We've compared the Agile model to the traditional project management model . Here's a summary of the key differences between the Agile SDLC and the Waterfall SDLC .
The Six Phases of the Agile Software Development Life Cycle (SDLC)
Although the Agile software development life cycle (SDLC) is extremely flexible, it still breaks down into six fundamental phases: planning, development, testing, deployment, maintenance, and retirement.
Phase 1 of the Agile SDLC: Planning
The planning (or design) phase of the Agile SDLC defines bulgaria phone number lead the vision and objectives of the project. At this stage, a product roadmap is created . Next, competing products are studied and the features needed for the project are prioritized. This is also the time to estimate the costs and resources required to complete the entire project.
Phase 2 of the Agile SDLC: Development
During the Agile SDLC development phase, developers work together in successive sprints to create a product that meets the requirements defined during the planning phase. The goal isn't to achieve perfection, but to create a solid foundation from which to build the final product.
Phase 3 of the Agile SDLC: Testing
Starting with the preliminary product release, regular testing begins to ensure each update works as expected. The results of each test are documented and any bugs are fixed before moving on to the next stage of the Agile SDLC.
Phase 4 of the Agile SDLC: Deployment
After much back-and-forth testing, the finished product is finally approved when it's deemed ready for market launch. However, in Agile cycles, it's common to conduct a soft launch or beta test with a pilot group before launching the product to a wider audience.
