Final answer:
Brandon's use of a newsletter as the sole communication tool may result in Undercommunication (option E) according to Kotter's principles, which suggest utilizing multiple channels to ensure effective organizational change.
Step-by-step explanation:
If Brandon uses a newsletter as his organization’s only communication tool, according to Kotter, this communication channel may result in Undercommunication. Kotter's principle emphasizes the importance of using every vehicle possible to constantly communicate the new vision and strategies and the need for a change. He suggests that transformation is impossible unless hundreds or thousands of people are willing to help, often to the point of making short-term sacrifices. Relying solely on a newsletter could fail to create a sense of urgency or fail to gather sufficient support.
Newsletters might not reach all employees frequently or compellingly enough to effect significant change. In contrast, Kotter advocates for utilizing multiple channels of communication that can include face-to-face meetings, emails, and multiple other platforms to ensure the message reaches everyone in the organization. The problem with using only a newsletter is that it might not be enough to convey the urgency or importance of the vision, leading to the possibility that the needed change will not be effectively communicated across the entire organization.
