The most appropriate report format for sending an informational update to your supervisor on a consulting project would typically be e-mail or memo format.
Why are these formats better
E-mail or memo formats are concise, direct, and suitable for quick communication of project updates.
E-mails or memos allow for a clear presentation of key information, making it easy for your supervisor to quickly understand the status of the project.
They are commonly used in professional settings for brief updates, status reports, or general communication.
