System development life Cyc - Essay Example

System development life Cycle Systems development life cycle is a conceptual model used in project management and thus describes the various stages involved in an information system development project, from an initial feasibility study through maintenance of the completed application.Systems development life cycle is important as it helps business organization facing a keen competition in the market, thus ensuring rapid change of technology and fast internal demand, as the system development is necessary in helping to fast-track the competition.

During the system development, a business organization could adopt the systematic method for such development to help them face out rising competition. Most popular system development method is system development life cycle (SDLC) which supports the business priorities of the organization, solves the identified problem, and fits within the existing organizational structure. System development life cycle is important in developing IT projects, describing the different stages involved in the project designed from the initial stage to its completion.

There are various models in the system development life cycle that include; Waterfall model, Iteration model, V-shaped model, Spiral model, and Extreme model that play a great role in software processes. (McGonigle & Mastrian, 2011)The various models have similarities and differences in their functioning. It is noted that the model are all vital in developing systems for different sizes of projects and the various requirements to be achieved in the different projects. Waterfall model and spiral model are the most commonly used models for developing of the systems.

Each model has advantages and disadvantages for the development of the systems, thus each model tries to eliminate the disadvantages of the previous model. The Waterfall model is the oldest, thus the models are progressive from the Waterfall model to the extreme model as they get to improve their systems from one model to the other.
