Why Your Month-End Margin Moves When Nobody Changed the Query

Finance closes on calendar boundaries while operations ships on rolling cycles—your margin numerator and denominator rarely honor the same calendar quietly.

Start by printing the grain statement for every metric on the executive deck: what row counts as a sale, when recognition happens, and which filters travel between worksheets. If three departments answer differently, fix language before touching SQL.

Next, snapshot dimensional bridges weekly—not only at quarter close. Late adjustments love hiding inside innocent-looking joins refreshed overnight.

Finally, pair analysts with a counterpart from finance fifteen minutes before decks finalize. It feels ceremonial until it catches the drift we dissect in KPI Architecture Workshop.
