EFFICIENCY AND EFFECTIVENESS OF USE OF INFORMATION SYSTEMS

Abstract

The use of information systems in business implies  on the one hand that IT-systems are constantly  adapting  to the requirements of the company as business processes are changing  all  the  time.  On  the  other  hand  business  processes  should  be  aligned  with  technical capacities of IT-systems as they develop very quickly. This approach is called Business-IT Alignment in IT management. Unfortunately the  reality is there are  significant gaps and weaknesses in the management and use of information systems. This leads to the decrease of efficiency and  effectiveness of the  business processes support. Reverse Business Engineering or to be more exact  regular diagnostics used  in the  IT area  can help  to fill in the gap between business and IT by tracking transaction data, logfiles,  and user behavior. This approach requires a comprehensive analysis  of information systems  to determine system modification, unused capacities, business process deviations, etc. So, fixing weaknesses that were  found in this way in information systems  and  business processes improves dynamic business strategy support and increases competitiveness.
