A "model" is a representation of something we are trying to understand. Software testers use models so much in their work, we sometimes model software unconsciously. Using different models reveals different kinds of information about the software we are testing. As a result, developing modeling skills, and developing the ability to model software in different ways aids testing. Different testers have their own favorite models and ideas, so sharing knowledge with each other is important.

Testers aren't the only people involved in software development and maintenance who model. Some analysts, architects, database designers, and developers model, some more formally than others. In this session, we will share ideas, and want to hear your ideas on modeling.

How do you model? What sort of models do you develop or use? What kind of modeling tools do you find helpful? Two testers with different backgrounds discuss the types of models they prefer, and some of the modeling tools used in software development. In an experiential segment, we will create a model as a group.
