What are the 5 phases of system development life cycle?
With all the complex processes involved in software development, it’s easy to forget the fundamental process for a successful software development life cycle (SDLC). The SDLC process includes planning, designing, developing, testing and deploying with ongoing maintenance to create and manage applications efficiently.
What are the stages of system life cycle?
systematic process, known as a system life cycle, which consists of six stages: feasibility study, system analysis, system design, programming and testing, installation, and operation and maintenance. The first five stages are system development proper, and the last stage is the long-term exploitation.
What is the difference between system development life cycle and software development life cycle?
The software development life cycle focuses exclusively on software components, such as development planning, technical architecture, software quality testing and the actual deployment of the software. Put simply, the system development life cycle is more holistic and comprehensive.
