So how do you manage large projects or ones with changing requirements? If you use the Waterfall model to manage such projects, you’ll have to restart the development process each time the requirement changes - which is definitely not feasible.Īdditionally, as the testing phase occurs only post-development, you can’t test individual components in such projects - resulting in a bug-ridden product. Large projects are also more prone to changing requirements. You’ll develop a product/system that doesn’t meet Ross’ project requirements correctly!ģ. What happens if you don’t follow this order? To start coding, you need to complete the design phase - only then will you know what programming language and software architecture you need in the development process. Įach phase’s input depends on the previous one’s output.įor example, let’s say you’re developing an Android app for Ross to map dinosaur fossil locations. If you’re using the Waterfall process, you must follow this development cycle in the exact order. If the testing was successful, the finished product is finally delivered to the client or customer. Once you’ve developed the product/system, you verify that it has met the project requirements and works well or not. Testing is the QA stage in a Waterfall project. In software engineering, this phase involves coding the software. In this stage, you develop the project according to the project requirements gathered in the requirements phase. ![]() This includes deciding what technology to use, creating models and diagrams, etc. Once you know what is required, you define the design specifications for the project. This is then documented and analyzed to understand what they want from the projec t. The first step is to gather all project requirements from the clients or customers. ![]() ![]() Let’s find out… The 5 Key Stages in Waterfall Project ManagementĪ project following the Waterfall development methodology ‘flows’ through five key phases: But what are the steps that go into the Waterfall process ?
