WATERFALL MODEL SOFTWARE

WATERFALL MODEL SOFTWARE

Therefore, only if the software is able to be integrated successfully as it was designed will it be able to prove successful down the road. Most new software isnвЂ™t designed to stand alone, but instead to work as part of a bigger overall process. Integration is a key step along the way because it needs to be seen how the new software will work together with any existing software that you may have in place.

This integration will not be on a wide-scale or permanent basis вЂ“ rather, it will be done for the purposes of testing and refining until the software is deemed ready to go. Now that the software is functional, it can be integrated into the system that it is intended to be used with. However, it should be functional and generally in line with the design before it is moved on to the next step within the model. It is important to note that the software will likely not be perfect at this point, and bugs and other issues may still exist. At the end of this phase, there should be a working piece of software that is doing what was outlined during the requirements phase. With a properly created design in hand, the project team can get down to the business of coding what will eventually become the software. This is the phase where the software begins to come to life. Getting one element right before moving on to the next is a key within the Waterfall Model.

If the project requirements were not properly thought out and identified, it will be impossible to correctly design the software at this stage. Of course, since each subsequent step builds on the previous one, they are all vitally important for the project to be a success in the end. Think of this step as building a framework that will then be filled in with the details when the program is actually created. This is done on a higher-level than the actual coding, which will come later. With the requirements for the software sorted out, the next step is to design the basic architecture that will be used.

Once resources begin to be used on the development of the software itself, it will be costly to turn back and make changes to the initial requirements. Software is only useful when it serves the purpose that it was designed for вЂ“ therefore, it is crucial to get the first phase exactly right. What is it supposed to do? What problem is it supposed to solve? These are questions that will likely be asked during this first scoping phase. Getting started toward creating a new software begins by outlining exactly what will be required by the end product. However, the following seven phases are seen in many of the various approaches to this model. As the modelВ has been around for some time, there have been a number of different iterations created through the years. While there are some drawbacks to using the Waterfall Model, it can provide a basic framework for the task of software development. Because of the straight-line approach to development, each department or individual within the process can pass the project down the line when their role in the development is complete. This is a sequential project management method that lends itself nicely to orderly management and delegation of tasks. As the name would indicate, the Waterfall Model is a method of software development in which the progress flows from the top to the bottom.
