SIE.3:2 - Problem

Available models often look adequate because their terms resemble the receiving question. A field named inspection may cover a plan, a requirement, an occurrence, or a result. Mapping every such field to one class can remove exactly the distinction the receiver needs.

The opposite failure is to construct a larger ontology whenever a model question arises. That incurs design and maintenance work even when an existing model can answer the question. Both failures begin before formalization: the required meaning and its useful boundary have not been established.
