![]() Here, primarily the development/coding/implementation takes place. Furthermore, some projects can run concurrently within an Agile framework, with fewer dependencies on task completion compared to Waterfall.The architects who are senior members of the team study the requirements and prepare a blueprint for the programmers to work on a schedule for meeting the goals. The product is delivered in the final stage.Īgile allows teams to make changes on the fly when needed, while Waterfall is less adaptable when things go out of process. Waterfall methodology usually involves the customer only at the beginning and end, or at most after each phase. Agile typically has several delivery phases before the final product is finished, and the customer is heavily involved in every stage. The differences between Agile and Waterfall methodologies are subtle yet important. Projects that see great results with Waterfall include: It's great for low-risk, technology-based projects with well-known tools and tech, such as software and app development. The best projects for the Waterfall methodology are clearly defined with understood requirements and definite deadlines. Uncertainty can cause delays or work stoppages.ĭoes not work well when changes occur within a project. Measuring progress within stages may be difficult without time-tracking software.Ĭhanging requirements or unforeseen problems may derail a project, causing delays. Not the best for long-running or complex projects, although agile project management tools can help.ĭeliverables and viable end products may not occur until the very last stage of the project. Great for small budgets and simple projects, but can be expanded as sub-projects of a larger one.Īlthough it's easy to understand and widely used, the Waterfall methodology has some disadvantages: Straightforward time management and tracking.Įasy to arrange tasks within the project scope and goals. Uncomplicated document completion stages and deliverables. Scalable across any type of project or team in your company. ![]() Waterfall methodology offers several benefits with clearly defined deliverables.Įasy to understand from one stage to the next. In our example, websites may need plugins updated in a few months, or new software is released and upgrades become available. You may have to perform maintenance on your deliverable as it evolves and is used. You deliver it to the client, and it's in great shape. Deployment and maintenanceĬongratulations! Your project is ready to go to the customer. Every QA finding is documented so it can be corrected. With a new website build, QA team members look for page load speed, buttons that work, colors aligning correctly, videos loading as they should, and typos in copy. This is your final step before making it live. Once the project is ready to go live, your QA team tests it to see how it's running. For that custom website, a team will need to make a wireframe of the site, add design elements and content, and develop it on a live server. Time-tracking is vital during the implementation phase of Waterfall methodology to ensure everyone stays on task. In this phase, everyone works on dedicated tasks determined from phase one and phase two. Implementation covers the bulk of the project activity. Therefore, your team decides to use a particular content management system (CMS) that supports the high-level user experience needed to achieve these goals. For instance, you determine that the 30-page custom website must load fast, be accessible, and handle many embedded videos for product and service demonstrations. Once the project goals are in place, you'll design the steps and tools you need to get there by developing a Waterfall strategy. For example, your goal might be to create a 30-page custom website in three months. ![]() Teams, including the customer, outline a project's high-level goals and requirements. Waterfall methodology uses five distinct phases that are repeatable for each project on your team. Phases of the Waterfall methodology model That's the metaphor behind the Waterfall methodology. Imagine a stream of water moving from the top of a rocky waterfall, splashing on one ledge after another. Individuals or teams must complete each stage before moving to the next one. The Waterfall methodology or model focuses on the sequential stages of a workflow. ![]()
