Tips

Relative market share uses log scale

Bubble size typically represents revenue or profit

10% growth threshold is a guideline, adjust for industry

Consider industry lifecycle - mature industries have different patterns

Don't assume all dogs should be divested - some are strategic

Question marks require quick decisions - invest or exit

Modern capital markets mean cash cows aren't the only funding source

Matrix was created in 1970s - consider if still relevant for your context
