in this article, we are going to study one of the software life cycle models, which is the iterative waterfall model. the main drawback in the classical waterfall model was that any sort of error in any of the phases was detected at the end of the entire lifecycle, i.e. so, to overcome this problem, an enhanced version of the classical waterfall model was introduced which was called the iterative waterfall model. what this means is that, in this type of model, the developers are free to go into the previous phases of development to make any sort of modification or changes.
all the phases of the iterative waterfall model are almost the same as they were in the classical waterfall model, and these phases are: each phase of this model is the same as the classical waterfall model. the only advancement that the iterative waterfall model has over classical waterfall model is that in the iterative model, we have feedback paths that link every phase with one another and with the help of those, we can anytime go to the previous phases and make the modifications that may be required in the software in the later phases of the development. & ans. & ans.
in the iterative model, iterative process starts with a simple implementation of a small set of the software requirements and iteratively enhances the evolving versions until the complete system is implemented and ready to be deployed. this process is then repeated, producing a new version of the software at the end of each iteration of the model. iterative process starts with a simple implementation of a subset of the software requirements and iteratively enhances the evolving versions until the full system is implemented. the basic idea behind this method is to develop a system through repeated cycles (iterative) and in smaller portions at a time (incremental). “during software development, more than one iteration of the software development cycle may be in progress at the same time.”
during each iteration, the development module goes through the requirements, design, implementation and testing phases. each subsequent release of the module adds function to the previous release. the key to a successful use of an iterative software development lifecycle is rigorous validation of requirements, and verification & testing of each version of the software against those requirements within each cycle of the model. this model is most often used in the following scenarios − the advantage of this model is that there is a working model of the system at a very early stage of development, which makes it easier to find functional or design flaws. the disadvantage with this sdlc model is that it is applicable only to large and bulky software development projects. this is because it is hard to break a small software system into further small serviceable increments/modules.
the iterative waterfall model provides feedback paths from every phase to its preceding phases, iterative waterfall model is the extension of the waterfall model. this model is almost same as home » software engineering iterative waterfall model (a type of software lifecycle model)., iterative waterfall model vs waterfall model, spiral model in software engineering, spiral model in software engineering.
