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
