  1. Basic SDLC Models SDLC  System Development Life Cycle. Why models? Due to the complexity of software systems. Model examples Waterfall model Spiral model RUP (Rational Unified Process) model Agile models CIS 487

  2. Waterfall Model CIS 487

  3. Spiral Model CIS 487

  4. RUP Model CIS 487

  5. Agile Models Important example - Extreme Programming (XP). Currently the best-known and most widely used agile method. XP takes an “extreme” approach to iterative development. New versions may be built several times per day. Increments are delivered to customers every 1 - 2 weeks. All tests must be run for every build and the build is only accepted if tests run successfully. CIS 487

  6. “Simplified RUP” Business analysis Requirements Analysis. Logical design – process and data. Design. Interaction, data, and architecture. Implementation and testing. Deployment and maintenance. Use appropriate tools such as UML diagrams. CIS 487
