Every organisation has some version of the same challenge:
What counts as an "active customer"?
Does revenue get measured net or gross?
Does a "sale" include returns?
The answer exists somewhere: in a finance director's head, in an outdated document, or as a DAX measure in a Power BI model that only one person knows how to maintain. A new analyst joins the team, asks the question, and gets a different answer depending on who they ask.
