Question: What Are Failure Costs?

How can external failure costs be reduced?

Reducing external failure costs usually depends on increased prevention of defects and appraisal of quality during manufacture.

Both of these may involve additional costs, but it is generally agreed that any increase in prevention and appraisal costs will be more than offset by decreases in failure costs..

Ca. Estimate the probability of failure (of the action or inaction)Pf. Estimate the cost of failure (direct and assured indirect costs)Cf. Multiply the probability times the cost of failure to get a risk cost.Rc=Pf x Cf. Compare the Cost of Action to the Risk Cost for a B/C ratio.BC=Rc/Ca.
