What Is Waterfall Model?

Think of yourself as a builder. As with any structure, the base must be laid first, along the walls and the roof. A sequential progression must be followed because one stage depends on the outcome of the prior stage. The Waterfall Model is a good analogy for this. It is common practice in the software industry to use the Waterfall Model, a systematic approach to making a final product. It's a sequential procedure wherein one must finish one stage before beginning the next. The initial step is the preparation stage. Here is where you decide what it is you want to construct and how you will do so. Understanding this is similar to deciphering a house plan. The number of rooms, their intended locations, and the construction materials must be determined beforehand. The design stage follows. Here, you'll use the blueprint as a jumping-off point for the real design. It's the equivalent of choosing the paint for the walls, the carpet for the floors, and the frames for the windows. The third step is the actual doing of it. Here, construction on the house proper begins. It's the stage for the entire construction process, from laying the groundwork to finishing the roof. Phase four involves actual testing. Here, you'll look for problems or flaws in the home. It's the equivalent of taking one last tour of the house before relocating. Finally, we enter the maintenance phase. Whenever something breaks or needs updating, this is where you'll do it. It's like getting an oil change or swapping out the filter on your AC system. #WaterfallModel #SoftwareDevelopment #LinearProcess #Phases #Planning #Design #Implementation #Testing #Maintenance In a nutshell, the Waterfall Model is a method of software development involving a series of stages that must be completed in order. The first step is the planning stage, during which the project's goals and methodology are established. The second stage, "design," involves physical manifestations of the plan. At this point, known as "implementation," you'll begin making tangible progress on the product's development. The fourth stage is testing, where any problems or flaws in the product are looked for and fixed if necessary. When a product's development cycle is complete, it enters a maintenance phase where any bugs are squashed, and updates are implemented.
