Cambridge A Level Business 9609

Business size and growth

Business size can be measured several ways, small businesses have real advantages as well as weaknesses, and growth comes either from within (organic) or by joining with another business (external) — and most questions on this topic end in a judgement about whether growing, or growing that particular way, is right for the business in the case.

That makes it an evaluation topic more than a definitions one — the counts from real papers further down show where its marks sit. The marks go to answers that weigh the gains of size against what the business would lose.

Measuring the size of a business

  • Number of employees — simple, but flatters labour-intensive businesses and understates highly automated ones.
  • Revenue (sales turnover) — comparable within an industry, but a supermarket’s revenue dwarfs a jeweller’s of similar importance.
  • Capital employed — the long-term finance invested; favours capital-intensive industries.
  • Market share — size relative to rivals, meaningless across industries.
  • Market capitalisation — share price × number of shares; only for public limited companies, and moves with the stock market.

The examinable point is appropriateness: no single measure works for every business, so the right one depends on the industry and the purpose of the comparison. Using two measures together is the strongest answer.

Small and family businesses

Advantages of being small: flexibility and quick decisions, personal service and close customer relationships, low overheads, motivated owners, and the ability to serve niche markets too small for large firms. Disadvantages: no economies of scale, so higher unit costs; difficulty raising finance; reliance on a few people and customers; limited specialist expertise.

Family businesses add strengths — commitment, trust, a long-term view, shared values — and weaknesses: conflict between family and business decisions, succession problems, and promotion by family rather than merit.

Small businesses matter to the economy: they create jobs, start most new ideas, supply large firms, keep markets competitive and grow into the large businesses of the future.

Internal (organic) growth

Growing from within — more products, new branches, new markets, financed largely from retained profit. It is lower risk, keeps control and culture intact, and avoids the cost and disruption of combining two organisations. It is also slow, limited by the business’s own profits, and may be too late to seize an opportunity a competitor is about to take.

External growth: mergers and takeovers

A merger joins two businesses by agreement into one. A takeover (acquisition) is one business buying a controlling stake in another. A friendly takeover is supported by the target’s board; a hostile takeover is made against its wishes, usually by buying shares directly from its shareholders.

External growth is fast and buys market share, brands, skills or technology at once; it is expensive, often financed by debt, and brings the integration problems below.

Horizontal, vertical and conglomerate

TypeJoins withTypical gain
HorizontalA business at the same stage of the same industry (a rival)Market share, economies of scale, less competition
Vertical backwardA supplierControl of supply, quality and input costs
Vertical forwardA customer or outletGuaranteed outlets, control of how the product reaches buyers
ConglomerateA business in an unrelated industrySpreads risk across markets

A merger affects every stakeholder differently: shareholders hope for higher profit; employees fear duplicated jobs being cut; customers may gain from scale or lose from less competition; suppliers may gain a bigger customer or be replaced. Questions that ask for the impact on one stakeholder want that stakeholder followed through, not a list.

Why mergers succeed or fail

The reasons a merger may achieve its objectives: economies of scale, cross-selling to each other’s customers, combined expertise, removal of a competitor. The reasons many do not:

  • Paying too much — the price assumed savings that never arrive.
  • Culture clash between two ways of working, damaging motivation.
  • Diseconomies of scale — coordination and communication problems in a larger business.
  • Loss of key staff and customers during the uncertainty.
  • Management distracted from running the business by integrating it.

A balanced 12-mark answer weighs the expected synergies against these, and lands on what the outcome depends on — usually how well the two cultures are integrated.

Joint ventures and strategic alliances

A joint venture creates a new business owned by two or more partners for a shared project; a strategic alliance is an agreement to cooperate without creating a new business. Both share costs, risks and expertise and give access to new markets — at the price of shared control and profit, and the risk of the partners’ aims diverging.

How Cambridge asks it

On the 36 AS papers Quanta holds, 19 question parts test size of business, on 16 of the papers (10 on Paper 1, 9 on Paper 2). The command words they open with:

  • Evaluate × 8
  • Analyse × 4
  • Identify × 3
  • Explain × 2
  • Define × 2

By tariff — each size has its own technique:

Common mistakes

  1. 1.Merger and takeover used as the same thing

    A merger is by agreement into one business; a takeover is one business buying control of another.

  2. 2.Backward and forward vertical integration reversed

    Backward is towards suppliers (the raw materials); forward is towards customers.

  3. 3.Assuming bigger is always better

    Growth brings diseconomies of scale and loses the flexibility and personal service that may be the business’s whole advantage. Weigh both.

  4. 4.Number of employees recommended for every business

    Choose the measure that suits the industry, and say why the others would mislead.

Common questions

What is the difference between organic and external growth?

Organic growth comes from within — new products, branches or markets, usually financed by retained profit. External growth comes from merging with or taking over another business: faster, but costlier and riskier.

What is a hostile takeover?

Buying control of a business against the wishes of its directors, usually by buying its shares directly from shareholders.

What is vertical integration?

Joining with a business at a different stage of the same supply chain — backward with a supplier, forward with a customer or retailer.

Why do many mergers fail?

Overpaying, culture clash, diseconomies of scale, losing key staff and customers, and management distraction during integration.
