Summary

Organizations and jobs differ.While you may prefer either a behavior or a results-based approach，it may be inappropriate to use the same approach for all jobs.If，for example，we are evaluating social workers or teachers，we know that we can measure some results，such as number of cases closed or student scores on a standardized examination，but those results are due to some important factors beyond the employee's control—like the economy，family influences，and the health and abilities of individuals.In these situations，we might be better off using behaviors and making the inference that good job behaviors are going to contribute to desired results.And there is on reason a performance evaluation system for a given job cannot be a mixture of some results measures and some behavior scales.(https://www.daowen.com)
