A survey was conducted on selected sample of financial and administrative follow-up management. Results indicate that the independent variables; the organizational structure, the use of information and the performance evaluation have a significant correlation and are statistically influential on the effectiveness of financial and management control.

The technical approach such as the information technology system needs to be adequately structured. Human resource is the foundation factor in management thus it needs to be focused. Specific criteria or guidelines need to be addressed do that the evaluation on the theoretical aspects can also be applied to the evaluation on the practical aspects.
