Quality is delighting customers
As per practices of software testing company, SDLC models which stands for Software Development Life Cycle models. SDLC – is a systematic process, which starts from the beginning of the project, when it’s made a decision to launch the project, and it ends at the end of the product launch.
SDLC aims to produce high-quality software which meets customer expectations. There are multiple SDLC models.
The most used, popular and important SDLC models are given below:
Each process is transparent. In this model, each phase like analysis, projecting, realization, testing, implementation, and support moves Step by Step. In this when on phase gets complete then the new phase will starts. The Main Problem in this model is that requirements should be finalized at an early stage. Otherwise, the whole process may continue in the wrong direction, which could negatively impact the cost of production.
In this model, Full list of requirements before projects does not require. The development may start with the basics requirements, Which can be expanded later. In this model, two modules of a project can be developed parallelly and later we can join these modules.
It's a combination of the Iterative and Waterfall SDLC. In this model, A product has been released in multiples stages as per clients feedback before the final release. As per basic requirements an initial prototype gets is designed and tested. Based on the evaluation of test results, a second prototype is created. Multiples prototypes are constructed to ensure customer satisfaction. The system is created based on the final prototype. The final system is evaluated and tested.
It's an expansion of the waterfall model. In this next stage is started only after the previous phase. Testing and verification take place in the early stages of the project. It's Good for the small projects, where requirements are static and clear.
In Agile after every Release, the customer is able to see the outcomes and understands if he is satisfied with the product or not. In this, a project is divided by shore and transparent iterations.
