A strong Paper 4 essay explains how a strategy affects the business, whether it can achieve the relevant objective, and why your final judgement is justified.

You need accurate business knowledge, relevant case evidence, developed reasoning and a clear decision. Listing advantages and disadvantages is only a starting point: you must explain their consequences and decide which matter most.

This guide shows you how to plan your answer, develop analysis, evaluate a strategy as a whole and write a convincing conclusion. It also includes an original practice case and an annotated model essay.

The essentials

  • The paper: 1 hour 15 minutes, two compulsory 20-mark essays on one case study.
  • The marks: 15 of every 20 are for analysis (8) and evaluation (7).
  • The top analysis band rewards analysis of the overall strategy, not just individual parts.
  • The conclusion must make a supported decision, not say "it depends".

What is Cambridge Business Paper 4?

Paper 4 is Business Strategy. Under the 2026–2028 syllabus, which applies to 2027 exams, it is a 1 hour 15 minute written paper worth 40 marks, with two compulsory essay questions worth 20 marks each, both based on a case study.

Questions are based on the A Level content (topics 6.1–10.4), with the AS Level content assumed knowledge, and both answers must show evaluation.

Start by identifying the exact task:

Question asks you to…Your answer needs to…
Evaluate a past strategyAssess how successful it was, using evidence of outcomes and limitations
Advise on a future decisionRecommend a suitable course of action and explain why it is preferable
Evaluate a strategic approachAssess its usefulness and limitations for this business
Assess achievement of an objectiveJudge performance against that objective

Watch out

If the question names an objective or a time period, use it throughout your answer. Revenue growth, profit growth and market share are different measures, so judge the strategy using the measure the question asks about.

How are the 20 marks awarded?

Cambridge's specimen Paper 4 mark scheme uses this split for each essay:

Assessment objectiveMarksWhat your answer should show
AO1: Knowledge and understanding3Accurate understanding of relevant business concepts
AO2: Application2Relevant use of the particular business's circumstances
AO3: Analysis8Explained connections between causes, impacts and consequences
AO4: Evaluation7A supported judgement that weighs arguments in context

Key point

Analysis and evaluation are worth 15 of the 20 marks. The marking grid separates analysis of individual strategic elements (up to 6 marks) from analysis of the overall strategy (7–8 marks), and the top evaluation band needs a developed judgement in the business context that draws together evaluative comments weighing up key arguments.

So keep definitions brief, and spend most of the essay explaining consequences and judging how much they matter.

Show accurate business knowledge

Show that you understand the concept being examined.

Example

"A joint venture involves businesses combining resources in a jointly owned enterprise, sharing control and risk under their agreement."

A short definition is a useful starting point, but a separate definition paragraph is not compulsory. You can also show knowledge through accurate explanations within your arguments. The marking grid credits knowledge "used to answer the question", so show understanding, then use it.

Use frameworks to explain decisions

Naming a framework does little to show how it helps.

Rather than

"Kestrel should use Ansoff's matrix."

Try

"Entering a new overseas market with existing products is market development. Although Kestrel knows its products, unfamiliar customers and distribution arrangements increase uncertainty about demand."

The stronger version explains the concept and connects it to the decision. You do not need every framework you remember; use the theory that helps explain the case.

Use case evidence to explain something

Application means using the business's circumstances to shape your argument.

Rather than

"Kestrel has $3m in cash reserves."

Try

"Investing $2.5m would use about 83% of Kestrel's $3m cash reserves, leaving only $0.5m to cover unexpected cash needs."

The stronger version turns a figure into a meaningful constraint. Useful evidence includes:

  • revenue, profit, cash and borrowing;
  • objectives and deadlines;
  • customer preferences and market conditions;
  • employee skills and management experience;
  • production capacity and supplier relationships;
  • previous decisions and their outcomes.

Ask yourself

"What does this detail change about the argument or decision?"

Simply adding the business's name to a generic point does little to show its circumstances.

Make simple calculations when they help

A calculation can reveal the scale of an opportunity or a risk:

  • How much cash remains after an investment?
  • How much extra revenue is needed to hit the target?
  • Has profit grown faster or more slowly than revenue?
  • Can existing capacity meet forecast demand?

Tip

Always explain what the result means. A calculation without interpretation leaves the important reasoning unfinished.

Develop analysis: explain how and why

Analysis explains the steps connecting a decision to its consequences. A useful planning pattern is:

The chain

Case evidence → immediate effect → further consequence → relevance to the question

This is a writing aid, not a compulsory number of links.

Rather than

"A joint venture gives Kestrel access to more shops, increasing sales."

Try

"Norden has contracts with 400 retail outlets. Its existing retailer relationships could help Kestrel secure distribution more quickly than building contacts on its own. Wider availability would create more opportunities for customers to buy Kestrel's clothing, supporting its target of 30% revenue growth within three years."

