The North Star Metric is a single, company-wide metric that captures the core value customers receive from a product. A product manager uses it to align cross-functional teams, prioritize the product roadmap, and connect daily work to sustainable business growth. It is supported by input metrics that teams directly influence, creating focus and accountability across the organization.
The Opportunity Solution Tree (OST) is a visual framework created by Teresa Torres that helps a product manager map the path from a desired business outcome down through customer opportunities, potential solutions, and validating experiments. It ensures product teams stay outcome-focused, explore multiple solutions before committing, and use evidence from continuous discovery to make better decisions about what to build next.
The RICE framework scores initiatives by Reach (users affected), Impact (how much it moves a metric), Confidence (certainty of estimates), and Effort (work required). Score = (Reach × Impact × Confidence) ÷ Effort. Higher scores mean higher leverage on the roadmap.
