Information Support for the Management of the Efficiency of Enterprise Information Service Systems

We are considering a formal procedure to support the management of the efficiency of enterprise information service systems in a part of defects repair found at the stage of operation of such systems. The basis of the procedure is the system combination of some models and approaches. The term of "Defect Profile" is considered. The purpose of building a defect profile is development of a systematic basis for decision making in the allocation of resources for finding and eliminating defects, taking into account their importance from the point of view of various user groups and the degree of defects knowledge. An approach to constructing a defect profile from actual data with a limited number of observations is described. A method based on the BCG-approach has been proposed for adapting to eliminating defects. This approach is described in the marketing literature. It is used for making decisions on investing funds into the activities of an organization's units in the face of external and internal environment uncertainties. The use of the proposed approach creates an informational basis for the targeted distribution of limited resources to eliminate defects, taking into account their influence on the users' assessment of information systems quality.
