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." [Systems development life-cycle. Wikipedia]
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 arrow loop cycle diagram sample was created on the base of the figure illustrating the webpage "Exploratory Advanced Research Program Hand-Off Workshops" from the US Department of Transportation - Federal Highway Administration (FHWA) website. "The FHWA’s research and technology innovation life cycle illustrates that research and technology development are not insular activities, but integrated processes that together constitute a system.
Following general workshop discussion, a number of common issues emerged among the groups. These centered around the research life cycle, communicating the value of exploratory advanced research, and continued project funding. It was felt that there is a general need to better describe the research and deployment cycle specific to highway transportation and possibly to highway research fields, such as materials or system planning. Research life cycle diagrams show a very linear, chronological process but it is not necessarily that way in reality." [fhwa.dot.gov/ advancedresearch/ pubs/ 11034/ ]
