[Re]Shape concept-based prototypes (sketches, mockups, roleplays, etc.) using integrative approaches in order to test the assumptions and benefits of proposed solutions.
Objectives of Process Steps:
1. Identify the risky assumptions and compelling benefits for solution concepts
2. Make prototypes that expose the riskiest assumptions for each solution concept
3. Make prototypes that emphasize the desirable benefits and feasibility challenges for each solution concept
4. Agree on what prototypes to test and the general testing approach
