  • Requirements analysis and definition System and software design Implementation and unit testing Integration and system testing Operation and maintenance The main drawback of the waterfall model is the difficulty of accommodating change after the process is underway. One phase has to be complete before moving onto the next phase.

    15. 15. An Agile View of Process  Represents a reasonable compromise between conventional software engineering for certain classes of software and certain types of software projects  Can deliver successful systems quickly  Stresses continuous communication and collaboration among developers and customers  Embraces a philosophy that encourages:  customer satisfaction,  incremental software delivery,  small project teams (composed of software engineers and stakeholders),  informal methods, and  minimal software engineering work products  Stress on-time delivery of an operational software increment over analysis and design15 IF2036 RPL - IF ITB
    16. 16. Manifesto for Agile Software Development Proposes that it may be better to value:  Individuals and interactions over processes and tools  Working software over comprehensive documentation  Customer collaboration over contract negotiation  Responding to change over following a plan While the items on the right are still important the items on the left are more valuable under this philosophy Note: although most practitioners agree with this philosophy in theory, many pragmatic issues surface in the real world that may cause items on the right to be as important as items on the left 16 IF2036 RPL - IF ITB
    17. 17. 12 Principles  Highest priority: user satisfaction  Welcome changing requirement  Deliver working software frequently  Business people and developers work together daily  Build around motivated individuals  Face-to-face conversation  Working software: primary measure of progress  Promote sustainable development  Continuous attention to technical excellence and good design  Simplicity is essential  Self-organizing team  Tune and adjust team behavior at regular intervals17 IF2036 RPL - IF ITB
    18. 18. Agile Process Models All agile process models conform to the manifesto and the principles Examples:  Extreme Programming (XP)  Adaptive Software Development (ASD)  Dynamic Systems Development Method (DSDM)  Scrum  Crystal  Feature Driven Development (FDD)  Agile Modeling (AM) * SEPA 6th ed, Roger S.
