For the acceptance of IT, whether active or passive, the central role of trust and confidence in the IT systems’ context has to be emphasized. The “Case-based Evidence” estimation is based on drawing conclusions from isomorphic “analogy sources” – the “evidences” – to the given case. By a series of expert interviews, the synoptic conclusions – having been made – are evaluated. Some recent example projects show the successful application of the method of “Case-based Evidences” as a Middle Range Theory.
