Matt Queen has written an article about Interaction Modeling.
Interaction modeling is a good way to identify and locate usability issues with the use of a tool. Several methods exist (see Olson & Olson 1990 for a review of techniques). Modeling techniques are prescriptive in that they aim to capture what users will likely do, and not descriptive of what users actually did.

This article presents a three-part method of interaction modeling where:
- A prescriptive, preferred interaction model (PIM) is created
- A descriptive user-interaction model (UIM) derived from an actual user study session is created
- A model of problem solving and decision making (PDM) is used to interpret disparities between the first two models
It is a great article about interaction modelling.
