Abstract
Mergers & acquisitions feature prominently in today’s business world. At the same time, numerous failed transactions exemplify that the integration of enterprise resources requires special management attention. As corporate value chains become ever more permeated with information technology, integration in mergers & acquisitions increasingly turns into an issue of combining firms’ IT-resources.
In face-to-face interviews with IT-managers, detailed insights into the integration of data centers, application suites and IT-organizations were gained for 20 horizontal, synergy-oriented mergers & acquisitions. A contingency model is used to analyze different integration practices for their situational drivers and success impact. The results offer support for business and IT-management in successfully integrating IT-resources in mergers & acquisitions.
