explain what is meant by producing to order.
[2 marks]
Indicative answer:
Producing to order means that a business produces output in response to customer orders rather than producing the same quantity of finished goods in advance of confirmed demand.
Mark guidance:
1 mark for recognising that production responds to orders.
1 mark for distinguishing it from producing finished output in advance.
Question 3
A restaurant is quiet during the afternoon but extremely busy between 18:00 and 22:00.
Explain one reason why the restaurant may use part-time employees.
[4 marks]
Indicative answer:
Part-time employees could be scheduled to work during the busy evening period. This increases the amount of labour available when customer demand is high without requiring the restaurant to maintain the same number of employee hours during its quieter afternoon period. Labour supply may therefore be more closely matched with demand.
Question 4
A manufacturer expects a major increase in orders for three months. Managers are uncertain whether the increase will continue after this period.
Explain one reason why the manufacturer may use temporary employees.
[4 marks]
Indicative answer:
Temporary employees would increase the amount of labour available during the three-month increase in demand. This may allow the manufacturer to produce more output without permanently increasing the workforce when managers do not know whether the additional demand will continue.
Question 5
PeakCycles Ltd manufactures bicycles.
Its factory is currently close to maximum capacity. Customer orders have risen sharply, but managers believe the increase may last for only six months.
Analyse one reason why PeakCycles Ltd might outsource some production.
[9 marks]
Indicative content:
Internal capacity is already heavily used.
PeakCycles therefore has limited ability to increase output internally.
Outsourcing would allow another manufacturer to provide some of the additional bicycles.
Total supply available to PeakCycles' customers could increase.
This may allow more orders to be fulfilled and reduce lost sales.
The demand increase may last only six months.
Outsourcing may therefore provide flexibility without permanently expanding PeakCycles' internal capacity.
If demand later falls, the business may avoid being left with substantial unused additional internal resources.
Mark guidance:
Higher-level answers should develop:
capacity constraint → outsourcing → supply response → customer/business consequence.
Question 6
CustomDesk Ltd makes desks to individual customer orders.
Managers are considering changing to producing large quantities before customer orders are received.
Analyse one benefit to CustomDesk Ltd of continuing to produce to order.
[9 marks]
Indicative content:
Production begins in response to actual customer orders.
CustomDesk therefore has clearer evidence that demand exists before a finished desk is produced.
This reduces the risk of producing desks that remain unsold.
Less cash may be tied up in finished inventory.
Operational resources may be used more closely in response to actual demand.
This could improve cash flow and reduce the risk of waste.
The benefit may be particularly important if customer requirements differ significantly.
A strong answer should remain focused on matching supply with actual demand.
Question 7
CityGym Ltd experiences the following weekly customer demand:
Time | Customer demand |
Monday to Friday, 09:00 to 16:00 | Low |
Monday to Friday, 17:00 to 21:00 | Very high |
Saturday and Sunday | High |
Managers are considering employing more permanent full-time employees or increasing the number of part-time employees.
Analyse why part-time employees may be the better method of matching supply with demand.
[9 marks]
Indicative content:
Demand is concentrated in the evenings and weekends rather than being equally high throughout the week.
Part-time employees could be scheduled specifically during these high-demand periods.
Labour supply would therefore increase when more customers require the gym's services.
Fewer employee hours would be required during low-demand weekday periods.
This could reduce underused labour and improve efficiency.
Employing additional full-time employees might leave labour supply greater than demand during quiet periods.
Evaluation within analysis:
The value depends on whether suitable part-time employees are available and whether the work can be organised effectively around shorter working periods.
Question 8
OakFurniture Ltd produces household furniture.
Demand is difficult to predict. The business currently produces large quantities before receiving customer orders.
Managers are considering moving towards producing to order.
Last year:
average finished inventory was valued at £2.4 million
some finished furniture remained unsold for long periods
customers currently expect many products to be available quickly
competitors offer rapid delivery.
Assess whether OakFurniture Ltd should move towards producing to order.
[16 marks]
Arguments supporting producing to order may include:
Demand is difficult to predict, increasing the risk that production does not match what customers actually want.
Producing in response to orders would link supply more closely to confirmed demand.
Average finished inventory is currently valued at £2.4 million.
Producing to order may reduce the amount of cash tied up in finished goods.
It may reduce the amount of unwanted finished furniture remaining unsold.
