  • A requirements analysis - analyzes the information needs of the end users
  • The architectural design - creates a blueprint for the design with the necessary specifications for the hardware, software, people and data resources
  • Coding and debugging - creates and programs the final system
  • System testing - evaluates the system's actual functionality in relation to expected or intended functionality.

(3) Acronym for software development life cycle (SDLC) and also synonymous with software process as well as software engineering, it is a structured methodology used in the development of software products and packages.
