IB DP Business Management Unit 4: Marketing -- Revision Notes

Unit 4 is the second-largest unit by teaching hours (30 hours, tied with Unit 3) and sits alongside the full syllabus guide, which lists all six sub-topics, and the Unit 3 Finance and Accounts revision notes, covering the specification’s other large content unit. These notes work through each Unit 4 sub-topic with the exam-relevant detail and common errors that matter for revision, rather than repeating the sub-topic list on its own.

4.1 Introduction to marketing

Marketing is the management function responsible for identifying, anticipating and satisfying customer requirements profitably. Distinguish market orientation (starting from customer needs and designing products to meet them) from product orientation (starting from what the business can make, then finding customers for it) — a firm’s orientation shapes every later decision in this unit, so identify it first when analysing a case study business.

4.2 Marketing planning

A marketing plan sets objectives (e.g. market share, brand awareness) and the marketing mix strategy to reach them, informed by market research and forecasting. Marketing objectives should link back to the business’s overall (corporate) objectives from Unit 1 — a strong answer connects a marketing decision to the broader business goal it serves, not just to “increasing sales” generically.

4.3 Sales forecasting (HL only)

Sales forecasts predict future sales using past sales data, market research and trend analysis, often via moving averages to smooth out random fluctuation and reveal an underlying trend. Forecasts inform production planning, cash flow planning and stock decisions — a poor forecast has knock-on effects across Units 3 and 5, so this sub-topic is a genuine cross-unit link, not an isolated calculation exercise.

4.4 Market research

Type	Definition	Examples
Primary research	New data collected directly for this purpose	Surveys, interviews, focus groups, observation
Secondary research	Existing data collected for another purpose, reused	Government statistics, industry reports, competitor data
Quantitative research	Numerical data	Sales figures, survey ratings
Qualitative research	Non-numerical, opinion-based data	Focus group discussion, open-ended interview responses

Sampling methods (random, stratified, quota, convenience) each trade off representativeness against cost and speed — be ready to justify which sampling method suits a given business scenario, not just define each one.

4.5 The seven Ps of the marketing mix

The traditional 4 Ps (Product, Price, Place, Promotion) are extended to seven for services and the IB course:

• Product — what is sold, including features, quality, branding and the product life cycle.
• Price — the pricing strategy used (penetration, skimming, cost-plus, competitive).
• Place — the distribution channels used to get the product to the customer.
• Promotion — how the business communicates with and persuades customers.
• People — staff who deliver the product or service and shape customer experience.
• Process — the systems and procedures through which a service is delivered.
• Physical evidence — the tangible cues (environment, packaging, branding materials) that signal quality, especially for services.

People, Process and Physical evidence are the three extended Ps most relevant to services rather than physical products — a strong answer explains why these three matter more for a service business (where the “product” is intangible and experienced, not simply purchased) rather than just listing all seven Ps without differentiation.

4.6 International marketing (HL only)

Marketing across borders must adapt to differences in culture, language, legal requirements and consumer behaviour between markets. Businesses choose between standardisation (one marketing approach used globally, lower cost) and adaptation (tailoring the mix to each local market, higher relevance) — evaluate this trade-off for the specific product and markets in a case study, rather than asserting one approach is always superior.

How Unit 4 is examined

Paper 1’s pre-released statement can draw on marketing content alongside Unit 1 stakeholder analysis or Unit 3 numerical tools in the same unseen case study, so revising the seven Ps in isolation from the rest of the course leaves a real gap – practise identifying which Unit 4 sub-topic a given Paper 1 scenario is really testing, in combination with content from other units. HL students should also expect Paper 2’s quantitative stimulus material to occasionally draw on sales forecasting (4.3) alongside Unit 3’s financial calculations, since both units share a numerical, data-interpretation style of question.

Common mistakes

• Listing all seven Ps without linking any of them to the specific business or product in the question.
• Confusing primary research (new data, collected directly) with secondary research (existing data, reused).
• Treating a sales forecast as a guaranteed figure rather than a prediction with inherent uncertainty.
• Assuming international marketing always requires full standardisation or full adaptation, instead of evaluating the trade-off for the specific context given.

Quick self-test

• Distinguish market orientation from product orientation in one sentence each.
• Name two types of primary research and two types of secondary research.
• Explain why People, Process and Physical evidence matter especially for service businesses.
• Give one advantage of standardisation and one advantage of adaptation in international marketing.
• Explain how a marketing objective should connect to a business’s overall corporate objectives.
