Yes. I believe it's Treasury Board policy that all departments should use a limited number of categories. I believe there are five or six categories of requester: business, media, organization, public, and maybe lawyer. The software, the computer programs used by each department, is designed so that the departments are able to add their own categories, and most of them do. For example, all of the departments that I have examined have added a category known as “political party” or “Parliament”, so that they can classify those requests that are coming in.
Other departments have developed other categories for their own internal purposes as well. The one case that I mentioned was the Department of National Defence, which in its system has seventeen different categories for classifying incoming requesters.
