![]() DSDM (Dynamic Systems Development Method), FDD (Feature-Driven Development), XP (Extreme Programming) and, probably the most popular, Scrum, all draw from Agile to execute software development processes. Each iteration adds value to the product and provides working software as it concludes, planning the nearest step in more detail than the others that will follow.ĭifferent subsets adopt Agile as a philosophy, similar to what happened with the variations of Waterfall. That is where it differs the most from the Waterfall method.Īgile seeks to be more flexible, allowing regular increments and minimizing the time needed for planning by focusing on shorter timeboxes. The various cycles - conventionally named sprints - seek to cumulatively deliver value, being part of a bigger picture that leads to project completion. This very straightforward document, put together by a group of developers in Utah, surely broke the conventions and limitations of software development, providing a real alternative to the Waterfall method.Ībove stands a perfect example of what Agile aims to be. Still, it was only in 2001 with the Manifesto for Agile Software Development, that Agile software development (as we know) was introduced and popularized. The principles of incremental software development were already being used through different scattered processes. ![]() What caused it? Agile software development. While the Waterfall model was far from being the only possible approach to software development, it was not until 2001 that it experienced a fundamental paradigm shift. Additionally, it is possible to estimate the whole project's cost and effort needed right from the start in the requirements phase through this model. The reason? To avoid starting development before the design work is completed, which could give way to possible incongruities in both ends. Waterfall ensures that each phase is completed before moving on to the next one. ![]() It contemplates all the essential points that compose software development, and its simplicity made it very easy to understand and adopt immediately. When a phase is completed, its output becomes the input for the next one, which starts immediately after the former. Some variations of the original model emerged in the following decades, but the logic behind Waterfall remained the same. It was published in 1970 by the computer scientist Winston Walker Royce, and it originally contemplated five distinct phases: requirements, design, implementation, verification and maintenance. The Waterfall methodology was named after its sequential phases arranged in a downward fashion (similar to actual waterfalls), representing the various steps of software development from one end to the other. Waterfall vs Agile: does Agile represent the end of Waterfall?.All things considered, it will be also explained why at Imaginary Cloud we've decided for Agile instead of Waterfall in our development process. Starting from the very basics, we will clear the current state of both methodologies in software development, answering some of the most common questions regarding each. Is Waterfall dead? Did Agile definitely take its place? Is one better than the other? ![]() Waterfall came first, Agile appeared more recently, but we're far from reaching a consensus about which better suits development needs. When it comes to software development, there's always that million-dollar question: which methodology to use, Waterfall or Agile? Everyone has an opinion about it, and often, preferring one methodology means disregarding the other as a valid option. ![]()
