I work in a research institute where we have operation groups called in many different names such as Office, Branch Office, Group, Unit, Center, Division, Department, Project Team, Section, etc.
I'm now drafting a kind of questionnaire asking everyone in the organization to answer it, and one of the entry items included in it is "Your xxxxxx: ___________."
In the blank, I would like the answers to write the name of the group they belong to, and what I'm looking for is a word or phrase that could best fit in the "xxxxxx" part. Is there any such one word or phrase? One of my colleagues has suggested "Affiliation." Do you agree?
