Agile SDLC is usually lead by a scrum Master and is more fast paced than waterfall ( DuPaul). The SDLC process can vary across different businesses and organizations but it involves six stages that establish a lifecycle for software and it is essential to understand what is involved in each step.
The first step in the SDLC is the planning stage. Probably the most important part but this is the stage where all the ideas are laid out. During this phase the objective of the project is determined and the requirements to create the product are discussed.
