Market segmentation

Market segmentation is dividing a market into groups of customers with similar characteristics or needs, so that products and marketing can be targeted.

Common bases:

Benefits: products better meet needs, marketing is more cost-effective, firms can find niches and charge segment-appropriate prices. Drawbacks: research costs, smaller volumes per segment, and the risk of targeting the wrong segment.

Competitive advantage

Competitive advantage is something that allows a business to outperform its rivals, so customers choose it. It comes from:

It must be sustainable: hard for rivals to copy (patents, strong brands, unique locations, skilled staff).

Product differentiation

Product differentiation is making a product distinct from rivals' in the minds of customers, through design, quality, features, brand, service or packaging.

Purpose:

The October 2024 series WBS11 paper asked candidates to discuss the importance of product differentiation (8 marks); the scheme credited quality and innovation as sources and noted cost and price implications as counter-arguments.

Adding value

Added value is the difference between the selling price of a product and the cost of the bought-in materials and components used to make it.

added value = selling price - cost of bought-in inputs

Ways to add value: branding, design, quality, convenience, packaging, customer service, unique features, speed of delivery. Higher added value lets the firm charge more or earn more on each sale, helping to cover other costs (wages, rent) and make a profit. Note added value is not profit: wages and overheads still have to be paid from it.

Worked example

A cafe buys coffee beans, milk and cups costing $0.90 per drink and sells a latte for $3.80. Calculate the added value per drink and suggest one way to increase it.

  1. Added value = 3.80 - 0.90 = $2.90.
  2. Increase it by improving the experience (comfortable seating, latte art, loyalty app) so customers will pay more, or by buying inputs more cheaply without hurting quality.

Answer: $2.90 per drink; raise it through a better experience or cheaper inputs.

Key idea: Segmentation: divide the market into groups (demographic, geographic, psychographic, behavioural). Competitive advantage: lower cost or differentiation. Added value = price - cost of bought-in inputs.

Check yourself

  1. A furniture maker sells a table for $450. The wood, screws and varnish cost $160. Calculate the added value.
    Show answer

    $290. 450 - 160 = $290.

  2. A bakery's added value on a cake is $6.30 and the bought-in ingredients cost $2.70. What is the selling price?
    Show answer

    $9.00. Price = added value + inputs = 6.30 + 2.70 = $9.00.

  3. Dividing customers by lifestyle, values and interests is which type of segmentation?
    • Psychographic
    • Demographic
    • Geographic
    • Behavioural
    Show answer

    Psychographic. Lifestyle and values are psychographic.

  4. Which is a demographic basis for segmentation?
    • Climate
    • Loyalty to a brand
    • Personality
    • Age
    Show answer

    Age. Age is demographic.

  5. Explain one purpose of product differentiation.
    Show answer

    It gives the product a unique selling point so customers see it as different from rivals, which reduces price competition and allows a higher price to be charged.. A USP builds loyalty and allows higher prices.

  6. Which is the best example of a sustainable competitive advantage?
    • A one-week price promotion
    • A temporary shortage at a rival
    • A short advertising campaign
    • A patented design that rivals cannot legally copy
    Show answer

    A patented design that rivals cannot legally copy. Patents make the advantage hard to copy.

  7. Explain one way a hotel could add value to its rooms.
    Show answer

    It could offer excellent customer service and extras such as free breakfast, so guests see the stay as better quality and will pay a higher price.. Added value lets the firm charge more than the cost of inputs.
