The iterative methodology focuses on building insignificant workable feature first and after that over the long run emphasizing this first execution by tweaking and adding extra conceivable outcomes to the feature. Agile then again focuses on building the full feature from the earliest starting point and doing it with short iterations. The iterative procedure starts with a forthright implementation of a subsection of the product requirements and iteratively advancements the progressing alternatives until the full system is affected. At each accent, strategy variations are complete, and new functional capabilities are encompassed. The indispensable thought behind this technique is to build up a system through rehashed cycles iterative and in little portions at time incremental. Iterative and Incremental improvement is a combination of both iterative outline or iterative technique and incremental form model for advancement.
