Ask a company's AI assistant for last month's revenue, and it first has to decide what the word means. Does it include sales tax and delivery charges? Are returned orders taken off? The data does not answer these questions. Even a small online shop has four different revenue figures in four of its systems.
So the sales director gets one answer, the finance director's monthly report shows another, and the person who knows the real number decides the tool is wrong. After two or three of those moments, they go back to the spreadsheet.
The AI did not create the disagreement. Each department always had its own version of revenue, kept in its own spreadsheet, where nobody compared them. An assistant that answers everyone from the same data puts those versions side by side.
The fix is about thirty years old: write down once what each disputed word means, and make every tool use that definition. AI can now draft the definitions from existing reports, so the real work is the meeting where people agree.
For example, a finance director could list the five numbers that cause the most arguments, such as revenue, gross margin and on-time delivery, and name one owner for each. The agreed definitions go into the instructions that the assistant reads. Then someone asks the assistant each question and compares its answers with last month's board report. A week of short meetings buys a tool that people believe.
