SDLC Iterative model

SDLC Iterative model

In this model of software development life cycle, the iterative method begins with a simple execution of the small group of the requirements. sdlc

Iteratively the versions enhanced until we have a complete system that is all set to implement and deploy. sdlc

An iterative life cycle model doesn’t begin with a complete set of requirements by the client, so it is easier to use. sdlc

The development process starts by listing the requirements and executing only part of the program or system, which assessed to recognize the further needs of the software.sdlc

A model that is more suitable for changing needs and bigger products is the Iterative Model. sdlc

This one differs from the previously mentioned models by focusing on subsets of the software after the requirements stage and up to the release. sdlc

This allows user feedback, a greater ability to find issues during development, and an easier time fixing those issues. sdlc

Because the software is being built piece by piece, it does take longer and require higher levels of resources. sdlc

It all has to work together and without the skills to accomplish that it would be disastrous. sdlc

It essentially requires rewriting the software each time, with more added to it and fixes worked in. sdlc

One big benefit is that with each version of the software completed, it gives the customer and users a product they can use, satisfying their needs at a quicker pace while still improving the product. sdlc

However, this can also open the product to issues in the overall outcome.

As mentioned previously, it takes a great deal of skill to make sure all the pieces fit together, and even the most skilled may run into an unforeseen problem once all the subsets are finalized. sdlc

In the iterative model, modifications made in the system design and some new features during each iteration. sdlc

This process continues until complete software is ready according to the client’s requirements. sdlc

Applications using Iterative Model sdlc

The iterative model used when: sdlc

• The system requirements defined and understood clearly. sdlc
• The development project is vast.  sdlc
• The main requirements of the software or system must be well-defined; though,  sdlcsome minor details could add with time. sdlc

Why should you use Iterative Model? sdlc

• We can easily measure the progress of the project. sdlc
• Testing and troubleshooting during smaller iteration is easy. sdlc
• Planning of parallel development sdlc
• It is readily acceptable to the ever-changing needs of the project. sdlc
• Risks recognized and resolved during the iteration.   sdlc
