| Criterion |  Innovation Design Sprint |  Product Discovery Test Card |  Innovation Design Thinking |  Product Discovery Learning Card |
|---|---|---|---|---|
Purposedifferent | When the product question is unclear and time pressure is high, the method takes a team from an open idea to a testable solution. It connects problem understanding, decision, and learning in one compact format, lowering the risk of spending a lot of energy on a mere guess. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | For complex user problems with an uncertain cause, the method connects observation, interpretation, and experiment into a learning cycle. It keeps the focus on real needs and avoids premature solution language. This produces robust decisions for product and service. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
