Basically, the Digital Team will make a change and approve content without informing the content submitter when the change is viewed as minor. Often, these are changes involving grammar, punctuation, spelling, or conformity with university style (see the University Style Guide). There are simply too many content submissions to send emails about each minor change.
The Digital Team will notify the content author/approver of a change made before publishing when the change is significant or when the change is something likely to come up again in future submissions by that author/approver. Often, a member of the Digital Team will contact the unit author/approver to help with fixing the submission.
Basically, the Digital Team will decline content when it needs significant work that would be most beneficial for the author/approver to do in order to improve future submissions. The unit author/approver is always informed of the reason by email or phone. Often, a member of the Digital Team will work with the unit author/approver to improve the content.
