Ask for the product truth
The Jobs-style question is simple: what should the user feel in the first minute, and what can be removed until that feeling is obvious?
Use taste as a filter
A product strategy roundtable should expose vague features, weak defaults, and language that sounds internal instead of human.
Pair design with engineering reality
Bring Jony Ive for care and Karpathy for reliability. The result is sharper than a single product critique.
