ST 515: Spring Semester

Statistical Science & Process Improvement

Objective: To provide a course in which graduate students from many disciplines can discuss the role of statistical science in improvement of products, services, and operations. Students will learn the basics of the management changes that are necessary to move toward Continuous Improvement and how statistical science is involved. Practical examples from the instructor's experience will illustrate the concepts. However, it is expected that the semester project will be the principle tool for learning.

Instructor: Professor Tom Boardman, Statistics Dept., Colorado State University, Fort Collins, CO 80523-1877; (970) 491-5721 (with voice mail); Fax (970) 491 -7895; email address is boardman@lamar.colostate.edu; homepage at http://www.stat.colostate.edu/~boardman/

Prerequisites: ST511 or other first course. or permission of instructor

Credits: 3 available for Distance Learning.

Meeting day, time and room: T,R from 11AM-1PM in E202 Engineering Building

Office Hours: TBA

Text:

Workbook for Quality Improvement and Statistical Thinking, Edition 2.2 2000, by Thomas J. Boardman and Eileen C. Boardman, Boardman Associates, Fort Collins, Colorado (Available for ST515 students only at CSU Bookstore, printed by Kinkos.) Chapter III and IV will be deleted to lower cost.

Computer Package: While many packages offer the analyses we will need for this class, Minitab Version 12 is the one we will show in class.

Other texts:

These texts are supplemental and not required. Interested students may wish to study these at the reserve desk in Morgan Library:

Statistics for Experimenters by G.E.P. Box , William Hunter and J. Stuart Hunter, John Wiley & Sons, NY

Understanding SPC, 2nd, by Donald Wheeler and David Chambers, SPC Press Knoxville, TN 37919; (615) 584-5005

Format of Course: Session on Tuesdays and Thursdays will include both lecture and a Discussion/Q&A/Lab format which will vary in content each session. The instructor's computer presentations will use MS Powerpoint with most slides from the Workbook. Minitab and other packages will be used in class to help with the learning.

Projects: These will be due during the finals week. Each student team will be asked to make an oral presentation and submit an written report during the week of finals. Distance Degree students may join our class, if possible, or prepare another suitable format (video, video-conference, etc.) for the oral presentation.

Notes: The actually order of the topics may change as we see how we are doing. The intent is not to rush the learning process. Where "+" is shown under References either addition materials for our Workbook will be available or additional reading assignments will be made.

Course "policies:"

Students are expected to have an "email" account and to use it regularly. Accounts will be provided on lamar for all students.

Reading assignments in the Workbook and elsewhere will be made. These may include readings on topics not fully discussed in class.

Homework assignments will be made throughout the semester and are due as noted during the class they are assigned (usually Thursdays). Special circumstances will be considered with understanding. Students are encouraged to work together or seek outside input on these assignments, if desired. These are an important way to "learn" the material covered in class. I expect these to be turned in at the dates indicated in class.

The course project will be due at the end of the semester.

Examinations, when needed, will be of the open book, take home variety. Except as stated, students are expected to work on their own on these "exams."

Grades will be based on accomplishments on the homework and project (and possibly examinations). If no exams are needed approximately half of the grade will be based on homework performance and half on the semester project.
