Mr. Miche?l O'Mahony:

The tool is a control tool that adds some assurances. For example, it manages the risk of fish being put over the weighbridge without the flow belt even being turned on. It manages the risk if we can see the flow belt moving and the clock clocking up. However, there are risks that the tool does not manage, such as that of the flow belt under-weighing, whereby a kilogram does not come up as a kilogram. The tool affords some assurances but, as with all controls tools, it does not provide assurance in the order of 100%. The tools help but are not in themselves a 100% solution.
