Expert surveys – use the experience and knowledge of experts
Expert surveys are a suitable measure to generate short-term knowledge about certain topics or current developments and forecasts. Experts are people who, due to their training, experience or knowledge, are able to make such statements.
When evaluating expert interviews, care must be taken to ensure that expert reports are not free from subjective evaluations, wishes or goals (see Kahnemann, Daniel / 2011: Die Intuition vonexperts, p. 289 ff). Expert surveys are therefore ideally combined with other procedures and methods, e.g. desk research or forecasting procedures, and thus additionally secured.
A more structured and systematized survey technique is the so-called Delphi method , in which a group of experts deals with different aspects of a forecasting problem under guidance in several rounds.
