What is SDLC? Ist it Systems Development Life Cycle or Software Development Life Cycle?

SDLC: Software Development Life Cycle

System Development Life Cycle

Speaking from formal software engineering point-of-view, SDLC stands for "Software Development Life Cycle". Which is a process that begins from understanding the system-as-is (i.e. business process(es) and/or features of current software in-service"  and then, gathering the customers' requirements/needs that to be handled in the system-to-be (i.e. final software system to be deployed). Then, it is followed by a set of pure technical stages of: software architecture, software design, software implementation, software testing, software maintenance.

In my point-of-view, since we are living in a rapidly-changing world ! SDLC would not anymore strictly governed by thoughts of field experts or academician. It is only the business which will steer SDLC to customize its processes/stages in order to fulfill the business philosophy and needs of the enterprise. This would be true in both: outsourcing or in-house development software solutions.

SDLC is software development life cycle starting from activities requirements,analysis,design,code/implementation then test and maintenance.

The most important thing when we apply SDLC that we have to be aware that the new functional and non functional requirements are properly integrated with the existing process.

SDLC: System Development Life Cycle 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 system life cycle is a term used to describe the stages in an IT project. It is the process by which an existing system is replaced with another. The systems development life cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project, from an initial feasibility study through maintenance of the completed application.The systems development life cycle (SDLC) is a theoretical model that is used in project management to describe each of the stages that are involved within an information system development project, from the initial feasibility study through to the maintenance of the completed application.There are four Quadrants :

Quadrant1: Determine objectives, alternatives, and constraints.

SDLC Stands for System Development Life Cycle , and it is the way that lead to facilitate the development of new system , This stage of Software and system Development  is the initial stage  of developing new system , This stage usually done by  the specialized system analyst who will investigate the work fall scenario from the  key  users , or System Administrators , etc .. who will use the system  , the system analyst will draw the model life cycle to express the stages and process of the suggested system to be done .

By definition the SDLC stands for Systems Development Life Cycle.

But, in essence, the process that governs the flow of business and client problems from their initial stages down into a full-fledged solution in any computerized means; can be used as definition for Software Development Life cycle as well.

It is both System Development Life Cycle and Software Development Life Cycle.
