What type of message is a memo announcing the appointment of a new CEO?

A memo announcing the appointment of a new CEO is categorized as an informative message because its primary purpose is to convey specific information to the intended audience, such as employees, stakeholders, or the public. The memo provides details about the new appointment, including the name of the CEO, their background, and the implications of this leadership change for the organization. This type of communication is straightforward, focusing on delivering important facts without necessarily trying to persuade or direct action from the recipients. Being informative allows the organization to ensure transparency and keep everyone updated about critical changes within the leadership structure.
