What is Opportunity Solution Tree (Teresa Torres)?

Opportunity Solution Tree (OST) is a visual tool proposed by Teresa Torres for structuring the process of discovering and prioritizing product opportunities.

Main elements of OST:

• Outcome: what you want to achieve (e.g., increase user retention).
• Opportunities: problems or needs of users that can be addressed to achieve the outcome.
• Solutions: specific ideas or features that can realize the opportunities.
• Experiments: ways to test solutions in practice.

OST helps systematically explore which opportunities truly impact the outcome and which solutions should be implemented, minimizing risks and increasing the efficiency of discovery and prioritization.
