Engineering Statistics II

Six Sigma and Quality Control

)

Course Objectives:

1. Students will understand the definition of quality.

2. Students will understand the Six Sigma Quality System and DMAIC approach for quality

improvement.

3. Students will understand how the tolerance of a part is determined and be able to

calculate assembly tolerances when several parts are assembled.

4. Students will be able to conduct a Design or Process Failure Mode and Effect Analysis

(FMEA) to reduce the effect of product or process failure.

5. Students will be able to construct variable, attribute and individual control charts to

monitor process stability.

6. Students will be able to evaluate the capability of a production process.

7. Students will be able to conduct a measurement system analysis to determine the

adequacy of the measurement system used for quality improvement.

8. Students will be able to use acceptance sampling plans (American Military Standards

MIL-STD) to determine if shipments from suppliers should be accepted.

9. Students will understand the development of various quality management systems such

as TQM, ISO, etc.

10. Students will be able to apply the concepts and methods learned in this class to evaluate

the quality of a production or service system using real world data.

HOMEWORK POLICY: Homework is due before the stated due date/time and has to be uploaded to

Moodle. Late homework assignments are normally unacceptable. In rare occasions, I would accept late

homework submissions via e-mail if proper excuses (for example, a doctor visit note or a proof of

traveling with no internet connection) are provided. However, no late homework will be accepted once

homework solutions are posted.

CELLULAR PHONE: Cellular phone must be turned off during the class period. If your

cellular phone rings when the lecture is in progression, you need to invite Dr. Ker for a lunch. .

The invitation will be upgraded to a dinner meal for second violations and beyond.

STUDENTS NEEDING SPECIAL ACCOMMODATIONS: Students needing testing

accommodations or classroom accommodations based on a disability are encouraged to discuss

the need with your instructor as soon as possible.

GRADE APPEAL: Students should confer with the course instructor first in the event of a

question regarding the final grade received. If unsatisfied with the results of the conference,

then, students may further appeal the grade following the procedure listed in University Policy

2217- Final Grade and Academic Appeals Procedure:

http://www.latech.edu/administration/policies-and-procedures/2217.php

HONOR CODE: Students should be aware that "during an exam, referring to information not

specifically allowed by the instructor or receiving information from another student or another

unauthorized source" is a violation of the honor code and can be met with severe sanctions

against the student. For details refer to http://www.latech.edu/tech/students/honor-code.pdf.

EMERGENCY NOTIFICATION SYSTEM (ENS): All Louisiana Tech Students are strongly

encouraged to enroll and update their contact information in the ENS. For more information on

the system, please visit: http://www.latech.edu/administration/ens.shtml