The developed version explains why the distribution network matters and connects it to the objective. You can then qualify it:

Example

"However, the contracts do not guarantee that retailers will stock Kestrel's products or that customers will buy them. The network's value therefore depends on retailer interest and demand for the premium range."

That avoids assuming a potential benefit will definitely happen.

Keep the outcome relevant

Not every argument needs to end with "higher profit".

Question focusRelevant consequences
Revenue growthSales volume, prices, distribution and demand
ProfitabilityRevenue, costs, margins and investment returns
Operations strategyProductivity, quality, capacity, delivery and costs
HR strategyRecruitment, retention, skills and their effect on the required performance
Overall strategic successAchievement of objectives, feasibility and longer-term consequences

Analyse the strategy as a whole

Paper 4 asks you to consider how strategic decisions work together. A marketing campaign may increase demand, but the business also needs the capacity and working capital to fulfil the extra orders.

Example

"Faster expansion through Norden's retailers could increase orders, but supplying those orders may require more inventory and longer credit periods. The joint venture therefore creates a financing need at the same time as its initial investment reduces Kestrel's cash reserves."

Here, the growth argument changes the significance of the cash-flow argument. That is more useful than discussing "more sales" and "less cash" as separate observations, and it is what the top analysis band ("developed analysis of the overall strategy") describes.

Other useful connections include:

  • premium positioning and the choice of distribution outlets;
  • automation and the need for employee training;
  • expansion and the availability of finance;
  • cost reduction and its possible effect on quality.

Check

Ask whether the strategy's elements support each other or create a conflict.

Evaluate: decide which arguments matter most

Analysis explains a possible consequence. Evaluation judges its significance.

Analysis

"The investment leaves Kestrel with $0.5m in cash, increasing its exposure to unexpected payments."

Evaluation

"This may outweigh the benefit of faster overseas distribution because domestic sales still provide 90% of revenue. Cash shortages that disrupt the existing operation could undermine the overall growth objective."

The evaluative version explains why one argument deserves more weight.

Useful criteria for evaluation

CriterionQuestion to ask
ScaleHow large is the benefit or risk?
LikelihoodHow convincing is the evidence that it will happen?
TimingWill the benefit arrive within the relevant period?
FeasibilityCan the business finance and carry out the strategy?
Trade-offsWhat must the business give up?
ConditionsWhat could change the decision?

Choose the criteria that matter for this case; you do not need to cover every row.

Write a conclusion that makes a decision

A useful conclusion answers four questions:

  1. What is your judgement?
  2. What is the strongest reason for it?
  3. Why does that reason outweigh the main counterargument?
  4. What important condition could change your decision?

Example conclusion

"Kestrel should initially use an export agent. Norden's network could accelerate entry, but the proposed investment would leave only $0.5m in cash and may make expansion difficult to sustain. The joint venture would become more attractive if suitable finance protected working capital and firm retailer commitments supported the sales forecast."

Remember

A conditional judgement still makes a decision. "It depends on many factors" leaves the decision unexplained.

A practical five-minute essay plan

Before writing, make brief notes on five areas:

Planning stepWhat to write
Exact taskThe judgement required, including any objective or period
Relevant knowledgeThe concept you need to explain
Main argumentsTwo or three important issues, with evidence and consequences
Strategic connectionHow one issue affects another
Provisional judgementYour answer, strongest reason and decisive condition

Two or three substantial issues are a useful starting point. There is no fixed requirement for three arguments or five paragraphs, and following a particular structure does not guarantee a mark. Choose arguments you can develop properly.

A flexible essay structure

PartWhat it does
OpeningExplains the relevant concept briefly and identifies the decision or criteria
Main argumentUses case evidence, explains consequences and assesses their significance
Counterargument or alternativeDevelops the strongest competing case and why it matters for this business
Strategic connectionShows how the issues interact (this can sit inside the paragraphs above)
Final judgementAnswers the question directly and explains why your decision follows from the evidence

Adapt the structure to the question rather than forcing every answer into identical paragraphs.

Annotated model essay: joint venture or export agent?

Practice case

Kestrel Outdoor (original case).

Kestrel Outdoor produces premium outdoor clothing. It employs 280 people, earns annual revenue of $42m and gets 90% of its revenue from domestic sales. Cash reserves are $3m.

Kestrel aims to increase annual revenue by 30% within three years through overseas expansion. It has no international business experience.

Norden AS, a Scandinavian distributor with contracts at 400 retail outlets, offers a 50/50 joint venture requiring Kestrel to invest $2.5m. Alternatively, Kestrel could use an export agent charging 12% commission on export sales.

Question: Evaluate whether Kestrel should enter international markets through the joint venture with Norden rather than through an export agent. [20]

Paragraph 1: knowledge and decision criteria

A joint venture is a jointly owned enterprise in which businesses combine resources and share control and risk under an agreement. An export agent helps arrange overseas sales in return for commission. Kestrel must compare the potential speed of expansion through Norden with the financial commitment required. Its 30% target means increasing annual revenue from $42m to $54.6m within three years.

