Marketing organizational design changes can have professional and personal implications for internal audiences and often fail when communications are deficient or absent. While certain information must be kept confidential, it’s important for CMOs to collaborate with communications leaders and share as much information as possible. By leveraging their expertise, CMOs can effectively plan both internal and external communications. Driving understanding and adoption of organizational changes requires effective communication throughout the process. A communication plan is critical for ensuring a clear and consistent approach to disseminate essential information to all audiences affected by the change.
