Information Decision-Making Support on Elimination of the Defects Detected at Exploitation of Data Processing Systems

We consider a formalized decision support procedure for eliminating defects found during the operation of data processing systems. The procedure is based on a system combination of the models "Defect Profile" and "Interval Probability Estimation Based on Sample Data" by "Boston Consulting Group — BCG".
The concept of "Defect Profile" is introduced into consideration. The purpose of building a defect profile is to develop 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 a certain target user group and the degree of knowledge of the defects.
An approach to constructing a defect profile using actual data with a limited number of observations is described. The approach features the interval estimation of the probabilities of states corresponding to different layers of the profile.
A method is proposed for adapting the approach described in the marketing literature to providing information support for decision-making on investing funds into the activities of the organization's units under uncertainty of the external and internal environment — the Boston Consulting Group (BCG) approach — to the problems of information support for decision-making on defects elimination in Data Processing Systems (DPS).
The use of the proposed approach creates an informational basis for the targeted allocation of limited resources for defects elimination, taking into account their impact on the users' assessment of quality of DPS. An example of the use of the proposed approach based on the results of trial operation of the DIRECTUM electronic document management system is given.
