Relation between Cost and Reliability

These costs occur when

products or services fail to

reach designed standards and

are detected before transfer

to the consumer takes place

These costs occur when

products or services fail to

reach design quality standards

and are not detected until after

transfer to the consumer.

If specified reliability is lower

than optimum, the actual

costs to the consumer may

be high due to excessive

rapairs and maintenance.

If specified reliability is higher

then optimum, the actual costs

rises due to greater and stricter

requirements for components and

assemblies.
