Designing a Model of Competency for General Managers with the approach of the best subset regression

The application of the concept of competence is one of the latest methods in human resource management. Competency models are comprised of many skills that lead organizations to cope with problems in operation. The purpose of this study was to design a simple and practical competency model for general managers. The present study was carried out by using a crosssectional method and utilizing the results of 50 evaluation centers in an Iranian organization. For this purpose, 531 of the organization’s managers participated in a two-day assessment center and were evaluated by a comprehensive competency model with 24 dimensions. Of the scores of 531 people, 521 were used for modeling and the remaining 10 were used as the test set and proposed a method of validation. In order to simplify the initial model, the regression method was used to select the best subsets. The findings showed that the constraint on the determination coefficient is met when modeling is based on five independent variables. The findings of the validation also indicate that the values predicted are close to the actual values. The mean square error is 11. 97 and the mean absolute error is 2. 99. Therefore, based on the results, a simpler competency model that includes 5 accountability competency, effective communication, macroeconomics, negotiation and persuasion, and leadership effectiveness was introduced to the organization to use in their various Human Resources Management processes.
