The prospects of the business organisation reliance on information system supported by the information and telecommunication technology is shown. It analyzes the frequency of information system failures and the costs that arise.

It is also shown that the failure of information systems for business organisations is a major threat because of their frequent occurrence and because of significant financial losses it causes. In conclusion, the hypothesis is discussed and some directions for further research on the dependability of the information system supported by information and telecommunication technologies is presented. The aim of the paper is to show the importance of information system dependability to the scientific and professional community and thereby to promote research and professional work in this field.
