Software development is the process programmers use to build computer programs. The process, also known as the Software Development Life Cycle (SDLC), includes several phases that provide a method for building products that meet technical specifications and user requirements. The SDLC provides an international standard that software companies can use to build and improve their computer programs. It offers a defined structure for development teams to follow in the design, creation and maintenance of high-quality software. The aim of the IT software development process is to build effective products within a defined budget and timeline.
