Rational Subgrouping
|
Choosing the correct subgrouping scheme is critical
to the proper analysis of a Shewhart chart. An improper
subgrouping rationale can hide process changes or indicate
process changes where in actuality none exist.
The wrong subgrouping scheme can render a chart useless
or worse.

| Act Now to Process Changes |
|
In order to truly make process improvements,
you must investigate, take action, and document when nonconformities
or non-normal variation are detected in your processes.
A key element in achieving this operational excellence
is to identify the sources of variation that affect your
process, product or service. Once identified, these key
sources can then be earmarked for attention.

| Quality Q&A: Normal Probability
Plot Interpretation |
Q: How do I use a normal probability
plot to assess the normality of a population?
A: Probability plotting is a graphical
method for determinig whether sample data conform to
a hypothesized distribution, based on a subjective visual
examination of the data. In process management, we are
typically concerned about whether the data is distributed
according to a normal distribution, since many of the
statistical inference procedures that we use require
the assumption of normality of the data.
