Course objectives COURSE OBJECTIVES: This course introduces students to concepts and methods of modern statistical quality control. Students learn to apply standard quality control tools. They learn the theoretical statistical concepts that justify the use of particular quality control tools in particular situations. They learn theory and methods for analyzing the performance of different quality control tools. The use of appropriate software for statistical and quality analysis is taught, and is necessary for successful completion of some homework assignments. Issues of ethics and professional responsibility and their relation to product quality are discussed.

Contribution of course to meeting the professional component This course shows how to use modern statistical quality control tools, such as control charts and process capability measures, to monitor quality characteristics of manufacturing processes. Students also learn the underlying basic probability and statistics so that they will choose appropriate quality control tools and will be able to implement specialized tools for non-textbook situations, as well as to analyze the theoretical performance of those tools. The importance of product quality in the contemporary global economy and the relationship between quality and professional ethics are also discussed.

Relationship of course to program outcomes As shown in the BSIE Course Outcomes Matrix: a. Ability to apply knowledge of mathematics, science and engineering e. Ability to identify, formulate, and solve engineering problems f. Understanding of professional and ethical responsibility k. Ability to use the techniques, skills, and modern engineering tools necessary for engineering practice

Comments on outcomes a. Principles of probability and statistics and their appropriate application to quality engineering, including use of computer software. e. Through homeworks and computer projects, students learn to formulate and solve quality characteristic monitoring problems. f. Essay assignment and class discussion on relationship between product quality, public safety, liability, and professional ethics. k. Use of interactive PC - based computer programs for statistical analysis. MATLAB is introduced in class, students may also use Excel or specialized mathematical and statistical packages. Several homework assignments require use of computer tools for completion, all assignments are more easily completed with (strongly encouraged) computer use.

These outcomes are what students are expected to gain from this course.
