If you prefer Waterfall method, we are open to use classic Waterfall approach. At starting, we'll analyze your requirements in very details using different requirement engineering techniques. Based on the requirements, we'll prepare comprehensive SRS with scope of work, context diagram, use cases, actor diagram and detail functional requirements.
For fixed price contract, we follow waterfall methods and agile principles. We are expert in every phase of waterfall methods and SDLC with standard and on-demand documentations.
There are few criticism against waterfall methods. For example, Clients may not know exactly what their requirements are before they see working software and so change their requirements, leading to redesign, redevelopment, and retesting, and increased costs. Despite the criticism and the development of new software engineering models, the Waterfall method is still the dominant process model.
If you would like to choose waterfall models to build your software, we’ll serve the best practices and bring successes. For fixed price contract, we can follow waterfall methods if requirements are fully specified. We are expert in every phase of waterfall methods and SDLC with standard and on-demand documentations. The requirement engineering stage usually costs about 10% of the total project price and lasts from a couple of days up to 5 weeks for big projects. What is more important, it saves time and up to 50% of costs during implementation stage.
