WHO?
Definition
The word who is a pronoun. When used as a question, it asks for identification regarding individuals or groups. Who is it? is asking about recognition – identify the person or group on the basis of a name, a role, a status, etc. Who are you? asks an individual or group to locate themselves within a particular context, be it place, relationship, or purpose. The person asking usually gives clues about the extent of details being sought. Hence, the parameter who runs from identity to identify.
Purpose
The intention of this question? Is the person or group known to anyone here? Is the person or group qualified or disqualified, eligible or ineligible for some consideration based on identification? Is there more information pertinent to the person’s or group’s identify or status that needs to be verified or processed? When asking such questions, seek the minimum of information necessary. Respect privacy and confidentiality.
Explication
In addition to a name, a person or group likely has some or all of (a) an address; (b) a phone number; (c) a fax number; (e) an e-mail address; (f) a personal or professional web site; (g) a job; (h) a family (spouse, children, parents, other relatives); (i) friends; (j) awards; (k) publications; (l) achievements; (m) failures; (n) a reputation; etc. Some, or all, or none of these might be relevant to a particular enquiry. The aim, presumably, is to keep posing the questions until either the identification, or the specific attributes are revealed, or no further information is shared.
Implication
In situations of either change or continuity, a major question that needs to be raised is "Who are the winners and the losers?" This is one entry point into the concept that is an important aspect of any of the identities and particulars of the people effected. The rationale for this question is "the need to know" so as to assess impacts and arrange for amelioration. Information is power because it provides leverage. Don’t exploit!
