Robert Campbell performs a valuable service to the HCI community in pointing out the several different uses of "scenarios". While the diversity certainly exists, we believe he has mis-ananlyzed it and missed an important commonality. Although he begins his summary by claiming that "scenario" has four major meanings, the examples in his article in fact demonstrate a number of different purposes and applications of scenarios-- which is surely not something to complain about -- drawn from sources which exhibit a significant commonality of meaning.
