Management of innovations

The developers and technologists of information systems design and explore decision support systems over 35 years. They emerged at the beginning of the distributed computer processing, but their history is not so straightforward and linear. That is why it is necessary a short retrospection and analysis of their development to be made, before exploring the contemporary systems of such type. Before 1965 it was too expensive to design a broad range information systems based on high class computers and that is why, the big companies have accepted more practical and effective (from cost point of view) approach to develop Management Information Systems (MIS). These systems centered on supporting managers by structured, periodical reports, gathering information mostly from accounting and transactional systems
