Field parameters when teams disagree on the same chart

Field parameters shine when two departments want the same chart skeleton but different measures. The failure mode is letting every measure into the dropdown. We start with a curated list tied to documented decisions, then add a "request a metric" link that routes to a short form instead of expanding the dropdown blindly.

We also coach analysts to name measures for spoken language. Long internal names look fine in the field list but sound awkward on a call. A simple rename pass before publishing reduces confusion more than any tooltip polish.

Finally, we snapshot the parameter definition in Git-like change logs. When someone asks why a metric disappeared, the log answers faster than digging through version history alone.
