Knowing your nouns, having added business definitions to them, after adding verbs to relationships, the only test left is this: "Does it apply to other contexts?"

Sometimes the collection of words only apply to a specific context, while a slightly other context with a different set of constraints, make your definition invalid. Just imaging the examples of inventory. Inventory could be loosely defined by the amount of products available in the store. But only when counting the actual amount, do we realize the numbers are off. Different departments express different numbers. The purchase department added the amount ordered; the sales department subtracted the amount preordered; whereas the warehouse staff only counted the physical items.

So, nouns and verbs matter, but as context shows, there's more out there to know before we can be really sure about the data we so easily use and apply.
