IT Productivity

Despite high initial investments, many IT projects do not achieve the expected economic success. The question was recently brought up again in the literature: to what extent investments in IT lead to an increase in general productivity both at the national level and company level. Carr even postulated a commoditization of IT in his polarizing article, "IT Doesn't Matter".

Hence this research focus looks mainly at economic and technological questions regarding productivity measurement and economic viability of IT system solutions. The main idea is to examine the measurement of success from investments in IT such as shop systems, ERP modules and CRM or distribution systems. We develop new approaches which allow for the quantification of the success of such projects.

This area of research is inter-disciplinary and integrated to the fields of business modeling, data mining, web services, and data protection. This results in research methods from web use analysis, databases, classical hypothesis testing methods, as well as questionnaires and experiments. Thus methods like E-metrics are developed which quantify the success of more recent internet based business models ("Web Controlling"). Such operating figures are based on comprehensive of users and user behavior, product and turnover data as well as external data. The detailed analysis of personal data potentially brings conflicts regarding data protection regulation. Therefore the evaluation of the efficiency of new data protection technologies plays an important role. Thus a cost-benefit analysis also needs to be considered in the context of a new and current legal regulation.

To assess the efficiency of IT process integration, the theory on transaction cost may be applied. With methodological approaches from information economics, instruments have been developed in order to repair weak spots in the transaction process.
