) link multiple traditional systems often suppliedby different software vendors.To manage this, a number of system development life cycle (SDLC) models have beencreated: waterfall, fountain, spiral, build and fix, rapid prototyping, incremental, andsynchronize and stabilize. Although in the academic sense, SDLC can be used to refer tovarious models, SDLC is typically used to refer to a waterfall methodology.
SDLC adheres to important phases that are essential for developers, such as planning,analysis, design, and implementation, and are explained in the section below. There areseveral SDLC Models in existence. The oldest model, that was originally regarded as“the SDLC” is the waterfall model: a sequence of stages in which the output of each stagebecomes the input for the next. These stages generally follow the same basic steps butmany different waterfall methodologies give the steps different names and the number of steps seems to vary between 4 and 7.There is no definitively correct SDLC model, but the steps can be characterized anddivided as follows:
To generate a high-level view of the intended project and determine the goals of theproject. The feasibility study is sometimes used to present the project to uppermanagement in an attempt to gain funding. Projects are typically evaluated in three areasof feasibility: economical, operational, and technical. Furthermore, it is also used as areference to keep the project on track and to evaluate the progress of the MIS team (Post& Anderson, 2006) The MIS is also a complement of those phase. This phase is alsocalled the analysis phase.
Requirements Gatherings And Analysis
The goal of systems analysis is to determine where the problem is in attempt to fix thesystem. This step involves breaking down the system in different pieces and drawingdiagrams to analyze the situation. Analysts project goals, breaking down functions that
