Analysis and implementation phases in the two-segmental model of information systems lifecycle

Analysis and implementation phases in the lifecycle of ERP software packages involve many resources and are most relevant to the buyers of such software. Therefore, it is important for them to understand the objectives of those phases and activities involved with them. The two-segmental model proposed by the authors is aimed at better representation of the life cycle of information systems. This article aims to demonstrate that the actual course of the two phases is better mapped in the proposed model. The classical waterfall model of the life cycle of information systems was used as a reference point for the investigation.
