The competency-based selection system follows objectively stated criteria to determine whether a person has the necessary competencies required to arrive at exemplary work results. In contrast, the job analysis selection system works on accurately identifying the candidate with the highest potential to be a top performer.
The competency-based selection system works with the assumption that performance across all sectors in an organization should maintain a particular behavioral theme in the competencies directly connected to the organization's strategy. The job analysis selection system mainly focuses on a specific job without acknowledging that job behavior or requirements can be influenced by other factors rather than formal responsibilities and the prescribed job equipment.
The competency-based system gives a prescription on how work activities need to be carried out. Job analysis provides an objective depending on the routine work activities and the associated work requirements.
