According to the media, information system projects seem to fail very often. Via these failures, the enterprises and organisations are losing a lot of money, resources and customers. Sometimes organisations seemed to lose something more valuable than money: the self-assurance. An organisation without selfassurance will postpone all development efforts and it will start them too late and probably without highlevel targets. Unsuccessful projects aggravate organisations’ competitiveness and therefore the successful of IT projects is an economic issue.
