    This work aims to develop a methodology for determining the qualitative composition of an expert group and the weighting factor regarding the importance of expert’s judgments for the purpose of participating in decision-making. It is based on the expert’s overall work experience, experience in solving tasks, level of education and scientifi c record, interest in solving the particular task, current position and awareness of how to solve the task. This study also considered the relevance of the expert’s knowledge and the overall self-evaluation concerning their total competence in solving the task. For the purpose of validating the methodology, 96 potential experts (physicians, biomedical engineers, radiological assistants, medical physicists, etc.) from 72 health facilities in the Czech Republic were interviewed through a web-based questionnaire. The calculation model that was selected was able to eliminate errors in estimating the proportionality of extreme values and reduces the impact of uncertainty in the experts’ overall self-evaluations concerning their total competence. A statistically signifi cant correlation was found between the complex weighting factor and the following characteristics: the expert’s experience in dealing with similar tasks (r = 0.512, p < 0.001), the expert’s theoretical background (awareness) and the relevance of the expert’s knowledge (r = 0.440, p < 0.001), the expert’s current position (r = 0.319, p = 0.002) and the level of his or her education and scientifi c record (r = 0.280, p = 0.007). The developed methodology may be especially useful in scientifi c and technological forecasting, medical and managerial decisionmaking, quality assessment and operational research.
