Technological and social changes require the use of innovative solutions in the field of training systems using modern technologies in the area of developing employee competences. An example of such solutions are e-learning platforms such as MOOCs (Massive Open Online Courses), which are becoming more and more popular both among service providers as well as among users. The thematic diversity of training offered on MOOC e-learning platforms allows them to be widely used to develop the competences of employee teams and project teams, while minimizing the costs of acquiring them. The aim of this article is to present, based on case studies, the use of e-learning training on MOOC platforms to develop the competences of employee teams, including project teams. The success of e-learning platforms such as MOOC provided by the CBA or the platform PARP Academy, provided by the Polish Agency for Enterprise Development, which enable the development of employee competences understood as knowledge, skills and attitudes of the employee/personality traits of the employee, in various areas of socio-economic life, indicates the increasing role of this type of tools in the analysed area.
