Direct answer
A reporting workflow identifies the source of each input, its owner, the transformation and the person who reviews the output.
Trace the source of each value
Capture where information came from, its date and any assumptions. Data without context is hard to compare and harder to maintain.
Design an output for a decision
Separate measures, explanatory notes and uncertainties. A reader should be able to tell what is measured and what is an editorial interpretation.
Document changes
If a method or input changes, note the version and affected pages. The demo template includes dates and structured sources so buyers can build a stronger record.
