Overall Reliability
To complete the assessment the final task reliability or risk of error the chance of error and the opportunity
for recovery are categorised according the error risk matrix shown in Figure 5. In the example of the pipeline
inspection, the risk is judged as high because the PIF score is high combined with a moderate opportunity
for recovery.
