Methods of Business Expansion Revision Notes | GCSE AQA Business

1. Why Businesses Expand — and Why the Method Matters

A small bakery in Manchester sells out every morning. The owner has a choice: open a second shop, sell the recipe to someone else, or buy out a rival. Each option leads to growth — but the risks, costs, and rewards are completely different. That choice is what this lesson is about.

Businesses expand to increase revenue, gain market share, achieve economies of scale, or reduce competition. But expansion is never risk-free. The method a business chooses shapes everything: how fast it grows, how much control it keeps, and how much it costs.

There are two broad categories of expansion: organic growth (growing from within) and external growth (growing by joining with or acquiring another business). Both have a place in the real world — the skill is knowing which fits the situation.

2. Organic Growth — Building From the Inside

Organic growth happens when a business expands using its own resources. Think of it like a plant growing from its own roots rather than being grafted onto another. It is slower, but the business retains full control over its direction, culture, and quality.

There are several routes to organic growth. Each suits a different type of business and carries its own trade-offs. The four main methods you need to know for AQA are: opening new stores, franchising, e-commerce, and outsourcing.

2a. Opening New Stores

The most direct form of organic growth is opening additional physical locations. Greggs, the bakery chain, grew from a single shop in Newcastle to over 2,400 outlets across the UK by replicating its model in new locations. Each new store brings in new revenue and increases brand visibility.

The downside is cost. New premises, staff, and stock all require significant upfront investment. If the new location underperforms, the business absorbs the loss entirely. This method also takes time — finding the right site, fitting it out, and building a local customer base does not happen overnight.

2b. Franchising

McDonald's is the classic example. Rather than funding every new restaurant itself, McDonald's allows individual franchisees to open and run outlets. The franchisee takes on the financial risk of the new location, while McDonald's collects fees and royalties. This allows McDonald's to expand rapidly without tying up its own capital.

For the franchisee, the appeal is clear: they get a proven business model, brand recognition, and ongoing support. The risk of starting from scratch is significantly lower than launching an independent business. However, they must follow the franchisor's rules strictly — there is little room for independent decision-making.

The franchisor's risk is reputational. If one franchisee delivers poor service or cuts corners on hygiene, it damages the whole brand. This is why franchisors invest heavily in training, monitoring, and quality standards — but they can never fully eliminate the risk of a franchisee behaving badly.

2c. E-Commerce

E-commerce means selling goods or services online. For many businesses, launching a website or selling through platforms like Amazon or Etsy is the most cost-effective way to reach new customers. There is no need to pay rent on a physical store, and the business can trade around the clock, reaching customers nationally or internationally.

ASOS built its entire business model on e-commerce, growing from a small online retailer to a global fashion brand without a single high-street store. The low overhead costs allowed it to offer competitive prices and invest heavily in marketing and logistics instead.

The challenge is standing out in a crowded digital marketplace. Search engine optimisation, digital advertising, and customer reviews all matter enormously. Delivery and returns logistics can also eat into profit margins — particularly for businesses selling heavy or bulky goods.

2d. Outsourcing

Outsourcing is not always the first thing students think of when they hear 'expansion', but it supports growth by freeing up resources. If a growing business outsources its payroll processing to a specialist firm, its own staff can focus on core activities that drive revenue.

Nike outsources most of its manufacturing to factories in Vietnam and Indonesia. This keeps production costs low and allows Nike to focus on design, marketing, and brand development — the areas where it adds the most value. The trade-off is reduced control over working conditions and quality, which has caused reputational problems in the past.

3. External Growth — Mergers and Takeovers

External growth is a faster but riskier route to expansion. Instead of building from within, the business grows by combining with or acquiring another business entirely. This can dramatically increase market share, eliminate a competitor, or provide access to new products, markets, or technologies almost immediately.

The merger between Sainsbury's and Asda (proposed in 2018) is a well-known UK example. The two supermarkets planned to combine to create a business large enough to challenge Tesco's market dominance. The Competition and Markets Authority ultimately blocked it — a reminder that external growth is subject to regulatory scrutiny.

A takeover can be friendly or hostile. In a friendly takeover, the target company's board agrees to the deal. In a hostile takeover, the acquiring business buys shares directly from shareholders, bypassing management. Hostile takeovers are controversial and can damage employee morale and company culture significantly.

One major risk of external growth is the clash of company cultures. When two businesses merge, they bring different management styles, working practices, and values. If these are not carefully managed, staff morale can fall, key employees may leave, and productivity can drop — undermining the very benefits the merger was supposed to deliver.

4. Calculating and Interpreting Market Share

One of the key reasons businesses expand is to increase their market share — the percentage of total sales in a market that a business controls. Examiners often ask you to calculate market share and then use it to evaluate the success of an expansion strategy. Here is the formula you need.

Now let us walk through a realistic exam-style calculation. Pay attention to how the number is interpreted — that is where the marks are often lost.

Worked example: Calculating Market Share After Expansion

SuperFit, a gym chain, had annual revenue of £8 million. After acquiring a rival gym chain, its revenue increased to £14 million. The total UK gym market is worth £70 million. Calculate SuperFit's market share before and after the acquisition, and comment on the result.

