Business Modeling in the Process of Information Systems Development

The paper aims at presenting the role and importance of business modeling in the software generation process. The business model is the simplified description of the organisation that allows designing the optimal information system (iS) satisfying the needs of the user and allowing achievement of the company goals. Both generation and integration of information systems are dependent on the business modeling quality. The Enterprise Architect tool and the object approach were used for drafting the description of phenomena and processes taking place within the organisation. This allowed presenting the organisation in two perspectives: external and internal. Understanding the perspective that was considered in designing the given model is an important factor influencing appropriate interpretation of the model and its correct use in the information system development process.
