Boston Matrix

What is the Boston Matrix?

• A tool to help businesses decide how to manage their portfolio of

  • Businesses

  • Brands

  • Products

• A model which helps analyse a firm’s strategic position

How are products/brands categorised in the Boston Matrix?

• Stars

• Question marks (also known as ‘problem children’)

• Cash cows

• Dogs

What is a relative market share?

• Expressed not as a %, but share in relation to competitors

• Measures the product’s strength in the market

What is market growth?

• % rate of growth of market sales

• A useful measure of market attractiveness, but not the only one

What are features of stars?

• High share of a rapidly growing market (ideally market leadership)

• The product is strong and the market is growing

• Requires high marketing spending

• Cash flow may be positive, depending on profitability and market share

What is the strategy of stars?

• Invest in sustaining growth

• Maintain or build market share

• Repel challenges from competitors

• Create barriers to entry (e.g. branding, customer loyalty, quality advantages)

What are features of question marks (problem children)?

• Low share of a fast-growing market

• Cash flow is usually negative

• Products have potential, but the future is uncertain

• Could become either a star or a dog

What is the strategy of question marks?

• Invest to increase market share

• Try to build a competitive advantage- e.g. through selective market segmentation and positioning

• Build selectly and invest in the most likely stars

• Cash flow likely to be negative

What are cash cows?

• High share of a low-growth market

• Likely to be a mature stage in the product life cycle

• Little potential for growth

• Large, positive cash inflow

What is the strategy of cash cows?

• Defend market share

• Reduce investment in order to maximise cash flow and profits

• Use profits from cash cows to invest in question marks and stars

What are the features of dogs?

• They are usually:

  • Products that have failed or

  • Products that are in the decline phase of their product life cycle

• Low share of a low-growth market

• Not going anywhere and no real potential

What is the strategy of dogs?

• Not worth investing in

• Uses up more management time and resources than can be justified

• Phase out, or sell of

How valuable is the Boston Matrix Model?

• A useful tool for analysing product portfolio decisions

• But only a snapshot of the current position

• Relative market share and market growth are not the only dimensions important to a business

  • Concerned with individual products

  • Focused on sales

• Boston Matrix:

  • Concerned with a portfolio of products, brands and businesses
