Pg. 1" "We regularly carry out risk analysis as part of a risk management process on which we base corresponding measures including those relating to human trafficking and forced labour. Our present risk analysis is based on geographical origin, the raw materials purchased, the quality of the goods supplied and the nature of the business transaction. AUMA Riester carries out the risk analysis itself."

The company does not specifically reference a questionnaire or a specific risk-analysis tool, but they do refer to the fact that they conduct this risk analysis themselves, which makes me lean toward the "conducting research" answer.

They certainly do have a risk-analysis process in place, but the exact mechanism utilized is unclear.

I think the "on-site audits and written surveys of suppliers" might be considered management tools?
