Rule of 10
(past)(better)
An instrument or
gage should be 10 times more accurate than dimensional tolerances of the part
being measured. (A factor of 4 is known as the Mil Standard rule).
(Kalpakjian,
Smith; Manufacturing Engineering and Technology 4th Edition; pg.
961)
Rule of 10 (new)(group: measurement principle)
If there is a tolerance
on the objective quantity, the rule of 10 measurement principle says that the
finest resolution of the measurement system must be less than or equal to 1/10
of the tolerance. The measurement system must be reasonably simple and easy to
operate.

Donald W. Benbow, The certified six sigma black belt handbook, second edition, page
309)
Esteem Value (past)
Manufacturing adds value to
materials as they become discrete products and are marketed. Because this value
is added in individual stages during the creation of the product, the
utilization of value analysis is important.
Esteem value (prestige value)
reflects the attractiveness of the product that makes its ownership desirable.
(Kalpakjian S. & Schmid
S., Manufacturing Engineering and Technology, p.1266)
Esteem Value (new) (better) (group: accounting)
It is worth
spending a moment to consider what is meant by the term value. Value is a
concept which can be thought of in three ways:
Exchange value:
what a buyer will pay for a product;
Use value: what
the buyer will pay for the practical function which the product carries out;
Esteem value: the extra which the buyer will pay over
and above the use value
It is readily
seen that the first is the total of the other two. The way in which they
combine can vary dramatically. Consider two cars; one a Mercedes, the other a
Ford. The use value of each is more or less identical, but the esteem value of
one is far higher than that of the other. Thus the exchange values are markedly
different.

First-Time Manager: The First Steps to a Brilliant Management Career, Third
Edition, page 150)
Hundred-Percent Inspection (past)
When inspection is conducted
by humans, there is no guarantee that %100 of the defective parts will be
found; because of fatigue and boredom, human inspection is only 80-85%
effective.
(Schey John A., Introduction to Manufacturing Processes,
p.897)
Hundred-Percent Inspection (past) (better)
A Hundred
percent inspection is the inspection of every unit of product (procedure, data,
operations, etc.).In same cases of 100 percent inspection, the accepts rejects
decision will be made not for the entire lot, but for each unit individually, based
upon the results of inspection the unit for the quality characteristics
concerned. For critical quality characteristics 100 percent inspection or
inspection of relatively large samples is usually required to assure the
desired quality protection.
(John Langford, Logistics:
Principle and Applications, second edition, page 93)
Hundred-Percent Inspection (new) (group: quality
control)
100 percent inspection is
somewhat comparable to production line operation because each and every item is
subjected to it. One hundred percent inspection is required in certain highly critical
processes, and in processes that produce unavoidable defects, such as
semiconductor fabrication. However, both Deming and Juran point out that 100
percent inspection done by humans are usually only around 80 percent effective.
Thus in today’s industrial environment, 100 percent inspections are nearly
automated.
(Rober W. Berger, The Certified quality
engineer handbook, second edition, page 74)
Resolution (past)
Resolution, also
called sensitivity, is the smallest difference in dimension that the instrument
can detect or distinguish. A wooden yardstick, for example, has far less
sensitivity than finely graduated steel rule.
(Kalpakjian,
Smith; Manufacturing Engineering and Technology 4th Edition; pg.
946)
Resolution (new)
(better) (group: programming)
Whether
on the Web or a local application developed in Access, VB,C, or any other
platform, your users will have displays set to various resolutions.
This
means that, absent any adjustments by you inside your program, the forms you display
on the screen will appear either bigger or smaller than they do to you on your
machine. Whether bigger or smaller depends on whether the target machine’s
screen resolution is higher or lower than the screen resolution of the machine
on which the form was designed.
If
your form goes to a machine with a higher resolution, your form will shrink. If
it goes to a machine with a lower resolution, your form will appear larger.
