URS is also an acronymn for User Requirements Specification. It is possible that they are looking for someone who has experience in a formal review process. I would suggest searching on the concept of reviews for this one and see what you get.
So what would one do in a User Requirements Specification Inspection ?
Make sure the Company Logo is correct and they are using the right fonts ?
Usually the term is Requirements Review. The term User Requirements Specification Inspection seems to focus on a physical document, not what the user actually wants. But hey its just nomenclature at the end of the day.
Its not a right or wrong issue. A better term is Requirements review. Requirements exist regardless if they are specified or not. focusing on a document limits the thought process. A URS is merely a collection of such.
My view is there is too much focus on a written document and not enough on what the user wants.
The URL you gave is merely a checklist used during a typical requirements review. It fails to suggest that there may be requirements not documented.
The second example is a better written checklist and does pose what I am suggesting.
