Linking high level models and implementation models

Sound conceptual models may help the organization to reconsider the way it sees itself, and this can be worthwhile. But can conceptual models help us with the implementation of IT systems?

One consultant I worked with believed there was no need to have any links between a conceptual model and implementation. He resisted any attempt by others to do so, arguing that such activity would only distract the conceptual thinkers from their work. His conceptual models had one-to-one associations all over the place that did not reflect reality, but he didn't care, because it was "only conceptual". Similarly, he didn't care if there was confusion between entities that represented types versus instances – to him, such considerations were mere implementation details. Nor did he want to provide useful descriptions for his conceptual entities (the description for the Action Type entity was "A type of action"), and he fought against requests to include real-world examples in his textual description of entities. Perhaps, not surprisingly, he frequently refused to provide any attributes that might throw some light on the intent of his entities.
