IB DP Business Management Unit 4: Marketing

This guide covers Unit 4 — Marketing, for IB Diploma Programme Business Management, first assessment 2024. At SL, Unit 4 is tied with Unit 3 as the largest unit (30 recommended teaching hours each); at HL it runs to 35 hours, behind Units 3 and 5 (45 hours each), as the full syllabus guide sets out.

Where this fits in the syllabus

Paper 1’s pre-released statement can draw on marketing content alongside Unit 1 stakeholder analysis or Unit 3 numerical tools within 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.

Syllabus coverage

IB DP BUSINESS MANAGEMENT — UNIT 4: MARKETING

• 4.1 Introduction to marketing — marketing as the management function responsible for identifying, anticipating and satisfying customer requirements profitably; market orientation (starting from customer needs) versus product orientation (starting from what the business can make)
• 4.2 Marketing planning — setting objectives (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
• 4.3 Sales forecasting (HL only) — the benefits and limitations of sales forecasting; the sub-topic has no calculation method of its own (the trend calculation, simple linear regression, sits in the HL toolkit), and forecasts inform production, cash flow and stock decisions across other units
• 4.4 Market research — primary versus secondary research; quantitative versus qualitative research; sampling methods (random, quota, convenience), each trading off representativeness against cost and speed
• 4.5 The seven Ps of the marketing mix — Product, Price, Place, Promotion, and the three extended Ps especially relevant to services: People, Process, and Physical evidence
• 4.6 International marketing (HL only) — adapting to differences in culture, language, legal requirements and consumer behaviour between markets; standardisation (one global approach, lower cost) versus adaptation (tailored to each local market, higher relevance)

How to approach it

Identify a case-study business’s market or product orientation first, since this shapes every later marketing decision analysed in a question. Always connect a marketing objective back to the business’s broader corporate objective from Unit 1, rather than describing it only in terms of “increasing sales” generically. For market research, be ready to justify which sampling method suits a given business scenario, not just define each one — the trade-off between representativeness, cost and speed is what evaluative questions target. For the seven Ps, explain specifically why People, Process and Physical evidence matter more for a service business (where the “product” is intangible and experienced, not simply purchased) rather than listing all seven without differentiation. For international marketing, evaluate the standardisation-versus-adaptation trade-off for the specific product and markets given in a case study, rather than asserting one approach is always superior.

Worked example: distinguishing market and product orientation

A case study describes two competing businesses: one that surveys customers extensively before designing a new product, and one that develops a product based on its existing manufacturing expertise and then looks for buyers.

Business A:   surveys customers first, designs product to match
              identified needs -- MARKET ORIENTATION

Business B:   develops product from existing capability, then seeks
              buyers -- PRODUCT ORIENTATION

Analytical    Business A's marketing decisions (pricing, promotion,
point:        distribution) will be built around confirmed customer
              demand; Business B's marketing decisions will need to
              work harder to persuade customers a product they did
              not ask for is worth buying -- this difference in
              orientation shapes every later marketing decision each
              business makes, not just its initial product design

Identifying orientation explicitly and explaining its knock-on effect on later marketing decisions, rather than only describing what each business did, is what a strong Unit 4 answer does.

Sales forecasting and its cross-unit consequences

Because sales forecasts feed directly into production planning, cash flow planning and stock decisions, a poor forecast has knock-on effects across Units 3 and 5 – this makes 4.3 a genuine cross-unit link rather than an isolated calculation exercise. What 4.3 itself asks for is an evaluation of the benefits and limitations of forecasting for the business in question: a forecast helps plan ahead, but it rests on past data and assumptions that may not hold in a fast-changing market. Where a trend has to be calculated, the method is the HL toolkit’s simple linear regression – a scatter diagram, a line of best fit, correlation to judge how reliable that line is, and extrapolation to a future value. When a case study presents a forecast, check what it implies for other parts of the business – an optimistic sales forecast that is not matched by adequate production capacity or cash reserves is exactly the kind of tension a strong Paper 1 or Paper 2 answer is expected to identify and discuss.

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 revision checklist

• Identify a case-study business’s market or product orientation before analysing its marketing decisions.
• Connect every marketing objective back to a broader corporate objective.
• Be ready to justify a sampling method choice for a given scenario, not just define sampling types.
• Explain why People, Process and Physical evidence matter especially for service businesses.
• Practise identifying which Unit 4 sub-topic a Paper 1 case study scenario is testing, in combination with content from other units.
