A business is an organisation that uses resources (land, labour, capital, enterprise) to produce goods or services that people want. This chapter looks at what businesses are, how they are classified and organised, and what they are trying to achieve.

1.1 Business activity

Needs, wants, scarcity and opportunity cost

  • Needs are things essential for survival (food, water, shelter). Wants are things people would like but can live without.
  • Scarcity: resources are limited but wants are unlimited. So people and businesses must choose.
  • Opportunity cost is the next best alternative given up when a choice is made. If a business spends $50,000 on a new machine, it cannot also spend it on advertising: advertising is the opportunity cost.

Specialisation

Specialisation means workers, businesses or regions concentrate on what they do best (division of labour). It raises output and productivity because workers become skilled and faster. Limitations: boredom, and workers who rely on one skill may find it hard to move jobs.

Purpose of business activity

Businesses produce goods and services to satisfy needs and wants, to make a profit, and to provide employment. They do this by adding value.

Adding value

Added value = selling price – cost of the bought-in materials and services.

Ways to increase added value: raise the price (through branding, quality, packaging), cut the cost of inputs (find cheaper suppliers) or produce a higher-quality or more convenient product.

1.2 Classification of businesses

Economic sectors

SectorActivityExamples
Primaryextracting or growing natural resourcesfarming, fishing, mining, oil extraction
Secondarymanufacturing and construction: processing raw materials into productscar factories, bakeries, building
Tertiaryservicesbanking, teaching, transport, retail, healthcare

A bakery that grinds its own flour combines sectors, and many businesses fit more than one. Classify by the main activity.

Changing importance: in developing economies the primary sector is usually largest; as an economy develops, the secondary sector grows (industrialisation), and in developed economies the tertiary sector is the largest, as incomes rise and people spend more on services and manufacturing moves abroad.

Private and public sector

  • Private sector: businesses owned by individuals or groups whose main aim is usually profit (sole traders, companies).
  • Public sector: businesses owned and controlled by the government (public corporations such as a state railway or national health service), usually aimed at providing a service.
  • A mixed economy has both.

1.3 Enterprise, business growth and size

Enterprise and entrepreneurship

An entrepreneur is a person who takes the risk of starting a business. Enterprise is the skill of doing so.

Characteristics of successful entrepreneurs: risk-taker, hard-working, determined, creative or innovative, confident, good at communicating and organising, willing to learn from failure.

A business plan is a written document setting out the business's aims and how it will achieve them. It usually contains: the business idea and aims, market research and the target market, the marketing plan, operations plan, staffing, sources of finance and a cash-flow forecast. It helps entrepreneurs by making them think through the idea, and persuades banks and investors to lend.

Why and how governments support start-ups: because new businesses create jobs, tax revenue and competition. Support includes grants, low-interest loans, training schemes, advice and tax breaks.

Measuring business size

MethodLimitation
Number of employeesmisleading if the business is highly automated (few workers but large output)
Value of output (sales)prices and inflation distort comparisons
Capital employed (money invested)different industries need different amounts of capital
Market sharedepends on how the market is defined

(Profit is not a measure of size: a small business can be highly profitable.)

Why businesses grow, and remain small

Why owners want growth: higher profits, economies of scale (lower average costs), more market share and power, lower risk through diversification, and the owner's status.

Ways to grow:

  • Internal (organic) growth: expanding from within, by selling more, opening new outlets or launching new products. Slow but low risk and keeps control.
  • External growth: merging with or taking over another business. Fast, but costly and risky (clashing cultures).

Problems of growth: diseconomies of scale, poor communication, loss of control, cash-flow problems from heavy investment. Solutions: improve communication, delegation, careful financial planning, hire skilled managers.

Why some stay small: the owner wants control and a quiet life; a niche or personal-service market; not enough finance; the market is too small.

Why businesses fail

Causes: lack of management skills, poor cash flow (liquidity problems), changes in the business environment (new competitors, changes in fashion, recession), low demand, poor location, rising costs. New businesses are at greater risk because they have no track record or reserves, are short of finance, lack experience and customer loyalty, and may be hit by cash-flow problems early on.

1.4 Types of business organisation

The main forms

FormFeaturesAdvantagesDisadvantages
Sole traderowned and run by one person; unlimited liabilityfull control, keeps all profit, simple, privateunlimited liability, limited finance, long hours, no continuity
Partnershiptwo or more owners (usually 2–20); unlimited liability; deed of partnershipshared skills, finance and workloadunlimited liability, disagreements, shared profits
Private limited company (Ltd)shareholders own it; shares cannot be sold to the general public; limited liabilitylimited liability, raises more capital, continues if owner leavesshares hard to sell, less control for owner, more legal rules, accounts available
Public limited company (plc)shares sold on the stock exchange; limited liabilitycan raise large sums, easy to sell sharestakeover risk, loss of control, costs and strict rules, short-termism (pressure for quick profit)
Franchisea business (the franchisee) pays to use a well-known brand and system from the franchisortested business idea, brand and supportfees and a share of profits, limited independence
Joint venturetwo businesses share a project and its costs, risks and profitsshared risk and expertise, access to new marketsdisagreements, profits shared

Unincorporated businesses (sole traders, partnerships) have no separate legal identity from their owners, so the owners have unlimited liability: they are personally responsible for all debts, even if that means selling their home. Limited companies are separate legal entities: shareholders can lose only the money they invested. This is limited liability.

Risk and ownership: the greater the owner's personal risk, the greater the control, but the more they stand to lose.

Public sector organisations include public corporations (owned by the government, run by a board, funded partly by the state, aims such as providing services and jobs).

1.5 Business objectives and stakeholder objectives

Business objectives

Objectives are targets that give direction and let managers measure success. They can change over time (a new business aims for survival; once secure it targets growth).

ObjectiveMeaning
Survivalstaying in business, especially for new firms
Growthincreasing size, sales or the number of outlets
Profitrevenue minus costs; the main aim of most private firms
Market sharethe percentage of total market sales a firm has
Otherscustomer satisfaction, social and environmental goals, quality

Social enterprises exist mainly to achieve a social or environmental purpose (for example, employing disabled people, fair-trade coffee), reinvesting their profits, while still needing to make enough money to survive.

Stakeholders

A stakeholder is anyone affected by or with an interest in a business.

GroupTypeTypical objective
Owners / shareholdersinternalprofit and dividends, growth in value
Managersinternalsalary, status, job security
Employeesinternalgood pay, job security, good conditions
Customersexternalquality, low prices, good service
Suppliersexternalregular orders, prompt payment
Lenders (banks)externalrepayment with interest
Governmentexternaltaxes, jobs, obeying the law
Local communityexternaljobs, no pollution or noise

Conflicts: stakeholders' objectives often clash. Owners want higher profit, which may mean lower wages for employees or higher prices for customers; customers want low prices, suppliers want high prices; the community wants less pollution, which raises costs.

Private and public sector objectives

Private sector: mainly profit, growth, survival, market share. Public sector: mainly to provide a service (healthcare, transport) at an affordable price, create employment, and cover costs rather than maximise profit.
