Presenting the Model of Aligning the Individual Development Program (IDP) with the Career Path, Based on the Foundation's data-theorizing Approach
Published 2025-03-01“…Also, since the success of the organization depends on the realization of the goals and needs of the individual and the organization in a balanced manner, and the methods proposed (individual development program and career path planning) each emphasize only one dimension (individual and organization), and it seems that the application of each alone will not lead to the realization of the desired results of the organization, And on the other hand, considering the studies conducted in the field and the lack of a comprehensive model that examines the individual's development plan in line with the needs of the organization, the results of this research will help organizations create a better fit between the job and the employee, ultimately leading to the efficiency and effectiveness of organizational activities.Case study The statistical population of this study consisted of 16 academic experts, scholars, and consultants in the field of human resources.Materials and Methods The sampling method for this research was non-probability and purposive, and data were collected using a semi-structured interview approach.Discussion and Results After conducting the initial semi-structured interviews, a set of initial themes was collected during the open coding process and categories were extracted from them; then, in the axial coding stage, the link between these categories was determined under the headings of causal conditions, axial phenomenon, strategies, contextual factors, intervening conditions, and consequences of aligning the individual development program with the career path in the form of the axial coding paradigm; and then, in the selective coding stage, the storyline was drawn and the initial model was calculated.ConclusionThe results showed that the causal factors for aligning the individual development program with the career path are: the necessity of job-employee fit, lack of structure in the learning and development process, speed of change, reduction in key organizational capabilities, and reduction in employee organizational belonging. …”
