6 Sigma Statistical Process Control (SPC) Software for Windows
Usually associated to geometric tolerances,
but should be applied to all parameters that are critical. (i.e.,
transistors, resistors, drop tests, etc.) This is a essential process
in any six sigma program.
Experiments that are carried out to ascertain all tolerances that have the
most effect on any action or reaction and how to modify the tolerances to
best reduce these actions or reactions at the lowest possible cost. An act
of developing an explanation for a productís performance from any given
set of desired actions or reactions on the product.
During the initial process design of all
the required components, one arranges components and associated component
tolerance parameters developed in an ongoing process so that one can then
make important improvements to the process. Associated with design
margins and statistical tolerances.
One of the steps in the Taguchi Approach to Design Optimization for
Quality and Cost.
