BCG Matrix
Plot business units or products by market growth and relative market share, interpret Stars, Cash Cows, Question Marks and Dogs, then explore how investment allocation and market changes affect the portfolio.
Use market growth and relative market share to make the portfolio structure visible.
The BCG Matrix positions business units or products according to two variables: market growth and relative market share. It provides a simple portfolio lens for discussing where investment, cash generation, selective growth or rationalisation may deserve management attention.
The guided demonstration uses fictional data, direct manipulation and a market-change challenge to show why the matrix should be treated as a strategic conversation tool rather than an automatic investment rule.
BCG Matrix — Step by Step
Eight locked stages move from portfolio context through market growth, relative market share, quadrant classification and investment logic, then apply a market-change challenge and conclude with management review.
Market Growth, Relative Market Share and Portfolio Position
Reveal the portfolio context to begin.
Trace each business unit from portfolio data to quadrant and management implication.
Test a Single Business Unit
Experiment Mode is isolated from the guided demonstration. Change market growth, relative market share and revenue scale to observe the resulting BCG position.
Test BCG Matrix judgement.
BCG Matrix decision cues
Star
High market growth and high relative market share. Often requires investment to defend leadership and can become a future Cash Cow as growth slows.
Cash Cow
Low market growth and high relative market share. Often associated with strong cash generation, but the business still needs enough investment to protect competitiveness.
Question Mark
High market growth and low relative market share. Requires selective investment decisions because growth potential may be attractive but leadership is not established.
Dog
Low market growth and low relative market share. May be a candidate for harvesting or divestment, but strategic fit, profitability or ecosystem value can justify continued participation.
Relative Market Share
Typically compares the unit’s market share with that of the largest competitor. A ratio above 1.0 indicates the unit is larger than the leading rival used as the reference.
Management Cue
Do not make automatic investment decisions from quadrant labels alone. Test profitability, synergies, strategic fit, risk, market definition and future economics.
Use market growth and relative market share consistently, test the assumptions behind the boundaries, and combine the matrix with profitability, strategic fit, capability and risk analysis before allocating capital.
