What is a modern design approach by which the design and system users use an iterative approach to building the system?
Show 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. When discussing the iterative method, the concept of incremental development will also often be used liberally and interchangeably, which describes the incremental alterations made during the design and implementation of each new iteration. Throughout this article we will take a deeper dive into the iterative model, including where it originated from, how the process is actually implemented within a project, and both the advantages and disadvantages that can arise from its use, so let's get crackin'! Some more specific takes on SDLC include:
Origination and ImplementationsWhile 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. During this period, the United States Air Force and NASA worked together to develop the X-15 hypersonic aircraft, using a largely iterative design process throughout. 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. In the subsequent decades since, iterative methods have been implemented in a wide range of software applications, from modern web applications and high-performance gaming clients, to the United States Department of Defense's software acquisition standard document 5000.2, stating that "There are two approaches, evolutionary and single step [waterfall], to full capability. An evolutionary approach is preferred." The ProcessUnlike 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. Enhancements can quickly be recognized and implemented throughout each iteration, allowing the next iteration to be at least marginally better than the last.
Now the real fun begins! 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. Advantages of the Iterative Model
Disadvantages of the Iterative Model
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 error monitoring software provides real-time error monitoring and automatic exception reporting for all your development projects. Airbrake's state of the art web dashboard ensures you receive round-the-clock status updates on your application's health and error rates. No matter what you're working on, Airbrake easily integrates with all the most popular languages and frameworks. Plus, Airbrake makes it easy to customize exception parameters, while giving you complete control of the active error filter system, so you only gather the errors that matter most. Check out Airbrake's error monitoring software today with a free 14-day trial, and see for yourself why so many of the world's best engineering teams use Airbrake to revolutionize their exception handling practices! What is a modern design approach?Modern design is an interior design style characterized by a monochromatic color palette, clean lines, minimalism, natural materials, and natural light. It refers specifically to a historical aesthetic movement that took place during the early to mid-twentieth century.
What is a sequence of phases in which the output of each phase becomes the input for the next?The oldest of these, and the best known, is the waterfall: a sequence of stages in which the output of each stage becomes the input for the next.
