Synthesis of the Life Cycle Stages of Information Systems Development

The problem of agreeing points of view on the target system being developed, often inseparable from the problem of mutual stakeholders understanding in the process of information systems development, as a special case of complex technical systems, is one of the most fundamental today. The paper considers the solution of this problem and suggests a methodology for the synthesis of the stages of the information systems development life cycle. This methodology assumes two models: a model for creating knowledge (concepts), and a model for reconciling knowledge. In the paper the main aspects of these models and the process of their use are considered. The ideas proposed in the work are aimed at formalizing the process of information systems development and removing the empirical component that currently present in the information systems design.
