Richard, et al said:
“As regards the Data chart, I agree that Assumptions isn't a good label, and I really like Perspectives. It's more respectful than Assumptions, and it's more self-describing than Data.”
I’m attracted to the Latin derivation: “something given.” If I write a statement on the data chart and there is disagreement about it being a given, then energy is generated that is useful for the group. Lacking consensus, I’ll test the group to see if the statement goes into concerns or gets re-framed as a problem statement. My feeling is that if the chart is labelled otherwise, potentially controversial items can sit on that chart as an “agree to disagree”, unchallenged and unexplored.
Dictionary.com says
Usage note: Data was originally the plural of the Latin noun datum, meaning “something given.” Today, data is used in English both as a plural noun meaning “facts or pieces of information” and as a singular mass noun meaning “information”
