Just like the flow of manufacturing and construction companies, waterfall methodology is a sequential design process. This means that as each of the 6 stages (Requirement Gathering and documentation, design, programming, testing, implementation, and maintenance) are completed, the programmers move on to the development phase of the project.
In this process, once a step has been completed, programmers can’t go back to a previous step – not without scratching the whole project and starting from the beginning. At this phase there is no room for change or error, so a project outcome and an extensive plan must be set in the beginning and then followed carefully.
RevInfotech’s waterfall approach is a well-defined and we follow best practices to deliver your product on time, on budget, and with the required level of quality.
At RevInfotech, each waterfall project is taken through the following four stages: Elaboraton, Implementation, Stabilization and Transition.
The requirements for the software in terms of both design and functionality is captured.
Once the requirements are finalized, a blueprint of the system is drawn to facilitate the process of implementation.
The blue print of the design is verified and the implementation of the system begins according to the blueprint.
The implemented system is now verified and tested by the team. Once the testing is Verification comple, ted reversing the system to and Test implement further changes in requirements cannot be done.

The waterfall methodology is easy to follow and can be implemented for any size of project. It is a linear model with disciplined approach.
With the waterfall methodology, the client knows what to expect. They’ll have an idea of the size, cost, and timeline for the project. They’ll have a definite idea of what their program will do in the end.
In the case of employee turnover, waterfall’s strong documentation allows for minimal project impact. Documentation is produced at every stage of waterfall model allowing people to understand what has been done.
