Always translate feature requests into problems. "They want an export button" might really mean "they need to share data with finance" - which might have a better solution.
Best answers: thank sales for the intelligence, dig into the underlying problem (not just the requested solution), assess whether the requests align with product strategy, check if other customers share the need, evaluate the revenue opportunity against the development cost, and communicate the decision back with rationale.
Critical B2B PM skill. Candidates who build everything sales asks for create Frankenstein products. Those who ignore sales lose deals. The balance is translating requests into validated needs.
