1.1 — Business Sectors, Entrepreneurship & Business Success/Failure

PART A: THE FOUR SECTORS OF ECONOMIC ACTIVITY

1. Primary Sector

Definition: Industries that extract raw materials directly from the earth or nature.

Examples:

• Agriculture (farming crops, livestock)

• Mining (coal, gold, iron ore, diamonds)

• Fishing (commercial fishing fleets)

• Forestry (logging, timber)

• Oil & gas extraction

• Quarrying (stone, sand, gravel)

Characteristics:

• Labour-intensive in developing countries, capital-intensive in developed countries

• Output depends heavily on natural conditions (weather, soil quality, resource availability)

• Often located in rural or remote areas

• Products are raw/unprocessed — sold to secondary sector

• Declining share of GDP in developed economies (deindustrialisation)

• Dominant sector in many developing economies (e.g., agriculture in sub-Saharan Africa)

Challenges:

• Price volatility (commodity prices fluctuate with global supply/demand)

• Environmental regulations increasingly restrictive

• Resource depletion (non-renewable resources)

• Climate change impacts (droughts, floods affecting agriculture)

• Low value-added compared to other sectors

Link to other sectors: Primary sector feeds into secondary (manufacturing) — e.g., iron ore → steel mills → car manufacturing.

2. Secondary Sector

Definition: Industries that transform raw materials into finished or semi-finished goods through manufacturing, construction, or processing.

Examples:

• Manufacturing (cars, electronics, textiles, furniture, food processing)

• Construction (buildings, infrastructure, roads)

• Utilities (electricity generation, water treatment)

• Refining (oil refineries, steel mills)

Characteristics:

• Adds value to primary sector outputs

• Requires significant capital investment (factories, machinery)

• Economies of scale are crucial for competitiveness

• Often concentrated in industrial zones or manufacturing hubs

• Increasingly automated (robotics, AI)

Sub-categories:

• Light industry: Consumer goods (clothing, electronics, food)

• Heavy industry: Capital goods, large-scale production (steel, shipbuilding, machinery)

Trends:

• Offshoring to lower-cost countries (China, Vietnam, Bangladesh)

• Reshoring in some cases due to supply chain risks (post-COVID)

• Industry 4.0 — smart factories, IoT, automation

• Declining share of employment in developed countries

Value chain position: Buys from primary, sells to tertiary (retailers) or directly to consumers.

3. Tertiary Sector

Definition: Industries that provide services rather than tangible goods.

Examples:

• Retail (supermarkets, online shopping)

• Financial services (banks, insurance, investment)

• Healthcare (hospitals, clinics, pharmacies)

• Education (schools, universities, tutoring)

• Hospitality (hotels, restaurants, tourism)

• Transport & logistics (airlines, shipping, delivery)

• Professional services (law, accounting, consulting)

• Entertainment (cinemas, streaming, gaming)

Characteristics:

• Intangible output — cannot be stored or stockpiled

• Often labour-intensive (though increasingly automated)

• Direct interaction with consumers

• Dominant sector in developed economies (70-80% of GDP in UK, USA, Australia)

• Quality is subjective and harder to measure than goods

Growth drivers:

• Rising disposable incomes → demand for services

• Ageing populations → healthcare demand

• Globalisation → financial services, logistics

• Digital transformation → e-commerce, streaming

Key concepts:

• Service quality — reliability, responsiveness, assurance, empathy, tangibles (SERVQUAL model)

• Customer experience — increasingly important differentiator

4. Quaternary Sector

Definition: Knowledge-based industries focused on intellectual activities, information, and R&D.

Examples:

• Research & Development (pharmaceutical R&D, tech innovation)

• Information Technology (software development, data analytics, AI)

• Consulting (management consulting, strategy)

• Education & training (higher education, corporate training)

• Media & creative industries (content creation, design)

• Scientific research (universities, government labs)

Characteristics:

• Highest value-added activities

• Requires highly skilled/educated workforce

• Often located in innovation hubs (Silicon Valley, Cambridge, Singapore)

• Output is knowledge, ideas, information — intangible

• Drives innovation and competitive advantage for economies

Why it's separated from tertiary:

• Distinct focus on creating knowledge rather than applying existing knowledge

• Higher barriers to entry (education, expertise, capital for R&D)

• Strategic importance for national competitiveness

Emerging sub-sector — Quinary sector (sometimes discussed):

• Top-level decision-making: government, healthcare policy, education policy

• Non-profit, public sector leadership

• Not always recognised in IB syllabus but worth knowing

Sector Shifts Over Time (Structural Change)

Clark-Fisher Model: As economies develop, employment shifts from primary → secondary → tertiary/quaternary.