Why this works: it explains both alternatives and calculates the scale of the objective.

Paragraph 2: the case for the joint venture

Norden's contracts with 400 retail outlets could help Kestrel gain distribution faster than establishing retailer relationships on its own. This is valuable because Kestrel has no international experience: Norden may help it understand local buying practices and choose suitable outlets for premium clothing. Faster access to customers could bring export revenue forward, improving the chance of meeting the three-year target. However, the contracts do not show that all 400 outlets will stock Kestrel's range. Without evidence of retailer commitments and consumer demand, market access alone does not show that the extra $12.6m of annual revenue is achievable.

Why this works: it develops a benefit, connects it to the target and evaluates the strength of the evidence.

Paragraph 3: the financial constraint and strategic connection

The joint venture would use about 83% of cash reserves, leaving $0.5m. Overseas growth may also require extra inventory, transport spending and credit to buyers before receipts arrive. Faster distribution could therefore increase working-capital needs precisely when the investment reduces available cash. If Kestrel cannot fund extra orders, Norden's network may not deliver the expected growth. Domestic sales currently provide $37.8m of revenue, so disruption to the existing operation could offset overseas gains. The investment cannot be assessed separately from the financing needed to make the expansion work.

Why this works: it connects market access, working capital and domestic performance, assessing the overall strategy.

Paragraph 4: the alternative and its limitations

The agent avoids the $2.5m equity investment, while commission varies with export sales. This gives Kestrel more flexibility to test demand before committing substantial capital. Nevertheless, exporting still creates production, delivery and working-capital costs. Commission also reduces the amount retained from sales: $1m of export revenue would incur $120,000 in commission. At sustained high sales this could make the agent less attractive, but the case gives neither profit margins nor joint-venture returns, so it cannot show which route is more profitable. Equally, an agent does not automatically control pricing, while 50/50 ownership does not guarantee Kestrel can impose its preferred decisions.

Why this works: it evaluates the alternative without treating it as cost-free or assuming contractual powers.

Paragraph 5: supported judgement

Kestrel should initially use an export agent rather than accept the joint venture on the stated terms. Norden offers a credible advantage in speed, especially given Kestrel's inexperience, but the cash commitment could prevent the business from supporting that growth. Preserving funds for production and the domestic operation is therefore the stronger consideration. The joint venture would become preferable if Kestrel secured suitable finance with affordable repayments, obtained convincing retailer commitments and agreed workable decision-making arrangements with Norden. Until then, an agent provides a more manageable first stage of expansion, although the 30% target remains uncertain.

Why this works: it makes a clear choice, ranks the arguments and names specific conditions that could change the decision.

Note

This is an illustrative teaching answer, not an officially marked Cambridge response.

Your turn

Using the Kestrel case, how much export revenue would Kestrel need each year to hit its target if domestic revenue stayed at $37.8m, and how much commission would an agent take on that?

AnswerShow answer

The target is $54.6m. With domestic revenue unchanged at $37.8m, Kestrel would need $16.8m of non-domestic revenue (the current $4.2m plus $12.6m more, assuming all the growth comes from overseas). At 12%, an agent would take $2.016m a year in commission on $16.8m of export sales.

Frequently asked questions

How many paragraphs should I write?

There is no compulsory number. A short opening, several developed discussion paragraphs and a clear conclusion usually work well. Use paragraph breaks to separate ideas clearly.

Do I need exactly three arguments?

No. Choose enough issues to answer the question fully, and develop them properly. Two substantial issues can be more effective than several superficial ones.

How long should a 20-mark essay be?

There is no prescribed word count. Practise completing developed arguments and a supported judgement within your time allocation; word count alone does not show quality.

Should evaluation appear only in the conclusion?

No. Use brief evaluative comments during the discussion to judge significance and limitations, then bring the most important arguments together in the conclusion.

Do I have to use numbers?

Use relevant figures when they strengthen the reasoning. Simple calculations can clarify scale, but customer preferences, skills and competition can also provide useful application.

Can I say that more information is needed?

Yes, but name the information and explain how it would affect the decision, then still give the strongest judgement the evidence supports.

Rather than

"More information is needed."

Try

"Firm retailer orders would help show whether Norden's network can generate enough extra sales to justify the investment. Without them, the agent is the more manageable first option."

Can a conclusion develop an earlier point?

Yes. It can explain more clearly why an earlier argument is decisive. Avoid replacing that judgement with a new major argument you have not analysed.

What should I practise before the exam?

Practise three skills separately, then combine them in timed essays:

  1. Turning case evidence into developed reasoning.
  2. Connecting different strategic issues.
  3. Writing conclusions that rank arguments and explain a decision.
