The analysis of existing methods of determining the expert competence coefficient is carried out. Based on the results of the analysis, it is suggested that experts’ evaluation is made on the basis of objective characteristics and also it is suggested to make a group decision with a margin according to the Harrington desirability function. Approaches are proposed for the components of the expert's competence coefficient that allow taking into account the objective characteristics of each expert – period of familiarity with the problem, the academic degree and position, as well as the number of publications, reports, etc. on the problem. Thus, we get the value of the expert's competence coefficient taking into account his objective characteristics, which will significantly reduce the subjectivity of the experts' evaluation and improve the quality of the expert committee. The proposed group decision made by an expert committee (regarding a problem considered based on the ratio of difference between the sum of competence coefficients of supporter experts and that of dissident experts to the sum of competence coefficients of the experts with a margin according to the Harrington desirability function, which shall be more than 0.8) will allow taking into account the constructive opinions of the dissident experts. This group decision and determination of the expert’s competence coefficient taking into account the objective characteristics of each expert will reduce the influence of human factor, thus ensures more optimal composing of programs for development testing of rocketry items. An example of practical application in comprehensive development testing program (CDTP) of items of the rocket space complex of a proposed group decision made by an expert committee will allow taking into account the constructive opinions of the dissident experts to introduce subclasses in status of qualifications, which take into account the logic of development test the component parts, that contributes to the optimization of CDTP.
