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 model is a particular implementation of a software development life cycle (sdlc) that focuses on an initial, simplified implementation, which then progressively gains more complexity and a broader feature set until the final system is complete. while agile development models such as the iterative model have come to be a generally accepted evolution over the traditional waterfall model of the past, it turns out that iterative methods were used in projects as early as the 1950s. while this wasn’t directly a software development project, the success of this process led nasa to use an iterative model for the software development of project mercury, which was the first manned spaceflight for the united states. an evolutionary approach is preferred.” unlike the more traditional waterfall model, which focuses on a stringent step-by-step process of development stages, the iterative model is best thought of as a cyclical process. after an initial planning phase, a small handful of stages are repeated over and over, with each completion of the cycle incrementally improving and iterating on the software.
this is the crux of the entire iterative model, whereby the most recently built iteration of the software, as well as all feedback from the evaluation process, is brought back to the planning & development stage at the top of the list, and the process repeats itself all over again. with the adept agility and rapid turnaround of iterative model projects, you need an exception management tool that can keep up the pace, without the overhead of user-intervention. airbrake’s state of the art web dashboard ensures you receive round-the-clock status updates on your application’s health and error rates. check out airbrake’s error monitoring software today and see for yourself why so many of the world’s best engineering teams use airbrake to revolutionize their exception handling practices! discover the power of airbrake by starting a free 30-day trial of airbrake.