Implications for business:

• Businesses must adapt to sectoral shifts

• Skills requirements change (manual → technical → knowledge)

• Government policy affects sector growth (subsidies, education investment)

PART B: ENTREPRENEURSHIP

Definition

An entrepreneur is an individual who takes the initiative to start and run a new business, bearing the financial risks in hope of profit.

Entrepreneurship is the process of identifying opportunities, mobilising resources, and creating value through innovation and risk-taking.

Characteristics of Entrepreneurs

Motivations for Becoming an Entrepreneur

Financial motivations:

• Profit and wealth accumulation

• Financial independence

• Unlimited earning potential (vs. salaried cap)

Non-financial motivations:

• Independence/autonomy — being own boss

• Pursuing a passion or interest

• Flexibility in work-life balance

• Challenge and personal fulfilment

• Creating a legacy

• Social impact (social entrepreneurs)

• Frustration with current employer/industry

• Identifying a gap in the market

• Family tradition (continuing family business)

Role of Entrepreneurs in the Economy

1. Job creation — SMEs (small/medium enterprises) employ majority of workforce in most economies

2. Innovation — New products, services, processes drive progress

3. Competition — Challenges established firms, benefits consumers

4. Economic growth — Contributes to GDP, tax revenue

5. Wealth redistribution — Creates opportunities in local communities

6. Solving problems — Addresses unmet needs, social issues

7. Regional development — Can revitalise declining areas

Intrapreneurship

Definition: Entrepreneurial behaviour within an existing organisation — employees act like entrepreneurs, innovating and taking initiative.

Examples:

• Google's "20% time" → led to Gmail, Google Maps

• 3M's Post-it Notes invented by employee Spencer Silver

• Sony PlayStation developed by Ken Kutaragi within Sony

Benefits:

• Innovation without startup risk

• Retains talented, ambitious employees

• Diversifies product portfolio

Challenges:

• Corporate bureaucracy can stifle creativity

• Risk-averse culture may resist new ideas

• Resource allocation conflicts

Social Entrepreneurship

Definition: Using entrepreneurial principles to address social, environmental, or community problems — prioritising social impact over profit maximisation.

Examples:

• TOMS Shoes (one-for-one model)

• Grameen Bank (microfinance for poor)

• The Big Issue (magazine sold by homeless people)

• Who Gives A Crap (toilet paper funding sanitation)

Characteristics:

• Triple bottom line: people, planet, profit

• Reinvests profits into social mission

• Measures success by social impact, not just financial returns

PART C: WHY BUSINESSES SUCCEED

Internal Factors (Controllable)

External Factors (Uncontrollable but can be leveraged)

Success Factors by Business Stage

PART D: WHY BUSINESSES FAIL

Statistics

• ~20% of businesses fail in first year

• ~50% fail within 5 years

• ~65% fail within 10 years (Varies by country, industry, economic conditions)

Internal Causes of Failure

External Causes of Failure

Warning Signs of Business Failure

• Declining sales over multiple periods

• Persistent negative cash flow

• Increasing debt, difficulty paying suppliers

• High staff turnover, low morale

• Loss of key customers

• Quality complaints increasing

• Owner working excessive hours with no improvement

• Competitors gaining market share

Strategies to Avoid Failure

1. Maintain cash reserves — minimum 3-6 months operating costs

2. Monitor cash flow — weekly/monthly forecasts

3. Conduct thorough market research — before launch and ongoing

4. Start lean — minimise fixed costs, test before scaling

5. Diversify revenue streams — reduce dependency

6. Stay close to customers — feedback loops, adapt quickly

7. Invest in people — hire well, train, retain

8. Seek advice — mentors, accountants, business advisors

9. Plan for contingencies — scenario planning, insurance

10. Know when to pivot — recognise when something isn't working
