COURSE OBJECTIVES This course will present the theory and methods of quality monitoring including process capability, control charts, acceptance sampling, quality engineering, and quality design. The objectives include
• To understand the basic concepts of quality monitoring. • To understand the statistical underpinnings of quality monitoring. • To learn various available statistical tools of quality monitoring. • To learn the statistical and economical design issues associated with the
monitoring tools. • To demonstrate the ability to design and implement these tools.

C+: [70, 75]; C: [65, 70); C-: [60, 65); D: [50, 60); F: <50 PROJECT will be due on Monday, November 25.



Please form a team of three or four. In the final project report, all team members should sign and

state that they contribute to their project roughly equally. Every member will receive the same

grade on the project.

All reports should be typewritten and printed out for handing in. The report should not exceed 8 pages. (12 point, double space, Appendix does not count to 8 pages.) The report must have a

professional appearance. Clarity and thoroughness of the analysis, and good use of the English language, including grammar, spelling and punctuation, are considered in grading the project.

Final project report includes project objective, problem statement, solutions, conclusions, and appendix if needed. The report should describe the background, any assumptions made, the analysis used to analyze the data, and the appropriate results. Explanation, interpretation, and justifications are required. Computer output should be included in an appendix and the description of the outcome/results included in the text of the report.

Sample Class Projects:

Example 1: IPod Nano Nike Plus System Capability Analysis: The team used IPod Nano to measure the distance and time of runs and analyze the capability (repeatability and reproducibility) of the device’s pedometer.

Example 2: Heart Failure Discharge Rate Analysis for Medicare Patients: The team collected data on the discharge rate of Medicare patients with heat failure in US. They aims to test the hypothesis whether there is a statistically significant decrease in discharge rate and which states does this have the impact on.

Example 3: Monitoring energy use: The team aims to monitor and analyze the energy usage for an industrial pump at a Pulp and Paper plant. By monitoring baseline energy usage, the team will determine whether the pump is within nameplate specifications and then decide if energy-saving component is needed.



• Grading is purely based on the merit of your work. Request of credit or higher grade for

other reasons will NOT be considered.

• Assigned homework will be collected in class. Homework is due one week after it is

assigned. No late homework will be accepted.

• Cellphones are not allowed during exams.

• Exams can be taken on or before the scheduled exam dates with justifiable reasons.

• Exams will be closed book, closed notes. One 8 ½ x 11 formula sheet can be used. Be

sure to bring your calculator. There will be ABSOLUTELY NO SHARING among

students of books, formula sheets, or calculators.

• If you believe there was an error in the grading of an exam or homework, then you can

submit the entire exam to the TA requesting a regrade. This must be done within one

week from the date the exam was returned. The entire exam will be regraded, so that you

may gain, or lose, points by resubmitting.

• Students are responsible for all information conveyed during class and on Blackboard. It

is the student’s responsibility to make sure they are receiving their official USC email.

• Always bring your textbook to class! Also bring your calculator, notebook, pencils/pens,

eraser, and course syllabus.



The course will use Blackboard: You can also use smartphone app Bb

MobileLearn to access Blackboard.
