  1. Chapter 2 Modeling the Process and Life Cycle Shari L. Pfleeger Joanne M. Atlee 4th Edition

  2. 2.2 Software Process ModelsSoftware Life Cycle • When a process involves building a software, the process may be referred to as software life cycle • Requirements analysis and definition • System (architecture) design • Program (detailed/procedural) design • Writing programs (coding/implementation) • Testing: unit, integration, system • System delivery (deployment) • Maintenance

  3. 2.2 Software Process ModelsWaterfall Model (continued)

  4. 2.2 Software Process ModelsSidebar 2.1 Drawbacks of The Waterfall Model • Provides no guidance how to handle changes to products and activities during development (assumes requirements can be frozen) • Views software development as manufacturing process rather than as creative process • There is no iterative activities that lead to creating a final product • Long wait before a final product

  5. 2.2 Software Process ModelsWaterfall Model Most software development processes apply a great many iterations

  6. 2.2 Software Process ModelsWaterfall Model with Prototype

  7. 2.2 Software Process ModelsV Model

  8. 2.2 Software Process ModelsPrototyping Model

  9. 2.2 Software Process ModelsOperational Specificiation Model

  10. 2.2 Software Process ModelsTransformational Model (continued)

  11. 2.2 Software Process ModelsPhased Development: Increments and Iterations

  12. 2.2 Software Process ModelsPhased Development: Increments and Iterations

  13. 2.2 Software Process ModelsSpiral Model

  14. 2.2 Software Process ModelsAgile Methods: Examples of Agile Process • Extreme programming (XP) • Crystal • Scrum • Adaptive software development (ASD)

  15. Pair programming Collective ownership Continuous integration (small increments) Sustainable pace (40 hours/week) On-site customer Coding standard 2.2 Software Process ModelsAgile Methods: Twelve Facets of XP • The planning game (customer defines value) • Small release • Metaphor (common vision, common names) • Simple design • Writing tests first • Refactoring
