In different ways and degrees, companies and organizations of today embrace the promises of productivity, knowledge development, and interorganizational connectivity that contemporary information technology (IT) offers. Whether the motives are internal needs or external demands, the goal is increased effi ciency or effectiveness, and whether the argumentation emphasizes added capability or decreased costs, companies have made IT an integral part of today’s business world. This may be manifested in the form of enterprise resource planning (ERP) systems from SAP, knowledge management systems (KMS) from IBM, offi ce packages from Microsoft, or network solutions from Cisco, but organizations likewise face a challenging integration of IT with their established business. By now, many organizations have already passed several cycles of IT implementation, and their current challenges are thus often a matter of migration rather than clean-slate implementations.
