The improvement of competences in relation to the solution of everyday tasks of production practice is best carried out in the process of training at the workplace due to the combination of acquired theoretical knowledge with practical experience. An urgent task of evaluating the effectiveness of training at the workplace is the diagnosis of the level of preparedness of the personnel of a multimedia company for scientific and technical activities, which can be carried out on the basis of the use of an appropriate information model of personnel development. The purpose of the article was to implement the development of a system model for the formation of professional skills in specialists of multimedia technologies of the polygraphic profile. The article proposes a method of informational support for personnel development through on-the-job training. As a framework that explains the knowledge and skills for the effective implementation of training in the workplace, the current content of competencies is considered. The key areas of personnel qualities related to multimedia technologies are systematized. As part of the conducted research, an information model was created and competence formation was tested within the framework of the relevant modules. The impact of engineering and organizational skills on improving the competencies of multimedia technology specialists is considered. The main components of success in the formation of professional skills of personnel as a result of training at the workplace are considered and analysed. As a result of the work carried out, recommendations were made on the diagnosis of the levels of training of personnel of multimedia and computer companies to improve their own scientific and technical activities, the choice of the content of professional training of specialists in the multimedia profile, the application of a systematic approach to the formation of relevant skills and abilities. A morphological matrix of the formation of technical creativity skills of the personnel of a multimedia company in the process of training at the workplace was created. With the help of Shannon’s information system, a mathematical model of the formation of relevant special modules of competences was obtained. Emphasizing the technical component, the influence of engineering and organizational skills in the process of training at the workplace is considered. The entropy level of the learning system was calculated before and after receiving information. The dependence of entropy on the level of acquired knowledge was analysed. The practical significance of the obtained results lies in the formation of practical recommendations for the management of computer and multimedia companies for the organization of training at the workplace, as a result of which employees receive positive incentives for the development of relevant competencies.
