System development ‘life cycle’ has eight phases followed one after the other: investigation, analysis, design, programming, testing, implementation, operation, and maintenance. In the first stage the system development professionals are those who perform feasibility analysis in which they decide whether to leave or modify existing program or develop a new one.

Testing intends to check if the computer codes function properly and to find any errors in them. Implementation is the phase in which an old system is replaces with the new one; it has three main versions where in direct (and risky one) the old system is cut of and the new launched, in pilot the new system begins to work in a certain area first, and in phased two systems are combined gradually launching new components.