1. Market Share (%) = (Business Sales / Total Market Sales) x 100 — Always state the formula first — this earns a method mark even if you make an arithmetic error later.
2. Market Share (before) = (8,000,000 / 70,000,000) x 100 = 11.43% — 8 divided by 70 = 0.1142857... Multiply by 100 = 11.43% (rounded to 2 decimal places). SuperFit held just over one-ninth of the market.
3. Market Share (after) = (14,000,000 / 70,000,000) x 100 = 20% — 14 divided by 70 = 0.2. Multiply by 100 = 20%. The acquisition doubled SuperFit's market share from approximately 11.4% to exactly 20%.
4. Market share increased by 8.57 percentage points (20% - 11.43% = 8.57%) — This is a significant gain. SuperFit now controls one-fifth of the UK gym market, giving it greater bargaining power with suppliers and a stronger competitive position against rivals.
5. 20% of £70m = £70m x 0.20 = £14m. This matches SuperFit's post-acquisition revenue. — Always verify your answer makes sense. If your calculated market share gave a revenue figure that did not match the data, you would know to recheck your working.

Answer: SuperFit's market share increased from 11.43% to 20% following the acquisition — a gain of 8.57 percentage points. This suggests the takeover was an effective method of rapid expansion, significantly strengthening SuperFit's competitive position in the UK gym market.

Looking at the chart, SuperFit's acquisition has moved it from the smallest named competitor to the second-largest player in the market. This kind of visual comparison is exactly what examiners expect you to interpret in data-response questions. Notice that 'Others' still holds the largest combined share — this tells us the market remains fragmented, and further consolidation is possible.

5. Stakeholder Impact of Expansion Decisions

Expansion does not affect everyone in the same way. Different stakeholders experience the same decision very differently — and in evaluation questions, showing awareness of these conflicting perspectives is what separates a Level 2 response from a Level 3 one.

Consider a business that grows through a takeover. Shareholders may celebrate — the combined business has greater market power and the potential for higher profits and dividends. But employees of the acquired company face uncertainty: will their jobs survive? Will their pay and conditions change? These are legitimate concerns that a well-rounded answer must address.

Worked example: Evaluating a Merger Decision — Stakeholder Perspective

Priya runs a regional supermarket chain with 15 stores. She is considering merging with a national competitor to increase market share and reduce costs. Evaluate whether this merger is the right decision for Priya's business. [12 marks]

Method: Stakeholder Analysis + Balanced Evaluation + Justified Conclusion

1. The merger would give Priya's business immediate access to the national competitor's store network, customer base, and supply chain. This could significantly increase market share and allow the combined business to negotiate better prices from suppliers — reducing costs and improving profit margins. — Start with a developed point that links the method of expansion to a specific business outcome.
2. Shareholders of Priya's business would likely benefit in the long term. Greater market share and lower costs should lead to higher operating profits, which could translate into increased dividends and a higher share price. — Apply the stakeholder lens — shareholders care about profit and return on investment.
3. However, mergers carry significant risks. Cultural clashes between the two businesses could reduce productivity. Employees may face redundancy if roles overlap — for example, head office functions like HR and finance may be duplicated. This could damage morale and lead to the loss of experienced staff. — The counter-argument must be developed, not just stated. Show the chain of consequences.
4. The Competition and Markets Authority (CMA) may investigate the merger if it significantly reduces competition in the regional grocery market. The proposed Sainsbury's-Asda merger was blocked on exactly these grounds in 2019. If the CMA blocks the deal, Priya's business will have wasted significant management time and legal costs. — Real-world context strengthens the analysis and demonstrates application beyond the textbook.
5. On balance, the merger could be the right decision if Priya's business has the management capacity to handle integration and if the combined market share does not trigger CMA intervention. However, if the cultural fit between the two businesses is poor, the risks to employee morale and productivity may outweigh the financial benefits. — A strong conclusion weighs the evidence and reaches a conditional judgement — it does not repeat the arguments.

Answer: The merger offers Priya's business significant potential benefits, including increased market share, greater bargaining power with suppliers, and improved profit margins. However, the risks of cultural clashes, employee redundancies, and potential CMA intervention are substantial. On balance, the merger is likely to be the right decision only if Priya conducts thorough due diligence on the target business and has a clear integration plan. Without these safeguards, the short-term disruption could undermine the long-term gains.

6. Exam Technique — Answering Expansion Questions

Expansion questions appear regularly in AQA Business Studies papers, and they follow predictable patterns. The command word tells you exactly how much depth is expected. 'Identify' wants a term. 'Explain' wants a cause-and-effect chain. 'Evaluate' wants both sides and a conclusion. Matching your response to the command word is the single most reliable way to pick up marks.

A common trap in expansion questions is writing about the wrong type of growth. If the question asks about organic growth, do not drift into discussing mergers. If it asks you to evaluate franchising specifically, do not give a generic answer about 'all methods of expansion'. Examiners reward precision and application to the specific context given.

For calculation questions involving market share, always show the formula, substitute the values, and then interpret the result. A bare number with no comment will lose the final mark. The interpretation does not need to be long — one sentence explaining what the figure means for the business is enough.
