IB DP Business Management Unit 4: Marketing – Revision Notes

Unit 4 is tied for the largest unit by teaching hours at SL (30 hours, tied with Unit 3) and runs to 35 hours at HL (tied with Unit 2), and sits alongside the full syllabus guide, which lists all six sub-topics, and the Unit 3 Finance and Accounts revision notes, covering the guide’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.

This sub-topic also carries the unit’s only two calculations, both assessed:

market share (%)  = (business's sales / total market sales) x 100
market growth (%)  = ((this period's sales - last period's sales) / last period's sales) x 100

A rising market share alongside falling market growth can still mean falling sales in absolute terms, so both figures should be interpreted together, not read as automatically good or bad news in isolation.

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.

Before setting the mix, a marketing plan requires segmentation, targeting and positioning (STP): segmentation divides a market into groups with similar needs (e.g. by demographics, geography, or lifestyle); targeting selects which segment(s) to serve, often choosing between a niche market (a small, specific segment with less competition but a limited customer base) and a mass market (a large segment with more competition but greater sales potential); positioning is how the business wants the product perceived relative to competitors, often mapped on a position map (also called a perceptual map) with two attributes as axes, such as price against quality. A clear unique selling point (USP) – the specific feature that differentiates a product from competitors – underpins effective positioning and should be identifiable from the position map.

4.3 Sales forecasting (HL only)

This sub-topic itself requires no calculation: it asks only for the benefits and limitations of sales forecasting, evaluated for a given business. Forecasts inform production planning, cash flow planning and stock decisions, but they rest on past data and assumptions about the future, so a strong evaluation weighs the value of planning ahead against the risk of an inaccurate forecast in a fast-changing market.

The trend-forecasting calculation itself sits in the quantitative toolkit rather than this sub-topic: simple linear regression (HL only) plots data on a scatter diagram, fits a line of best fit, uses correlation to judge how reliable that line is, and extrapolates it forward to forecast a future value. Revise the toolkit technique separately from this sub-topic’s own focus on evaluating forecasting’s usefulness.

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, 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 present a sales forecast alongside Unit 3’s financial calculations: evaluating it belongs to 4.3, while calculating a trend belongs to the HL toolkit’s simple linear regression.

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

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

Answers: 1. Market orientation starts from customer needs and designs products to meet them; product orientation starts from what the business can make and then finds customers for it. 2. Primary: surveys and interviews (or focus groups, observation). Secondary: government statistics and industry reports (or competitor data). 3. Because a service’s “product” is intangible and experienced rather than simply purchased, the people delivering it, the process customers go through, and the physical evidence surrounding the service all shape the customer’s perception of quality in a way that does not apply in the same way to a physical product. 4. Standardisation: lower cost, since one marketing approach is used globally. Adaptation: higher relevance, since the mix is tailored to local culture, language, legal requirements and consumer behaviour. 5. A marketing objective (e.g. a sales or market share target) should be set so that achieving it directly supports the business’s wider corporate objectives (e.g. growth or profit maximisation), rather than being pursued in isolation from what the business as a whole is trying to achieve.
