The Lifecycle of Corporate Information Systems

The paper contains analysis of the lifecycle of corporate information systems. Unlike similar works, there is overview from business case to termination of using software product, not limited only by implementation project in the given article. The entire lifecycle is divided into three parts: pre-project, implementation project and post-implementation phases. The most of scientific papers on information systems describe the implementation project, paying less or no attention to pre- and post-projects. It is concluded that the lifecycle of corporate information systems is spiral, but not linear, in addition, the phase of termination is completed only when the implementation of a new and more advanced software product will be done.
