Product-oriented processes are needed to define and create a product, service, or information system. These processes will define how the systems development life cycle (SDLC) will be implemented. Subsequently, this will define all of the sub-phases and deliverables associated with the Execute and Control project management life cycle phase.
There are a number of ways to implement the SDLC. The chosen method or approach depends on the size and complexity of the project, as well as the experience and skills of the project team. A particular method will not only define the software processes and tools needed, but will also be a critical factor for developing the project plan in terms of defining project phases, deliverables, tasks, and resources that will be used to estimate the project's schedule and budget. Today, an IT project will follow a structured development approach or an iterative development approach.
