Problems of computational resources demand growth
Often IT-department is perceived as a wasteful department though in practice just this department provides basis for effective work of present day organization. The problem is that commonly only expenditures for IT-infrastructure are taken into account and its services cannot be counted. This fact disturbs not only IT-department for which it is difficult to prove new expenses for development and maintenance of systems but also users for which it is difficult to receive service of required quality in time. Moreover this approach results in inefficient usage of available resources.
