Introduction to marketing

· Marketing = the business function focused on identifying, anticipating and satisfying customer needs profitably. For this topic, focus on how firms choose between product orientation and market orientation, and how they measure performance using market share and market growth.
· Exam focus: define the term, calculate simple percentages when given data, and explain why these indicators matter for competitiveness, strategy and leadership in a market.

Market orientation versus product orientation

· Market orientation = a business starts with customer needs/wants, then designs or adapts products to meet them.
· Product orientation = a business focuses first on the product itself, especially quality, design, technical excellence or what the business believes it can make well.
· A market-oriented firm is usually more responsive to changes in consumer preferences, competition and market trends.
· A product-oriented firm may succeed when customers value craftsmanship, innovation, heritage or a highly distinctive product.
· Simple contrast: market-oriented businesses make what customers want; product-oriented businesses try to sell what they make best.
· Exam tip: avoid saying one is always better. The best approach depends on the industry, customer expectations, competition and the firm’s brand positioning.
· In evaluation, a market orientation often reduces the risk of producing goods customers do not want, but product orientation can create strong differentiation and brand identity.

This image introduces market orientation as a customer-focused approach. It is useful for reminding yourself that the business starts with consumer needs rather than with the product. Use it to anchor the contrast with product orientation in exam answers. Source

Market share

· Market share = the percentage of total sales in a market earned by one business over a given time period.
· Formula: Market share = $\frac{\text{firm's sales}}{\text{total market sales}} \times 100$
· Always use the same time period and the same market definition when calculating.
· A business with rising market share is usually becoming more competitive relative to rivals.
· A business can increase market share by improving quality, lowering price, strengthening promotion, innovating, or acquiring competitors.
· High market share can bring economies of scale, stronger brand recognition, better bargaining power with suppliers and distributors, and more influence over the market.
· But do not assume high market share always means high profit: a firm may gain share through heavy promotion or low prices, which can reduce margins.
· Exam technique: if asked to interpret data, comment on both the size of the share and the trend over time.

This image shows the core market share formula and is useful for calculation questions. It helps connect the concept to data-response tasks where you must compute or interpret a firm’s share of total market sales. It is best used alongside a simple worked example. Source

This chart is a real example of market share shown visually over time. It helps you see that market share is not just a single percentage; it can be tracked to show whether a firm is gaining or losing position against competitors. In exams, that kind of trend supports stronger analysis than quoting one figure alone. Source

Market growth

· Market growth = the increase in total market size over time. It shows whether the whole market is expanding, stagnant or shrinking.
· Formula: Market growth = $\frac{\text{new market size} - \text{old market size}}{\text{old market size}} \times 100$
· A market can grow because of higher consumer incomes, population changes, new technology, changing tastes, stronger promotion across the industry, or expansion into new regions.
· In a high-growth market, firms may find it easier to increase sales because overall demand is rising.
· In a low-growth or declining market, competition is often tougher because firms must take customers from rivals to grow.
· Exam tip: distinguish market growth from sales growth. A business’s sales may rise even if the market grows faster and its market share falls.
· Strong answers often compare both figures: sales growth vs market growth. This shows whether the firm is outperforming or underperforming the market.

This diagram links market growth with relative market share on one visual. Even though it is a strategy tool, it is excellent for 4.1 because it shows how businesses interpret both indicators together when judging competitive position. It also helps explain why growth matters differently depending on whether a firm already holds a strong share. Source

Using market share and market growth together

· Market share tells you a firm’s position relative to competitors.
· Market growth tells you how attractive or fast-changing the whole market is.
· A business in a high-share, high-growth market may have strong future potential but may still need heavy investment to maintain its position.
· A business in a low-share, low-growth market is in a weaker strategic position and may face limited opportunities.
· In exams, combine both indicators before making a judgement. Looking at only one can give a misleading conclusion.
· Strong evaluation language: “This suggests… however… because…”

This is one of the clearest diagrams for understanding the relationship between market share and market growth. It shows why firms with the same sales figure can face very different strategic situations depending on how fast the market is growing. It is especially useful for HL students when discussing leadership and competitive strength. Source

Common exam traps

· Do not confuse market share with revenue: a firm can have high revenue in a very large market but still a modest market share.
· Do not confuse market growth with a firm’s own sales growth.
· Do not assume product orientation means ignoring customers completely; it means the product is the starting point.
· Do not assume market leadership always means the highest profitability.
· In AO3/AO4 questions, always support judgement with data, context and a brief balance/limitation.
