Effectiveness measurement, safety decision hierarchy

Although a hazard analysis and a risk assessment would result from applying the preceding outline, good management requires that the remaining steps in The Safety Decision Hierarchy be taken, which are—decide and take action, and measure for effectiveness. 

Develop Remediation Proposals. When the results of the risk assessment indicate that risk elimination or reduction measures are to be taken, alternate proposals for the design and operational changes necessary to achieve an acceptable risk level would be recommended. In their order of effectiveness, the actions as shown in Chapter 12, Hierarchy of Controls The Safety Decision Hierarchy, would be the basis on which remedial proposals are made. For each proposal, the remediation cost would be determined and an estimate of its effectiveness in achieving risk reduction given. Risk elimination or reduction methods would then be selected and implemented. 

Provisions in Section 7.1 of ZIO, Management Review Process, require that systems be in place to measure the effectiveness of the risk reduction measures taken. Those provisions are relative to the measurement of effectiveness and re-analyzing steps in The Safety Decision Hierarchy. Assuring that the actions taken accomplish what was intended is an integral step in the PDCA process. Followup activity would determine that the ...