This could improve operational efficiency and cash flow.
Arguments against may include:
Customers currently expect products to be available quickly.
Producing only after an order is placed may increase waiting times.
Competitors already offer rapid delivery.
Longer waiting times could cause some customers to choose competitors.
Producing to order does not solve a capacity problem if the business receives more orders than it can produce.
Evaluation:
Producing to order appears valuable because OakFurniture faces unpredictable demand and currently has £2.4 million tied up in finished inventory. Linking production more closely to actual orders could therefore reduce the risk of excess supply.
However, the most important limitation is customer response time. If customers are unwilling to wait and competing furniture businesses can supply quickly, a complete move to producing to order could weaken competitiveness.
A justified conclusion could therefore be that OakFurniture should increase its use of producing to order where the benefit of lower finished inventory outweighs the importance customers place on immediate availability.
Question 9
WaveWear Ltd sells seasonal clothing.
Demand increases sharply for three months each year. During this period, its existing employees and productive capacity cannot provide enough output.
Managers are considering two approaches:
Option A: Recruit temporary employees and increase internal production.
Option B: Outsource some production to another manufacturer.
The outsourced manufacturer can begin production immediately but charges a higher cost per unit. Temporary employees would cost less per unit once trained, but would require two weeks of training.
Assess which approach WaveWear Ltd should use to match supply with demand.
[16 marks]
Arguments supporting temporary employees may include:
The demand peak lasts three months, so a temporary workforce matches the limited duration of additional demand.
Temporary employees may allow WaveWear to increase internal output without permanently increasing employee numbers.
Their cost per unit is lower once trained.
If the demand pattern repeats each year, the approach may provide useful seasonal flexibility.
Difficulties with temporary employees may include:
Two weeks of training reduces how quickly additional supply becomes available.
The peak lasts only three months, so a significant proportion of the period occurs before the new employees are fully trained.
If capacity is already constrained by machinery rather than labour alone, adding workers may not provide enough extra output.
Arguments supporting outsourcing may include:
The external manufacturer can begin immediately.
WaveWear may therefore respond to increased demand more quickly.
This may reduce lost sales during the seasonal peak.
It can use another business's productive capacity rather than relying only on its own.
Difficulties with outsourcing may include:
The outsourced output costs more per unit.
Higher costs could reduce profit margins.
WaveWear depends on the external manufacturer supplying the required output effectively.
Evaluation:
The best option depends on the main constraint.
If WaveWear has enough internal machinery and simply lacks labour, temporary employees could eventually provide the lower-cost solution.
However, if the business needs additional output immediately, outsourcing may be more valuable because the external producer can begin at once. Since the high-demand period lasts only three months, the two-week training delay is significant.
A justified judgement should therefore compare the speed of response provided by outsourcing with the lower cost of temporary labour.
Question 10
"Outsourcing is the best way for all businesses to match supply with changes in demand."
To what extent do you agree?
[25 marks]
Indicative content:
Arguments supporting outsourcing:
External businesses can provide additional output when internal capacity is insufficient.
AQA has directly recognised outsourcing as a way manufacturers can respond to changing consumer demand.
Outsourcing can provide flexibility when increased demand may be temporary.
The business may avoid permanently expanding its own productive capacity.
It may be useful when existing capacity utilisation is high.
Additional supply may prevent lost sales.
Arguments challenging the statement:
Temporary employees may be more suitable where labour is the main constraint.
Part-time employees may be better where demand varies predictably during the day or week.
Producing to order may be more suitable where the problem is excess finished output caused by uncertain demand.
Outsourcing creates dependence on an external business.
External production may be expensive.
If the business has substantial spare capacity, outsourcing may be unnecessary.
If demand falls, reducing surplus internal supply may be more important than finding additional supply.
Evaluation:
Outsourcing can be particularly valuable when customer demand exceeds a business's internal productive capacity and managers do not want to make a permanent increase in capacity. This makes it a flexible response to uncertain or temporary demand.
However, it is not the best solution for every mismatch.
The appropriate method depends on:
whether demand is rising or falling
whether the change is temporary or permanent
current capacity utilisation
whether labour or physical capacity is the limiting resource
the predictability of demand
customer expectations
the cost and reliability of the alternative.
The strongest judgement is therefore that the best approach is the one that addresses the specific cause and timing of the gap between supply and demand, rather than outsourcing being universally superior.
