The waterfall model is considered the most traditional software development method. Also known as the linear-sequential life cycle model, this SDLC methodology remains a useful approach for projects with fixed and clear requirements.

It's a useful model when you don't want to be involved in the development process. Simply provide your requirements, and we'll deliver the finished software product, along with maintenance support. The best part is, with this model, we can determine your cost estimates before the project begins.

Symphony Software works with this model on projects that have to be completed to a predefined quality against a deadline at a given cost.

Here’s how we do it:
Different Stages of SDLC Waterfall Model

Your project goes through all phases of the waterfall model. Deliverables from one phase feed to the next stage. So, we can't move on to the next stage before the previous one has been completed.

Stage 1: Requirement Analysis
Our team captures all your requirements. We brainstorm and analyze these requirements to ensure that the project is testable and feasible or not. Outcomes of the analysis phase should be the requirements understanding document (RUD).

Stage 2: System Design
Senior project members and architects create the design and figure out the hardware/software requirements. Finally, our team documents the entire design for the project. The architect creates a high-level design document (HLD) and a low-level design document (LLD) for the next phase.

Stage 3: Implementation (Coding Phase)
As per HLD and LLD documents, programmers write the software code making sure that all requirements are laid out. At this stage, testers perform unit testing of the code. Deliverables include coded programs and unit test cases with results.

Stage 4: System Testing
In this phase, our testing team tests the software to confirm if the system meets all specifications provided by the client. Testers identify and report issues and bugs within the application.
