Instead of a whole new set of modeling techniques, agile development requires a new way of applying good modeling methods like UML, ER, and UCD, in an incremental, iterative, and evolutionary (Agile) manner. This tutorial introduces an agile software modeling process that strikes the right sufficient-up-front and just-in-time balance. Participants are introduced to a blend of domain modeling, usability modeling, data modeling, and architectural design. We will utilize appropriate UML, ER, and UCD methods in an agile fashion to help limit technical debt, and increase design quality.
