The importance of effective sales and marketing working relationships is well known and this article examines the effectiveness of various coordination mechanisms used to improve this cross-functional relationship. Six coordination mechanisms are measured to identify their effect on sales and marketing conflict and collaboration, which in turn influence business performance. The results reveal that not all coordination mechanisms are equally effective. Structuring sales and marketing as a single unit and creating crossfunctional project teams improve the interface, as do providing opportunities for job rotation and establishing cross-functional meetings. However, employing crossfunctional training and co-locating sales and marketing do not influence this working relationship. Finally, reducing conflict and increasing collaboration between sales and marketing is shown to independently, and positively, influence business performance.
