FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The Iterative model is repetition incarnate. Instead of starting with fully known requirements, project teams implement a set of software requirements, then test, evaluate and pinpoint further requirements. A new version of the software is produced with each phase, or iteration.

Detailed explanation-2: -The iterative model is a software development life cycle (SDLC) approach in which initial development work is carried out based on well-stated basic requirements, and successive enhancements are added to this base piece of software through iterations until the final system is built.

Detailed explanation-3: -The iterative process model is a software development life cycle (SDLC) approach in which the initial development work is conducted based on initial requirements that are clearly defined, and subsequent features are added to this base software product through iterations until the final system is completed.

Detailed explanation-4: -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-5: -Spiral. In the spiral methodology, the development process comprises four phases. The developers continually pass through these phases in a spiral, or cycle. After each pass, they progress to a new iteration in development, with the aim of refining the product in each iteration.
