***Introduction to Statistical Quality Control*, Seventh Edition, Montgomery,
D.C., Wiley.

**Grades: **Grades will be determined in the
following fashion. There will be two midterms. Each midterm is worth 100 points
and homework will be worth 50 points. There will be a group project worth 40
points. There will be 10 points given to students who fill out the online
course evaluation. Your grade will be determined out of your total of 300
points.

**Exams: **__Exams are based primarily on lecture material and designated
reading material__. __You are
responsible for what is discussed in class__. All exams are closed book,
closed notes. I have created two hyperlinks to folders entitled “Older SPC
Exams” and “Recent SPC Exams”. Due to the change in textbook, they can be
useful on some topics but not a reliable guide for coming exams. While exam
questions vary in difficulty, the answers are generally quite brief given the
time constraints on the exams.

**Software**: You are
free to use any software package you wish, but I recommend **JMP**. Help with statistical software packages is available at the
help desk** **in **MATH G175.** **JMP**, which is popular in Industry, is
available in all ITaP labs and can be used remotely. **JMP **is also free to students. You can check out a copy from ITaP by
going to STEW G31 (the location used to be in YONG). You can check out a copy
overnight to load onto your laptop or desktop. It’s very good for preparing
presentations. **R** software is open
source (i.e. free) and the Program “qcc” in R will do
most of the necessary control charts.

**HW: **HW is to be uploaded to
Blackboard by 5 p.m. the date due**. **Note:
individual homework will be graded out of 100 points (i.e. a percent). At the
end of the semester they will be averaged to give an average percent score on
HW, this will determine your percent of the 50 point total for HW**. **Late HW is ½ off.

**Course
Evaluations: **

Send a copy
of the form which states you have completed the course evaluation to the
grader. There have been problems with evaluations sent to students going
directly to their junk mail folders. Students should log on to the evaluation
site by visiting www.purdue.edu/eval
to fill out course evaluations.

**
** ** Course Objectives: **To
become fluent in the language and techniques of modern Quality Control and its
applications. While areas of application are typically thought of as being in
the area of manufacturing, (including processes related to ordering,
accounting, record keeping and customer satisfaction) principles of Quality
management are applicable to all types of organizations. These areas include:
Health Care, Service Industry, Pharmaceutical, Education (at all levels),
Non-Profit, Small Business, Software Reliability, etc.

** Course Topics:**

1. Basic concepts.

2. Basic probability.

3. Summarizing Data.

4. Basic Tools
(flowcharts, fishbone diagrams, Pareto charts).

5. More Advanced Tools
(process flow diagrams, Cause and Effect Matrices)

6. FMEA: Failure Modes
and Effects Analysis

7. Shewhart Control Charts.

8. Facts about Control
Charts.

9. Effective use of
Control Charts.

10. Control Charts for
Attribute Data.

11. Effective use of
Attribute Data.

12. Capability.

13. Use of Control Charts
for Continual Improvement.

14. Topics for
Measurement Charts.

15. Acceptance Sampling
(and why it’s a bad thing to rely on).

16. Six Sigma and DMAIC.

17. Experimental Design,
Taguchi Methodology and Alternatives.

18. ISO and WTO.

**Other
Reading: **

** **1. *Understanding
Variation-the Key to Managing Chaos*, by Donald J. Wheeler. SPC Press, ISBN
0- 945320-35-3. If you are teaching an in-house course to people and they know
zip, this is really good for a business setting. Short, concise, to the point.

2. *Implementing Six Sigma*, by Forrest W. Breyfogle III. John Wiley and Sons, ISBN 0-471-29659-7. An
absolute must reference for the Six Sigma afficianado.
Well written, very detailed (~700 pages) but well organized so special topics
are easy to find. The first third, or so, is written to be very accessible to
anyone who is literate in Quality thinking but wants to get a framework for Six
Sigma thinking. The last two thirds are mainly technical statistical topics
used in Six Sigma implementation and require a fairly good background in
statistics, but also well written.

3. *Lean Manufacturing-Tools, Techniques and How
to Use Them*, by William M. Feld. St. Lucie Press, ISBN 1-57444-297-X.
Concise and to the point (lean, so to speak J). I never could
figure out a good definition of “lean”, but to borrow a euphemism from a U.S.
Supreme Court ruling “You can’t define it, but you know it when you see it.”.

4. *What is Six Sigma, *Pande,
P. and Holpe, L.. McGraw
Hill, IBSN: 0-07-141270-0. An excellent primer for someone with a basic
knowledge of SPC. Many in Industry use it as a primer for new hires.
