SDLC Methodologies

SDLC Methodologies

A software development process is a structure imposed on the development of a software product. Synonyms include software life cycle and software process. There are several models for such processes, each describing approaches to a variety of tasks or activities that take place during the process.

Systems Development Life Cycle (SDLC) is any logical process used by a systems analyst to develop an information system, including requirements, validation, training, and user ownership. A SDLC should result in a high-quality system that meets or exceeds customer expectations, reaches completion within time and cost estimates, works effectively and efficiently.

Some well-known SDLC models to manage the complexity in traditional systems are waterfall, fountain, spiral, build and fix, rapid prototyping, incremental, synchronize and stabilize.

Methodologies in use over the recent years:

  • Agile methodologies, such as XP and Scrum, focus on light-weight processes which allow for rapid changes along the development cycle
  • Iterative methodologies, such as Rational Unified Process (RUP) and Dynamic Systems Development Method, focus on limited project scopes
  • Sequential or big-design-upfront (BDUF) models, such as Waterfall, focus on complete and correct planning to guide large projects and risks to successful and predictable results
  • RVN consultants are trained well with all traditional and latest SDLC methodologies to meet the clients need on time with quality.
