Detailed explanation-1: -Agile Model. By breaking the product into cycles, the Agile model quickly delivers a working product and is considered a very realistic development approach. The model produces ongoing releases, each with small, incremental changes from the previous release. At each iteration, the product is tested.

Detailed explanation-2: -Scrum. Scrum is probably the most popular Agile model. The iterations (’sprints’) are usually 2-4 weeks long, and they are preceded with thorough planning and previous sprint assessment. No changes are allowed after the sprint activities have been defined.

Detailed explanation-3: -RAD isn’t designed to work well with smaller projects. It requires automated code-generated tools, making it suitable for projects with minimal development time. Features are often eliminated to fit time limits. Some functions are developed in the later versions to speed up the product’s first release.

Detailed explanation-4: -The Testing and Turnover stage allows for reduced time in the overall testing of the prototypes created. Every model is tested separately to identify and adapt the components quickly to create the most effective product.

Detailed explanation-5: -Agile Model The answer to the question “which SDLC model is the best?” is Agile. The Agile model is a combination of an incremental and iterative approach and is focussed on fitting in well with flexible requirements.

Detailed explanation-6: -What is RAD? Rapid application development is a software development methodology that uses minimal planning in favor of rapid prototyping. A prototype is a working model that is functionally equivalent to a component of the product.
