Hold monthly or quarterly conference calls or in-person meetings with all of your agency partners. Use this opportunity to discuss the overall direction and specific upcoming campaigns. This will help create a cohesive marketing plan of attack and a well-coordinated end product. Often, although they are initially averse to the concept, many agencies walk away with the understanding that working together on specific initiatives enhances and increases the effectiveness of the overall campaign and better satisfies the client in the end.

After you get these things under control you have the challenge of making sure that your agencies don’t engage in turf wars. By connecting everyone, you help define each of their sandboxes.
