The Systems Cycle

The SYSTEMS LIFE CYCLE is a term used to describe the stages in an IT project. These are:

	Definition of the problem
	Feasibility Study
	Investigation and Analysis
	Design
	Development (programming)
	Testing
	Implementation
	Evaluation
	Maintenance

Notice that the term 'life cycle' is used. This is because the process never really ends. Systems are created, they become mature, they grow old and are replaced by new ones. It is a cycle.
