Systems Development Life Cycle has historically been a very useful tool in the development of software and operating systems in Computer Information Technology. Through the Systems Development Life Cycle there are at least five distinct phases that are delineated and performed within a linear patter. Meaning, that each step must be complete or at least very close in order for the next set of experts to begin the next phase of work on a project. It has been historically thought that each stage's crucial addition to the whole project is a building block necessary for the next phase of project development, therefore circular or spiral models, where all or some phases occur simultaneously was thought difficult to impossible for application within the information technology application.
