Standard ISO 45001 defines “Effectiveness” as “extent to which planned activities are realized and planned results achieved”.
Effectiveness is an important concept in ISO management systems like ISO 9001, ISO 14001, ISO 50001, ISO 45001 & other management system standards. Due to this concept the number of actions taken are verified in reality and the impact of actions are monitored.
Why is there a need to measure effectiveness? It is possible that the root cause of a non-conformity is defined incorrectly and the analysis is erroneous. Therefore the corresponding corrective action based on the root cause will also be wrong. Thus corrective action will not prevent the nonconformity occurring again. Therefore it is through Effectiveness analysis, a wrong corrective action and wrong root cause can be identified and evaluated and thus corrected.
Examine which document of non-conformity and corrective action require effectiveness.
Effectiveness analysis of actions taken is also applied on actions taken to achieve OH&S objectives. Effectiveness check is actually a performance evaluation tool for the corrective actions taken.
