![]() MaintenanceĪfter the deployment process, some issues come up on the client-side. Once the functional and non-functional testing is complete the project is deployed in the market or the customer environment. After the integration process, the entire system is processed for any faults or failures. The units developed in the Implementation phase are tested and then integrated into a system. These units are tested for their functionality, and this is referred to as the unit testing. The input from the system design phase is used to develop a system in small programs or units. The model helps in preparing the overall system architecture. System DesignĪfter the requirements have been specified, those requirements are studied, and system design is created. The first phase includes understanding the project requirements to be developed and documenting those requirements. The Waterfall Model approach is divided into six phases. The top-down approach of the Waterfall Model is called the Linear-Sequential Life Cycle Model. ![]() The process starts with the step of gathering requirements and goes up to the maintenance step. All those phases are followed in the Waterfall Model in a top-down approach. The project is broken down into several sequential phases. More importantly, the next step depends on the deliverables of the previous step. The model is a collection of several phases, and each phase needs to be complete for the next phase to begin. The Waterfall Methodology is the earliest Software Development Life Cycle approach to software development. The two most famous and popular SDLC models are: Every process has its series of steps that ensures its success. Several Software Development Life Cycle Models are followed for successful software development processes. ![]() The project is completed within the required time frame and estimated cost. The software development process makes sure that customer satisfaction is achieved. The process defines tasks that have to be performed at each step in the software development process. The SDLC aims to create the best quality software keeping in mind the customer’s expectations and deadlines. Software Development Life Cycle (SDLC) is the process of designing, developing, and testing high-quality software. Hence, this article will help you choose a better fit for your requirement. Here, we shall see the comparison between the two, Agile Vs. While finalizing the models to take up, the two most prominent models are the Waterfall Methodology and the Agile Methodology. The first and foremost decision to be made while building software is to finalize which development methodology to consider.
