Walter Shewhart's 1924 1-page memo to his boss at Bell Telephone
included the first control chart, and outlined a way of
distinguishing "assignable causes" from chance variation
(signal from noise). Next month is the 120th anniversary
of Shewhart's birth, and while his classic SPC charts are
still in wide use, refinements with superior statistical
properties have now also accumulated some history. Dr.Tom Ryan
(also a pioneer in this field) will cover these improvements in
his online course “Advanced Statistical Process Control”
March 18 – April 8 at statistics.com.
This course presents cumulative sum (CUSUM) procedures and
exponentially weighted average (EWMA) methods and their
variations for monitoring processes. Although Shewhart control
charts are very useful and have been used for decades, CUSUM and
EWMA methods have also been used for decades and do have better
statistical properties than do Shewhart charts. After taking this
course, students will know how to implement and interpret control
charts using these two methods.
Thomas P. Ryan is the author of “Statistical Methods for Quality
Improvement,” “Modern Engineering Statistics,” “Modern Experimental
Design,” and “Modern Regression Methods,” all from Wiley, plus
numerous papers in peer-reviewed journals. He is an elected
Fellow of the American Statistical Association, American Society
for Quality, and Royal Statistical Society, and served on the
Editorial Review Board of the “Journal of Quality Technology” from
1990 through 2006 and was the Book Review Editor of that journal
from 2003 through 2006.
Participants can ask questions and exchange comments with Dr. Ryan
via a private discussion board throughout the period. There are no
set hours when you must be online, and you can work with the
instructor over a period of 3 weeks via a private discussion
board. We estimate you will need about 15 hours per week.
