RT Journal Article SR Electronic T1 Integrated Marketing Communications (IMC): Why Does It Fail? JF Journal of Advertising Research JO J Advert Res FD WARC SP 132 OP 145 DO 10.2501/JAR-55-2-132-145 VO 55 IS 2 A1 Mart Ots A1 Gergely Nyilasy YR 2015 UL http://www.journalofadvertisingresearch.com/content/55/2/132.abstract AB Integrated marketing communications (IMC) is accepted widely as a multi-stakeholder strategic business process for brand communications. Yet, much less is known about the failures of its practical implementation. The current research provides a novel explanation for such failures. A two-year ethnographic study was conducted with a large Swedish retailer and its IMC partners. The objectives were to reveal potentially divergent managerial mental models and to understand the consequences of such divergence on IMC implementation. The authors' findings uncovered four basic mental models, which, in turn, revealed four aspects of IMC implementation dysfunction: miscommunication, compartmentalization, loss of trust, and decontextualization.
