There´s one way to improve significantly communication on his team. Julio H. Pimienta Prieto is a Cuban educator and he suggests different schemas to organize information, this can help a manager organize and delegate responsabilities.
A box schema can help organize and delegate activities withouth overwhelming a marketing director. The manager could draw many boxes in a whiteboard and all of this boxes would be connected one with another narrowing down until there is one on the top. He could write every activity for every department assigning their specific tasks, so this way the marketing director wouldn´t be so stressed for having many things to do.
