P-O model unifies enterprise goals and three important factors that affect employee performance: position analysis, performance evaluation and salary design;
Enterprise goal is the starting point of the design of human resource management system. Job analysis, performance appraisal and salary design are all aimed at providing strong support for the realization of enterprise goal through the optimization of human resource management system.
Post analysis provides the content and method of performance appraisal, and clarifies the salary difference between different positions.
The results of performance appraisal determine the performance salary of employees, and at the same time, the results of employee performance appraisal become an important reference for job analysis, job design and job change.
As an important feedback mechanism, salary can support the lasting and efficient operation of performance system, and the salary level and fairness of different positions affect employees' willingness to change jobs.
