Modeling the process of developing employee competencies and assessing their impact on an organization's performance is an urgent task. The study aims to develop a unified concept for modeling the process of employee competency development by implementing a corporate well-being program to achieve the workers' target KPIs. The study consisted of two stagesmodeling and a survey. A database on the components of the model is formed based on a survey of 727 individuals from different companies and economic sectors. The model is tested by means of preliminary analysis of the collected data, their clustering, assessment of interrelations of components, and systematization of the existing regularities. Fuzzy clustering of values, well-being elements, and individuals is constructed on multidimensional samples. Estimates of the probabilities of elements' transitions from clusters by values to clusters by activities and vice versa are obtained. The fuzzy clustering algorithm is developed in Python. The results show that for employees with a less pronounced value model, the well-being program in the company is of medium importance. Conversely, the well-being program in the company is of high importance for employees with prevailing social values. Employee clustering can suggest several propositions for the most efficient activities of the corporate well-being program according to the envisioned generalized employee value model. Conversely, it can help determine a candidate's optimal value profile for them to work effectively in the organization proceeding from the current corporate well-being program.
