  1. Ensuring Project Success through an Iterative Development Process by Garth Gullekson

  2. In general • Speaker • Garth Gullekson (ObjecTime) • co-author of Real-Time Object-Oriented Modeling • Presentation • basic, few new (technology) concepts • management oriented • no focus on the ROOM method

  3. Presentation Overview • Software development risk is high • Process addresses this risk • Increments drive progress • Executable models five feedback • Management

  4. Software Development Risk is High • Common problems • requirements: incomplete and inconsistent • complexity • real-time: adds it`s own challenges • distribution • Risk management • major impact of early decisions • feedback only comes later

  5. Process addresses risk • Process views • Waterfall model • Incremental model • For both models: • architecture is the base • Incremental model • continuous feedback -> major defects discovered earlier

  6. Increments drive progress • Which increments should be tackled first? • early critical risk items • ex. tech probe • mid-life heartbeats • deliver results regularly • Thus distinction between • Risk-based increments • Subset-delivery-based increments

  7. Executable models give feedback • Running is the key to getting feedback • requirements, architecture, design should be captured in an executable model • UML applied to Real-Time • capsules • hierarchical decomposition

  8. Management • Project startup • Milestones • Effective team use • Reuse • ...

  9. Conclusion • The presentation was about • using an iterative approach • with executable models • and how to manage this
