Through the understanding of the change of productivity and the ability of error recovery according to aging and the assessment and analysis of them, we may take this research to contribute to make a design for the road-map to help set up the policy of employment for old generation. For this we have taken an experiment of the coordination tester for 100 person who are chosen randomly and analysed the collected data using SAS, which is one of widely used statistical analysis packages. The main results are as follow: $circledcirc$ The result of regression between the working speed and the length of the correction of error shows independence. (pr>0.2029). $circledcirc$ The regression between age and working speed is statistically significant. (pr<0.0001) $circledcirc$ The relation between age and the length of the correction of error is not significant. (pr>0.9123).
