| Using p Charts to Solve a Steel Mill
Quality Problem |
|
by Marilyn & Robert Hart
A steel mill quality problem
arose in the manufacture of cold-rolled steel for use in
applications such as automobile hoods. In order to form
a long continuous band, several hot-rolled coils were welded
together end-to-end. The long continuous band then included
the welds that were made to join the original coils together.
Unfortunately, many of these welds were failing under tension,
causing damage as well as extreme danger as these coils
then flailed about.

| Producing Consistent Reports &
Bringing Reports
to the Organization
|
Often, our customers would like to access Statit
e-QC reports without actually having to log in to the
application. And those creating reports could use
some help in producing a consistent structure to their
reports. This article covers some features of Statit e-QC
that may be very helpful to you. The first two features
involve deployment of your reports, while the third makes
it easy for the report writers to create content that
is consistent.
Many of our customers want to make the Statit e-QC
dynamic reports more accessible to users. Often
customers have intranet sites or corporate portals which
their employees use to access a wealth of information.
In cases like this, it is inconvenient for many users
to remember that some of that information is in Statit
e-QC or that they need to log into Statit e-QC to access
certain quality reporting or information.
With Statit e-QC, these dynamic reports can be
made available to the intranet user. There are two
report types that users can utilize to provide this capability.

| Continuous Quality Improvement Dashboards—What's
the Big Deal? |
The whole Performance Improvement
or Continuous Quality Management dashboard space has been
gaining significant traction lately as more and more organizations
are recognizing the need to monitor their business performance
and proactively make strategic and tactical decisions
rather than becoming reactive to situations.
The mantra for quality improvement
can be categorized into one simple statement: predictable
quality at a predictable cost. With so many dashboards
available today, what's the big deal? All reporting platforms
provide us with the needed information to "predict quality."
Pick one and you're good to go...right?
Not so fast...

| Quality Q&A: Non-Normal Effects
on Cpk |
Q. How will lack of normality affect my Cpk statistics
for a process? Will the calculated statistics be higher
or lower than they should be?
A. There is no one answer to this question. It
depends on how different from normal the distribution is,
whether the distribution is skewed to one side, how close
to a specification the distribution is, and other considerations.
Even moderate departures from normality that affect the
tails of the process distribution may severely impact the
validity of the process capability calculations.

| Process Capability for Normal
& Non-Normal Distributions |
 |
In
this complimentary webinar,
Guy March, Vice President of Professional Services for
Statit Software, will discuss the importance, application
and calculation of several of the process indices such
as Cpk and Ppk. Process capability
indices help the quality professional and engineer to
understand the relation of the voice of the customer to
the in-control process. Understanding the principles and
calculations behind the indices helps to properly apply
them. Near normal distributions are required for standard
process capability calculations, but often data are so
heavily skewed that these calculations are ineffective.
An analysis will also be presented for non-normal distributions
using Statit e-QC.
By attending this webcast, you will:
- Learn the principles and calculation of several
of the process indices
- Understand how the voice of the customer relates
to in-control process
- Hear firsthand about analysis for non-normal distributions
- See how customers are using process indices dashboards
for monitory and control
