CSC532:Term Paper Presentation TOPIC: Agile Modeling Presented By: POLAM SUNITHA.
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.
Agile Model-Driven Development Figure2: The AMDD lifecycle
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.
