Systems Development Life Cycle Sdlc Phases
An increase in demand for software to meet customer needs effectively but with less cost and faster delivery has put tremendous pressure on modern organizations.
Systems development life cycle sdlc phases. Each phase produces deliverables required by the next phase in the life cycle. Software development life cycle models 1 waterfall model 2 v shaped model 3 prototype model 4 spiral model 5 iterative incremental model 6 big bang model. Traditionally the systems development life cycle consisted of five stages. It is important to note that maintaining strong communication with end user clients is crucial throughout the entire process.
Although there are numerous versions and interpretations of the system development life cycle below are five of the most commonly agreed upon phases and their characteristics. Software development life cycle process. If you want to come up with satisfactory results it is essential to follow all these different stages of the software development life cycle. In this first phase problems are identified and a plan is created.
That has now increased to seven phases. Similar to a project life cycle plc the sdlc uses a systems approach to describe a process. 5 phases of the system development life cycle. Sdlc phases 1 requirement gathering and analysis 2 design 3 implementation or coding 4 testing 5 deployment 6 maintenance.
The software development life cycle sdlc is a process used for structuring the development of any software system from initiation through to implementation. Increasing the number of steps helped systems analysts to define clearer actions to achieve specific goals. Software life cycle models describe phases of the software cycle and the order in which those phases are executed. The software life cycle falls into 6 levels starting from requirements gathering and ending in the maintenance phase.
Systems development life cycle sdlc is used during the development of an it project it describes the different stages involved in the project from the drawing board through the completion of the project.
