The heterogeneity of the social structure of modern society changes the image of a "working man." Well-established images prevailing in the XX century (an economic man, a functional man, a psychological man) are replaced by a new image--"a self-organizing man." This construct describes a "smart" class. According to Y.V. Gromyko (2013), this group includes people of different professions: engineers, designers, economists, humanitarians, educators, teachers, scientists, and investors who are able to manage the development of new technologies. The idea of this "smart" class is determined by its ability to self-organization, self-control, conscious and meaningful self-regulation, self-management and self-development. Creating a psychological system of professional dedication and verifying the individual viability of the system have a theoretical and practical importance for determining the development direction of modern professional work in the context of relations "man-man." In this study, to evaluate dedication "Utrecht scale of dedication to work" was used, to evaluate engagement--Questionnaire Q12 Gallup Organisation. This research defines and describes the model of psychological system of personal professional dedication at the component level. Connections between system components of professional dedication are empirically identified and made explicit: professional demand and professional identity as the resulting figures of professional dedication, motivation, self-regulation and involvement. An important result of this study is conceptual completeness and reliability of the model of psychological system of professional dedication. The article can be used for designing strategies of individual professional development, depending on motivation, level of self-control, involvement and focus on professional demand and professional identity. Model of psychological system of professional dedication will allow working out organizational conditions for dedication development in professional activities as an additional motivation for a successful professional career.
