AGILE MODELING ► A practice-based methodology for effective modeling and documentation of software-based systems ► Agile modeling is not a perspective process

Values ► Communication ► Simplicity ► Feedback ► Courage ► Humility

Principles ► Assume simplicity while modeling ► Embrace changes while you are working as requirements do change over time ► Incrementally change your system to enable agility

Principles  Obtain rapid feedback  Model with a purpose and need multiple models  Content is more important than representation

Practices ► Create several models in parallel ► Apply the right artifacts ► Model in small increments

► Goals of Agile Modeling ► The Scope of Agile Modeling ► It focuses only on effective modeling and documentation.

Test –Driven Development (TDD) Figure 3. Steps of TDD

Comparisions of TDD and AMDD ► TDD shortens the programming feedback loop whereas AMDD shortens the modeling feedback loop. ► TDD provides detailed specification (tests) whereas AMDD can provide traditional specifications (data models). ► TDD “speaks” to programmers whereas AMDD speaks to data professionals

► TDD is non-visually oriented whereas AMDD is visually oriented ► TDD provides concrete evidence that your software works whereas AMDD supports your team, including stakeholders, in working toward a common understanding. ► TDD promotes the development of high-quality code whereas AMDD promotes high-quality communication with your stakeholders and other developers.

Conclusion ► TDD should be seen as complementary to Agile Model- Driven Development (AMDD) approaches and the two can and should be used together ► TDD does not replace traditional testing, instead it defines a proven way to ensure effective unit testing. ► From the design point of view AMDD is different from traditional development approaches but still leads to an effective modeling approach.
