Lessons From the Field: Solving Abstraction

Overview

One of the most difficult concepts in the modelling use cases is the exact level of detail (often called level of abstraction) to model to. Some modellers may model at a very high level of abstraction which implies that the use case can still be broken down into several more detailed use cases. Other modellers prefer to model at a very detailed level of abstraction which means that they prefer to work at a very detailed use case level that often cannot be broken down any further. As long as one modeller develops and maintains a model this does not have too many drawbacks.
