d. Failure Mode and Effect Analysis

d. Failure Mode and Effect Analysis

Services are largely intangible, while physical products are tangible goods produced by manufacturing operations. (T/F)

True

A company typically incorporates serviceability late in the design phase to consider customers' evaluation on the work-like prototype. ( T/F )

False

Too high reliability will cause warranty and repair costs to be high and therefore market share will be lost. ( T/F )

False

Too low reliability will cause the product to be too expensive. ( T/F )

False

Soft types of failure modes can degrade the performance of products. ( T/F )

True

Reliability is the probability that a product will continue to work normally over a specified interval of time, under specified conditions. ( T/F )

True

In general, it is shown that the highest failure rates correspond to premature failure and to end-of life wear out. ( T /F)

True

Type 1 controls prevent cause or failure mode from occurring, or reduce rate of occurrence. ( T/F )

True

Type 2 controls detect failure mode before product reaches customer. ( T/F )

False

Type 3 controls detect cause of failure mode and lead to corrective action. ( T/F )

False

( _____________ ) is the elimination (or avoidance) process of failure modes and mistakes

Reliability

( ___________ ) is the occupation or function of serving to perform any of the business functions auxiliary to production or distribution.

Service

( __________ ) is the average time to repair.

MTTR

( _______________ ) is the manner in which a component or system failure occurs.

Failure mode

Detection values are associated with type of ( ________ ) and the detection is a measure of Type 2 ( ________ ) to detect causes of failure, or ability of Type 3 ( __________ ) to detect subsequent failure modes.
