![]() ![]() Once the end goal is established, Waterfall does not involve the client or project owner during the process, apart from specific check-ins or for deliverables. The Agile Manifesto, an online document released in 2001 by a group of software developers, says team members are expected to, “Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.” Rather than a fixed timeline, the schedule adapts as the project progresses. The idea is that the start and finish of the project are already mapped out from the beginning.Īgile is a lot more flexible and accounts for experimenting with different directions. The expectations for the project and the deliverables of each stage are clear and are required in order to progress to the next phase. Waterfall methodology is a linear form of project management ideal for projects where the end result is clearly established from the beginning of the project. Requires: Completing deliverables to progress to the next phase.Approach: Hands-off goals and outcome established from the beginning.The project timeline is more difficult to determine from the start, and it is also more susceptible to change The methodology is client-facing, which means that the team shares progress and incorporates feedback into the process It also means that work can get lost or miscommunicated between team members, especially when people leave and join the team in the middle of the projects. It can be harder to ensure the entire team is on the same page-especially if it’s a large team with different departments. There is a lot of flexibility to change project direction and experiment with new directionsĭeliverables are not a requirement to progress to the following phase. The system must be properly maintained and receive proper attention to keep it running smoothly.Short-term deadlines encourage productivity and efficiencyīecause team members are working on multiple phases at a time, there is potential for overlap or unnecessary effort spent on later stages if an early phase needs to be modified ![]() MaintenanceĮven if the product has been thoroughly tested, some problems may crop up once the product is available to a general audience. Other times, the product may be released as a final product, completely ready for market. Sometimes, this may be in the form of a beta product that can then be tested in a customer-facing environment. Once the product has been thoroughly tested, it will be released to the market. Once all of the units have been tested individually, the project as a whole is tested to determine its continuing effectiveness and make sure there aren't any unforeseen challenges. Integration and TestingĮach unit is integrated into the system. By putting them together as individual units, it's possible to separate out problems and get a better feel for how the project is functioning. ImplementationĮach section of the design, known as "units," are put together as part of the total system and tested to see their efficiency and effectiveness. The team will put together the broad design of the system based on the initial requirements discovered during the analysis phase. These specifications will be clearly documented. ![]() In the first step, the team gathers all the requirements for the project and analyzes what it will take in order to complete it. ![]()
