Systems development life cycle

This circular arrows diagram sample shows the systems development life cycle (SDLC) stages.
"The systems development life cycle (SDLC), also referred to as the application development life-cycle, is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system. The systems development life-cycle concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both."

The arrow circle diagram example "Systems development life cycle" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Circular Arrows Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park.

This IDEF0 diagram sample was created on the base of the figure from the website of the Engineering Laboratory of the National Institute of Standards and Technology (NIST). [mel.nist.gov/ msidlibrary/ doc/ kc_ morris/ gsa-final_ files/ image002.gif]
