Identify the repeated choice
Useful product work begins by observing where people hesitate, reconcile by hand or depend on one colleague’s memory. Those moments reveal the decision a product needs to support.

Recommendations should remain traceable to source facts. That is particularly important when software summarises financial or commercial information: a concise answer is valuable only when a user can inspect how it was reached.
