Structure a portfolio discussion using relative market share and market growth while exposing the limitations of simplified labels.
Core components
- Stars
- Cash cows

Copy-ready prompt
Create a BCG-style portfolio analysis for [business units or products]. Use supplied data for relative share and market growth, show calculations, mark missing evidence, and do not force uncertain items into a quadrant. Recommend invest, maintain, harvest or investigate actions with assumptions and risks.
Three practical uses
- Review product portfolios
- Discuss investment allocation
- Identify missing evidence
How to improve the output
Replace every bracketed variable with decision-specific context. Supply source material, dates, geography, constraints and definitions. Ask the assistant to label assumptions and uncertainty. Verify factual claims against primary sources and let an accountable person challenge the recommendation before action.
Responsible AI use: do not enter confidential, personal or regulated information unless your organization has approved the tool and data controls. AI output can be incomplete, biased or wrong.
Learn the management logic behind the prompt
A prompt is more useful when the person reviewing the output understands the framework, evidence and trade-offs.
