System development life cycle, Waterfall model, steps, advantages and disadvantages  

i)

Essentially, systems development is the process of defining, designing, testing, and implementing a new software application or program (Ma, et al., 2018). It could include the internal development of customized systems, the creation of database systems, or the acquisition of third party developed software.

The system development life cycle (SDLC) serves as a process applied to create systems/software products (Alenezi and Almuairfi, 2019). SDLC covers several steps and is also sometimes referred to as the “application development life-cycle.” Typically, it begins with the organization’s decision to create an information system and finishes with continuous support. In this case, it starts with the decision that a small systems be developed for the department and ends with deployment and maintenance of the system.  There are various software development life cycle models defined and designed which are followed during the software development process (Ahmad and Wong, 2018).  The popular SDLC models followed in the industry include; waterfall Model, Iterative Model, Spiral Model, V-Model and Big Bang Model.
