Alerts to staff for office document changes

Hi all,

Am hoping you will be able to offer a solution for me. Currently my office “guide” - think policies, processes, procedures etc are in a word doc. which is edited as require by management.

In an ideal world, when this document is updated it would alert my (specified) team as to the Document and the update made. We are currently using Sharepoint and it seems I can create an alert for myself however am seeking a mass group alert notification (including the amendment/change)

Any suggestions welcomed!
