Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Procedure includes the following:

frequency of sample and sample size

Data includes the following:

periodic samples drawn from a trial run of the process

Process capability includes the following:

the natural tolerance of the process which may be calculated at 3 sigma/standard deviations

Product defects include the following:

from a consideration of 3 or 6 sigma standard deviations compared to specification requirements

Various options include one (1) or more of the following:

adjustment of process to move average

improvements to reduce process capability

changes to reduce assignable causes

Appropriate sampling plan includes one (1) or more of the following:

plans within the adopted quality system

frequency of sample
