The purpose of this study is to create a model of a relationship in which the dependent variable is the result of a project and the independent variables are the characteristics of human resources. We attempted a comparative evaluation of discriminant analyses with a statistical model and a machine learning model using assessments of the results of projects and team characteristics derived from questionnaire survey data. The results of the evaluation demonstrate that the machine learning model shows a higher discrimination rate within the range of the data used in the analysis, but it became clear that the discrimination rate worsens in comparison with the statistical model when extrapolated.
