| Criterion |  Product Discovery Pretotyping |  Architecture ARID (Active Reviews for Intermediate Designs) |  Innovation Brainstorming |
|---|---|---|---|
Purposedifferent | Pretotyping clarifies whether a customer problem and solution idea create enough real demand. It separates problem, assumption, solution, and evidence, and captures the result as a pretotyping sketch, test setup, and conversion data. | ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification. | When a team faces an open question with many obvious directions, the method first creates breadth instead of premature commitment. It separates idea flow from evaluation and makes lines of thought visible, creating a pool for selection and further development. |
