Choose a representative enquiry and ask the receiving colleague what was missing or misunderstood. Remove personal information and keep the relevant product context. Compare that case with an ordinary complete request. The difference helps identify which instruction, option label or supporting diagram belongs in the interface.
Agree the language for uncertainty. A buyer who has not measured a dimension needs a different response from someone who entered an invalid format. Decide what the business can review in each case and what additional information it will request. Keep any estimate and formal quotation stages explicit so the design represents the intended commercial process.
In Chennai–Ranchi prototype reviews, ask participants to explain the request they believe they have made. Inspect their interpretation alongside keyboard navigation, longer option labels and phone-sized layouts. The handover should retain the approved examples and decisions, allowing the built journey to be assessed against the buyer task rather than its visual appearance alone.
