Software development life cycle sdlc is a process used by the software industry to design, develop and test high quality softwares. Further information about safety and security extensions developed for this. Process life cycle an overview sciencedirect topics. A process for the management of risk in the life cycle is defined. It then creates the software through the stages of analysis, planning, design. In practice, processes occur whenever they are needed within any stage. The goal of process analysis is to detect implicit knowledge that exists in the. In systems engineering, information systems and software engineering, the systems development life cycle sdlc, also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. It is also relevant to software engineering process group sepg members who want. The sdlc aims to produce a highquality software that meets or exceeds customer expectations, reaches completion within times and cost estimates. The base document isoiec 12207, establishes a common framework for software life cycle processes, with welldefined terminology, that can be referenced by the software industry.

It contains processes, activities, and tasks that are to be applied during the acquisition of a software product or service and during the supply, development, operation, maintenance and disposal of software products. It uses unit design and unit implementation information, in addition to unit. Heres a common definition of the software development life cycle. The data life cycle is the sequence of stages that a particular unit of data goes through from its initial generation or capture to its eventual archival andor deletion at the end of its useful life. Sdlc is the acronym of software development life cycle. Sdlc provides a wellstructured flow of phases that help an organization to quickly produce highquality software which is welltested and ready for production use. Thus this standard provides industry a basis for software practices that would be usable for both national and international business. This begins to explain the nature of the sdlc as a planning mechanism.
