  • Systems Development Life Cycle (SDLC), or Software Development
    Life Cycle, in systems engineering and software
    engineering refers to the process of creating or altering systems, and the
    models and methodologies that people use to develop these
    systems. The concept generally refers to computer or information systems.

  • In project
    management a project has both a life cycle and a "systems development life cycle,"
    during which a number of typical activities occur. The project life cycle (PLC)
    encompasses all the activities of the project, while the systems development life cycle
    focuses on realizing the product requirements.

  • • Systems Development Life Cycle (SDLC) is any logical process used by a systems analyst to
      develop an information system, including requirements,
      validation, training, and user ownership. An SDLC should result in
      a high quality system that meets or exceeds customer expectations, reaches
      completion within time and cost estimates, works effectively and efficiently in
      the current and planned Information Technology infrastructure, and is
      inexpensive to maintain and cost-effective to enhance.^[
    • Systems Development Life Cycle (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 are several Systems Development Life Cycle Models in existence. The
      oldest model, that was originally regarded as "the Systems Development Life
      Cycle" is the waterfall
      model: a sequence of stages in which the output of each stage becomes the
      input for the next. These stages generally follow the same basic steps but many
      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 Systems
      Development Life Cycle model, but the steps can be characterized and divided in
      several steps
