Business Activity and Classification: Revision Notes

Condensed for the final weeks. For the full explanation, use the Business Activity and Classification study guide.

Needs, wants, scarcity and opportunity cost

A need is something essential for survival (food, shelter); a want is something desired but not essential (a particular brand, a luxury item). Scarcity is the basic economic condition that resources are limited relative to unlimited wants — and scarcity is precisely why every choice involves an opportunity cost: the next-best alternative given up when a choice is made. A business spending its budget on new machinery gives up whatever else that money could have funded, such as staff training or marketing.

Specialisation

Specialisation means an individual, business or region focuses on producing a narrow range of goods or services rather than trying to do everything. This tends to increase output and efficiency, since workers or firms become more skilled at their specific task, but it also creates interdependence — a specialised producer relies on others for everything it doesn’t produce itself.

Why business exists

Businesses combine the factors of production to satisfy needs and wants, and to add value.

added value = selling price - cost of bought-in inputs

Increase it by: branding, quality, convenience, design, after-sales service, speed. Not only by raising price.

Added value is not profit — it ignores overheads such as rent and wages, since profit accounts for all the other costs of running the business beyond just the bought-in inputs themselves.

Classification by sector

Sector	Activity	Examples
Primary	Extracting natural resources	Farming, mining, fishing, forestry
Secondary	Making goods from raw materials	Manufacturing, construction
Tertiary	Providing services	Retail, banking, transport, education

As economies develop, the balance shifts primary → secondary → tertiary (deindustrialisation when secondary declines). Developing economies tend to have a larger share of primary sector activity, while developed economies shift toward a much larger tertiary sector, with secondary sector activity often declining in relative — though not always absolute — terms as service industries grow.

Classification by sector of ownership

• Private sector — owned by individuals, profit motive.
• Public sector — owned by government, provides essential services, may run at a loss for social benefit.

In a mixed economy, this distinction is about ownership specifically, not purpose — a private sector organisation can still provide what is effectively a public service, and a public sector organisation is not automatically non-profit-driven in every case.

Business objectives — change with circumstance

Stage	Typical objective
Start-up	Survival and cash flow
Growing	Growth, market share
Established	Profit, shareholder return
Any	Social and environmental goals

Where this fits in the syllabus

These two subtopics establish the vocabulary the rest of 7115 assumes — why businesses exist at all, and how to categorise the one being studied in any given exam question. The following subtopic, Enterprise, business growth and size, builds directly on the classification and objectives content covered here, so treating this as throwaway background material tends to cause problems once later topics assume it is already secure.

Stakeholders and their interests

Stakeholder	Wants
Owners/shareholders	Profit, return on investment
Employees	Job security, fair pay, conditions
Customers	Quality, low price, service
Suppliers	Prompt payment, repeat orders
Government	Tax, employment, legal compliance
Local community	Jobs, minimal pollution

These conflict — higher wages reduce profit; expansion creates jobs but may disturb the community. Questions almost always ask you to weigh them.

Common mistakes worth avoiding specifically

Confusing needs and wants, or treating scarcity as simply “not enough money” rather than the broader economic condition of limited resources against unlimited wants, is a common error. Opportunity cost is specifically the single next-best alternative given up — not simply “everything else that was given up.” Misclassifying a business’s sector is another frequent trap: a bakery that grows its own wheat, mills flour, and sells bread from a shop spans all three sectors, so classification questions often hinge on identifying the specific activity being asked about, not the business as a whole. And assuming the public sector always means non-profit, or that private sector organisations cannot provide public services, oversimplifies a classification that is genuinely about ownership, not purpose.

Exam traps

• Added value ≠ profit.
• Extraction is primary even when it uses advanced machinery.
• The public sector is government-owned, not the same as a public limited company.
• Objectives change with the business stage — don’t assume profit maximisation always.
• Say which stakeholders conflict and why, rather than listing them.

Self-test

1. A baker buys ingredients for $0.60 and sells the loaf for $2.10. State the added value.
2. Classify: an oil refinery, a fishing boat, a call centre.
3. Why does a new business prioritise survival over profit?
4. Give two ways to add value without raising the price.
5. Name one conflict between shareholders and employees.

Answers: 1. $2.10 − $0.60 = $1.50. 2. Refinery = secondary; fishing boat = primary; call centre = tertiary. 3. Cash flow is tight and failure risk is highest early on; without survival no other objective is achievable. 4. Any two: branding, improved quality, better service, convenience, attractive packaging. 5. Shareholders want costs minimised for higher dividends; employees want higher wages — these pull directly against each other.
