The paper examines the authors’ concept of the MOMENTUM Model as a Human Capital development tool. The focus is on the psychological costs of work and on creating a proactive approach towards career development strategy as well as on providing effective operational equipment for human capital development and psychological costs reduction in organisations. The MOMENTUM Model describes four types of experts’ work-related approach depending on their level of openness to change and task-innovativeness. The analysis ends with further research recommendations drawing on social psychology concepts enriched by management theories and applications.
