On the basis of the results obtained by the control test was done in step 3, KTV conduct re-evaluation of risk control. If:Risk control as the original expectations or lower initial assessment, KTV can rely on KSNB system to conduct audits. When that KTV can perform a basic test in numbers equal to or less than initially expected when planning the audit.Control risk is assessed as high, i.e., not consistent with the level of risk control was originally scheduled (risks under the maximum level) or via control test is not obtained evidence of the effectiveness of the system, then KSNB KTV will not rely on KSNB system to reduce the basic test which must strengthen this experiment to search by sufficient and appropriate for the opinions of KTV.In the course of performing an audit, the KTV always update the characteristics of KSNB systems detect strengthen commenting on KSNB rating system was implemented. Suppose KTV a breach critical due to loose control procedures, the count on KSNB of items or the cycle it will be refused and KTV will conduct basic experiments with high level.
