Software development models

The software engineering process chosen by the developing team will determine how much internal documentation if any is necessary. Early involvement of developers. If, on the other hand, the problem is unique at least to the development team and the structure of the software solution cannot be easily envisioned, then a more "extreme" incremental approach may work best.

What are the Software Development Models?

Testing and debugging during smaller iteration is easy. In practice, however, the model is rarely used. The usage It is used in the large applications and systems which built-in small Software development models or segments.

Deployment and maintenance[ edit ] Deployment starts directly after the code is appropriately tested, approved for releaseand sold or otherwise distributed into a production environment. Integration tests are performed to test the coexistence and communication of the internal modules within the system.

This is a highly-disciplined model and the next phase starts only after completion of the previous phase. Process and results are well documented. Manages risks and develops the system into phases. These unit tests can be designed at this stage based on the internal module designs.

A variety of such frameworks have evolved over the years, each with its own recognized strengths and weaknesses. The risks might be due to cost, schedule, performance, user interfaces, etc. In addition, the costs for for training the development team on prototyping may be high. Iterative Development Iterative development model aims to develop a system through building small portions of all the features, across all components.

Prototypes that are eventually discarded rather than becoming a part of the finally delivered software Evolutionary prototyping: We deliver the system into the production operating environment. These activities may involve the development of the software from the scratch, or, modifying an existing system.
