Producing Adequate Definitions

We know how important definitions are, yet we also know that definitions are often missing or of poor quality in data deliverables. Over the years I have used a number of techniques to ensure adequate definitions are present. For example, one technique is to write the attribute definition before naming the attribute. This not only guarantees you’ll have a definition, but you will also often come up with a better attribute name. What techniques do you use to produce adequate entity and attribute definitions?
