Maybe create a slack channel (or some other listing on one of the shared platforms) to announce when a new contact has been created in Salesforce. It may be useful to know and keep a record of when new individuals are interacting with us and from what accounts.
Also, a 360 course or confluence page on how to create a new contact would be good for new associates to learn and have a guide on how to make new ones, since it's a pretty important thing to do and having to tag or ask someone who knows how if you're uncertain can really slow down processing a request.
