In methods or processes with respect to hearing device adjustments, the workflow of an adjusting operation i.e. sequence of adjusting steps, the adjusting steps themselves and the timing of performing these steps, are not stored. A particular adjusting or fitting operation of a hearing device is performed independent of previous adjustments or fittings of the hearing device. Thereby, most generically, the expertise from previous adjustments is lost after the adjustment is performed, particularly if subsequent adjustments are performed by different individuals, i.e. experts, at different locations. Although, adjustments and fittings of a hearing device are often associated with fitting mechanical characteristics of the respective hearing devices e.g. shape of the shell, surface characteristics of the shell etc., they may also concern adjusting signal-processing of the respective hearing device.
