There are no certain rules when it comes to marketing organization structure. Choosing the best CMO org chart for your marketing organization is highly dependent on a variety of factors. To begin, consider the size of the company and the number of employees. If your marketing department consists of only six people, they are most likely wearing multiple hats and reporting to a single manager, so it isn't that complicated. On the other hand, Enterprise organizations may have dozens of people under the marketing umbrella, necessitating a more detailed cmo org chart.
