Based on comprehensive literature evaluations, Philipp H. Grimm provides a definitional derivation of "influence" and systematizes the existing findings regarding the influence of the marketing department. Utilizing economic and behavioral science theories, he presents a theoretical-conceptual framework. To validate the research model, Philipp H. Grimm conducts a written survey and demonstrates that the influence of the marketing department remains substantial. Through causal analysis, the author examines how the influence of the marketing department affects corporate performance and which marketing organizational constructs determine this influence.
