Start with an answerable question
What decision will the model support? Comparing design options needs different information from reviewing quantities or preparing operational data. Write down the intended use, then translate it into outputs the team can deliver and check.
Make the requirement explicit
Try a simple register: required information, purpose, responsible producer, delivery date, and verification method. For a door review, for example, identify the zone, door identifier, required property, and reference used to check it.
Test a small scope
Choose one zone and a known model revision. Request a sample deliverable and check completeness and usability before extending the requirements. Record ambiguities, revise the instructions, and repeat the sample.

A practical output this week
Create a five-column information register for your next delivery. Review it with both producer and recipient. A useful trial ends with a shared understanding of what will be delivered and how it will be accepted.
