Existing theory suggests that to successfully integrate information systems post-acquisition, an acquiring company must leverage two capabilities; diagnosis and integration execution. This paper seeks to understand how an inexperienced acquirer can develop these capabilities in anticipation of an acquisition. It uses a case study to understand the learning processes a novice acquirer engages in as they develop them. It finds the novice acquirer, applies trial and error, experimental, and vicarious learning processes, while actively avoiding improvisational learning. The results of the study contribute to the existing acquisition IS integration literature by specifically addressing the limited understanding of how novice acquirers can learn the required IS integration capabilities.
