PREFACE — The textbook was formerly titled Quality Control Eighth Edition. It is re-titled as — Quality Improvement Ninth Edition to reflect the concept of improvement rather than control.

This manual has been published to sim plify the instructor’s tasks tasks of developing learning activities and evaluating performance. performance. It is based on the experience of the author and is meant to serve as a guide. Each instructor will need to to modify this information information for the particular course objectives and the ability level of the students. For those teachers who are familiar with the Eighth the Eighth Edition of the textbook, information on the major changes to the Ninth the Ninth Edition is provided. provided. This information information should simplify simplify the transition to the latest edition. A typical course outline for a three-semester hour course is shown on Page 2. The learning activities are based on 45 class meetings of 50 minutes each. Since it is difficult for the average student to cover all of the material in a typical three-semester hour course, this outline concentrates on the basic statistical aspects of quality improvement. The instructor may wish to substitute Management and Planning Tools for Reliability. If a course in statistics is a prerequisite, the instructor may include Experimental Design and Taguchi’s Quality Engineering. Solutions for the problems start on Page 3. The author has found it advantageous to post the solutions. This action allows students to determine if their methods and answer are correct. Typical multiple-choice test questions are given and an asterisk indicates the correct answer. These questions can be modified in a number of ways depending on the creativity of the instructor. Answers to test problems are are also given. Since the tables in in the body of the text and in the Appendix are needed to solve the problems, an open-book type examination should be considered. The instructor may also also consider providing copies of the tables and using a closed-book format. Regardless, the multiple-choice multiple-choice questions can be given in the closed-book closed-book format. The author has found that allowing allowing the students 3x5 cards for formulas and other information is a great learning ex perience.
