Stored in a computer are scores related to answers given by human representatives of organizational units in response to defined questions. For the organizational units, total scores and weighted total scores are calculated. The weighted total scores are calculated by adding up weighted maximum scores assigned to the questions, the weighted maximum scores depending on the respective organizational unit and the respective question. Competence levels of the organizational units are calculated by scaling the total scores of the respective organizational unit to a scale of competence reaching from zero to a maximum competence. The maximum competence corresponds to the weighted total score calculated for the respective organizational unit. The computer generates a graphical representation of the competence levels for multiple organizational units of a particular organization. In one common graph, the competence levels are visualized so that deficiencies of the competence levels from the maximum competence as well as differences between the competence levels of the organizational units are visualized.
