What is Agile Modeling?

Agile Modeling

• The purpose of modeling (sketching UML, …) is primarily to understand, not to
• document.
• It implies a number of practices and values, including:

1. – Adopting an agile method does not mean avoiding any modeling. Many agile methods, such as Feature-Driven Development, Dynamic systems development method (DSDM), and Scrum, normally include significant modeling sessions.
2. – The purpose of modeling and models is primarily to support understanding and communication, not documentation
3. – Don’t model or apply the UML to all or most of the software design.
4. – Use the simplest tool possible
5. – Don’t model alone, model in pairs (or triads)
6. – Create models in parallel.
7. – Know that all models will be inaccurate, and the final code or design different sometimes dramatically different—then the model. Only tested code demonstrates the  true design
8. – Use “good enough” simple notation
9. – Developers themselves should do the OO design modeling
