Prompt patterns for turning raw data into readable business reports

Quick answer

Give the model the computed figures, not the raw data; tell it the audience and length; require it to quote only numbers you supplied; and ask for a list of claims to verify. These four constraints remove most invented statistics.

Language models summarise well and calculate badly. The safest pattern is to do the arithmetic in a spreadsheet or statistics package, then ask the model to explain results you have already computed.

Four patterns

  • • Role and audience: "Write for a non-technical operations director, 200 words."
  • • Closed numbers: "Use only the figures in the table below. Do not estimate or round differently."
  • • Structure: "Three headline findings, one risk, one recommended next step."
  • • Self-check: "After the summary, list every number you used and where it appears in the table."

Always verify

The self-check list makes review a two-minute job: compare each listed number with the source table and correct anything that does not match before the report leaves the team.
