Different software development processes are available, including waterfall, iterative, incremental, and agile models. Each process involves careful analysis, design, implementation, testing, documentation, and ongoing support. The choice of process depends on the needs of the project.
The software development process requires careful analysis, specification, architecture design and implementation. Next steps include software testing, documentation, training, and ongoing user support. Different types of computer software development templates are available to help software developers create different computer programs. This development lifecycle involves all the steps from the initial idea or concept of the software to the implementation of the final product. Some of the processes used in computer software development are waterfall, iterative, incremental and agile process models.
As the needs for developing computer software change, so will the methods for developing that software. The key ingredients in developing a software program are determined by the different type of development process used. Most software developers will use some combination or parts of each process in developing computer software.
The first process in computer software development is called the waterfall model. This development model begins by closely examining all potential application software requirements, designing and integrating the actual software, conducting any necessary testing or validation, final installation, and providing ongoing software maintenance. In this computer software development process, each stage must be completed before the next stage is started. Revisions and changes can be used after each stage of development is completed.
The iterative and incremental computer software development process is at the other extreme of the waterfall model software development processes. This process is used by developers when a customer might not know exactly what he needs from a specific computer program. The needs analysis, programming and component development are repeated in short cycles, or iterations, until the final software program is completed. This process uses information gathering and works on a number of smaller components to help bring full functionality to the finished program.
Agile computer software development is less structured than waterfall or iterative/incremental development models. Developing software with the agile development model requires more creativity than structure. In this model, the software is in constant flux, does not follow any logical process and remains incomplete. The people who develop the software and the ways they work together are more important than the actual process. The power of this creative software development process lies in the empowerment and collaboration of the development team, as well as their ability to respond to necessary changes.
