Chapter 10: Software Development Models Overview

1. Break and Fix:
1. No real planning up front
2. Flaws are reactively dealt with after release with the creation of patches and updates
2. Waterfall:
1. Sequential approach that requires each phase to complete before the next one can begin.
2. Difficult to integrate changes
3. Inflexible model
3. V-model:
1. verification and validation is emphasized at each phase
2. Testing takes place throughout the project, not just at the end
4. Prototyping:
1. A model or sample is created from the code for proof-of-concept purposes
5. Incremental:
1. Multiple development cycles carried out on a pice of software throughout its development stages
2. Each stage provides a usable version of software
6. Spiral:
1. Interactive approach
2. Emphasizes risk analysis per iteration
3. Allows for customer feedback to be integrated through a flexible evolutionary approach
7. Rapid Application Development:
1. combines prototyping an d iterative development procedures with goal of accelerating software development process
8. Agile:
1. Iterative and incremental development processes that encourages team-base collaboration
2. Flexible and adaptive
