Green and Benyon (1996) describe a method called ERMIA (entityrelationship modelling of information artefacts) that enables such discrepancies to be revealed.

ERMIA models structural knowledge and so can be used to represent the concepts that people have in their minds.

Relationships between the entities are annotated with 1 or m, indicating whether an entity instance is associated with one or many instances of the other entity.

ERMIA uses an adaptation of entityrelationship modeling to describe structures.

An important part of this type of analysis is that it helps to expose differences between the designers model, the system image and the users model.
