Evaluating Success in Post-Merger IS Integration: A Case Study

Despite the importance of post-merger IS integration to the success of the whole merger, post-merger IS integration literature remains scarce. This paper attempts to synthesise the often implicit or vague definitions of post-merger IS integration success with those provided in the vast body of literature on IS evaluation. As a result, four categories of success issues for post-merger IS integration are proposed: User satisfaction with the integrated software’s system and information quality as well as its use; Efficient and effective IS integration management; Efficient IS staff integration; and IS ability to support the underlying motives of the merger.
