Context unlocks meaning

A finance export from coffee distributor InsightCorp landed on your desk. The owner is comparing this year's end-of-quarter promo campaign against last year's, so they need each item's gross revenue before the Q4 discounts were applied.

The export is already attached, but the columns are internal codes. First, ask the assistant for each item's pre-discount gross revenue. Then re-ask with the dictionary below included, and compare the two answers.

Dictionary: rev_q4_adj = gross revenue with end-of-quarter discounts already subtracted (i.e., post-discount); it_nm = item name; unt_sld = units sold; mar_pct_n = net margin % after discounts.

Which best describes how the AI's answer changed once you gave it the dictionary?

Move from raw data to insights you can defend.
