Problem:

Product Owners (nondesigners) will often times share early work in progress without the designer knowing. This ends up being a headache of dev comments (30+) pinging with comments that designs are not complete or components are not built correctly.

Solution:

Designer who is the owner of the file can assign specific users/staff so they get all push notifications/emails 

Reason:

To help each team member own accountability for the consequences of their action. If a product owner wants to share an incomplete file to 100+ people in the organization without communicating the designer. Let’s ensure the push notifications/emails get sent to the product owner that initially share a file too early to help respond to each comment.
