Enterprise, Business Growth and Size

This guide covers subtopic 1.3 Enterprise, business growth and size, from Topic 1, Understanding business activity, for Cambridge O Level Business Studies 7115, 2026 series.

Where this fits in 7115

Subtopics 1.1 and 1.2 established what business activity is and how businesses are classified. 1.3 moves from classification to a different question: how does a business come into existence, and what happens to it afterwards — does it grow, stay small, or fail? This subtopic has four sub-points (1.3.1–1.3.4) and sits directly before 1.4, Types of business organisation, which covers the legal structures a growing business might adopt.

A note on this syllabus’s validity. 7115 is the current O Level Business Studies syllabus for the 2026 examination series specifically — it is not a multi-year series like most subjects on this site. Cambridge replaces it with 7081 (“Cambridge O Level Business”) from 2027 onward. Always check which syllabus code your own examination series uses.

Syllabus coverage

CAMBRIDGE O LEVEL BUSINESS STUDIES 7115

• Understand the characteristics of successful entrepreneurs (1.3.1)
• Understand the contents of a business plan and how business plans assist entrepreneurs (1.3.1)
• Understand why and how governments support business start-ups, e.g. grants, training schemes (1.3.1)
• Understand methods of measuring business size, e.g. number of people employed, value of output, capital employed — profit is not a method of measuring business size (1.3.2)
• Understand the limitations of methods of measuring business size (1.3.2)
• Understand why the owners of a business may want to expand it, the different ways businesses can grow (internal/external), problems linked to growth and how these might be overcome, and why some businesses remain small (1.3.3)
• Understand the causes of business failure, e.g. lack of management skills, changes in the business environment, liquidity problems, and why new businesses are at greater risk of failing (1.3.4)

7115 is not tiered — every candidate covers all of the above.

Enterprise and entrepreneurship (1.3.1)

An entrepreneur is someone who takes on the financial risk of starting and running a business in the hope of making a profit. Successful entrepreneurs tend to share certain characteristics: they are willing to take calculated risks, show initiative and self-motivation, can spot and act on a gap in the market, and can cope with the uncertainty and long hours that starting a business usually involves.

A business plan is a written document setting out the business idea, its objectives, the target market, how it will be financed, and forecasts of costs, revenue and profit. Business plans assist entrepreneurs in several ways: they force the entrepreneur to think through the practicalities of the idea before committing money to it, they are usually required by banks or investors before they will lend money, and they give the entrepreneur a benchmark against which to measure actual performance once trading begins.

Governments frequently support business start-ups because new enterprise creates jobs and economic activity. Common forms of support include grants (money that does not need to be repaid, often targeted at specific industries or regions), training schemes to build entrepreneurial and management skills, low-interest start-up loans, and advice services. This support matters because new businesses are often undercapitalised and inexperienced, making early failure more likely without it.

Measuring business size (1.3.2)

There is no single agreed way to measure how “big” a business is — several methods are used, each with limitations:

Method	What it measures	Limitation
Number of people employed	Workforce size	A highly automated business can have huge output with few staff
Value of output	Total value of goods/services produced	Doesn’t account for how efficiently that output was produced
Capital employed	Total value of capital invested in the business	Capital-intensive industries will always look “larger” by this measure than labour-intensive ones

Profit is explicitly not a measure of business size — a small business can be highly profitable, while a large one can make a loss. Because each method has weaknesses, examiners often expect you to use more than one measure together, or to justify which measure is most appropriate for a given industry, rather than rely on any single figure.

Why some businesses grow and others stay small (1.3.3)

Owners may want to expand a business to increase profit, market share, or survival prospects (a larger business may be better placed to withstand competition). Growth can happen in two broad ways:

• Internal (organic) growth: increasing sales through existing operations — opening new branches, expanding a product range, entering new markets.
• External growth: growing through takeovers or mergers with other businesses.

Growth brings problems as well as benefits: it can strain cash flow, make communication and control harder as the organisation becomes more complex, and dilute the owner’s original close involvement with customers and staff. These problems can be managed through better financial planning, delegation, and clearer management structures, but they are a genuine constraint on how fast a business can safely expand.

Some businesses deliberately remain small — the owner may prefer to keep personal control, the market itself may be small (a niche product or a very local service), or the extra risk and complexity of growth may simply not be worth it to the owner.

Why businesses fail (1.3.4)

Business failure has several common causes: lack of management skills or experience, changes in the business environment (new competitors, changing customer tastes, economic downturns), and liquidity problems — running out of cash to pay day-to-day bills even if the business is profitable on paper.

New businesses are at greater risk of failing than established ones because they typically have less capital to absorb early losses, less market knowledge and fewer established customer relationships, and their owners often have less business experience to draw on when problems arise.

Common mistakes

• Treating profit as a measure of business size. The syllabus explicitly excludes it — always use employment, output value, or capital employed instead.
• Confusing internal and external growth. Internal growth builds on the business’s own existing operations; external growth happens through combining with another business.
• Assuming small businesses fail more because they are “worse” businesses, rather than because they have less capital, less experience and less established reputation to fall back on.
• Listing business plan contents without explaining their purpose — examiners reward understanding of why each element (forecasts, market research, financing) helps an entrepreneur, not just naming them.
