Quick Quiz
1-80. Compared to a standard parts program, a standardization program places a great emphasis on which of the following?
(A) limited part numbers
(B) limited sizes
(C) limited suppliers
(D) limited part versatility
(B) limited sizes
The key here is the difference of the words “standard” which means common or known, and “standardization”, implies calibration, normalization or consistency. In context of this question the best response is (B) limited sizes. The benefit of such a program is few items to source, stock and monitor. This program improves reliability by reducing assembly errors and by having more time (few parts to evaluate) for reliability evaluations.
Limiting part numbers or vendors may also enhance reliability performance in a similar fashion and builds on the ability of the team to use components with a known reliability performance track record.
