Acceptance Sampling for Quality Control
taught by Galit Shmueli
Brief Description:
This course will cover acceptance sampling to determine whether to accept or reject a particular lot of a product -- how to determine sample size, and how make accept/reject decisions.
Instructor(s):Level: intermediate
Who Should Take This Course:
This course will benefit quality engineers and, quality inspectors and other quality control personnel who employ or supervise inspection plans at their organization, as well as quality assurance staff in charge of setting quality standards. Six Sigma black belts and trainers can also benefit from this course.
Dates:April 19, 2013 to May 17, 2013

Acceptance Sampling for Quality Control
taught by Galit Shmueli
Aim of Course:
Sampling plans are used in industry world-wide as a means of assisting quality assurance personnel to decide whether to accept or reject lots of products presented for inspection. Many organizations require the use of ISO standards for assuring the quality of incoming (or outgoing) batches of goods. The standards provide inspectors with information on the size of sample to be selected and a set of rules and procedures, which enables the inspector, having examined the sample, to decide on the acceptance or rejection of the lot. Based on statistical principles, sampling standards provide organisations with an effective and cost efficient means of selecting sample sizes and devising sampling plans.
In this course, participants will become familiar with popular sampling inspection plans for attribute data, measurement data, and continuous processes. They will understand the statistical logic behind ISO inspection plans and learn how to use the standards, and how to choose and employ such plans judiciously. The course will also introduce participants to a convenient interactive Web resource for obtaining standard inspection plans.

Homework in this course consists of short answer questions to test concepts and guided data analysis problems using software.
This course takes place over the internet at the Institute for 4 weeks. During each course week, you participate at times of your own choosing - there are no set times when you must be online. Course participants will be given access to a private discussion board. In class discussions led by the instructor, you can post questions, seek clarification, and interact with your fellow students and the instructor.
The course typically requires 15 hours per week. At the beginning of each week, you receive the relevant material, in addition to answers to exercises from the previous session. During the week, you are expected to go over the course materials, work through exercises, and submit answers. Discussion among participants is encouraged. The instructor will provide answers and comments, and at the end of the week, you will receive individual feedback on your homework answers.
Credit:
Students come to the Institute for a variety of reasons. As you begin the course, you will be asked to specify your category:
- You may be interested only in learning the material presented, and not be concerned with grades or a record of completion.
- You may be enrolled in PASS (Programs in Analytics and Statistical Studies) that requires demonstration of proficiency in the subject, in which case your work will be assessed for a grade.
- You may require a "Record of Course Completion," along with professional development credit in the form of Continuing Education Units (CEU's). For those successfully completing the course, 5.0 CEU's and a record of course completion will be issued by The Institute, upon request.
Course Text:
The text, Practical Acceptance Sampling: A Hands On Guide (2nd Edition) , is available both in both eBook format and print format at Amazon.
The main software used will be the online tables and calculators at www.SQCOnline.com. Simple computations for the course can be handled using Microsoft Excel, or other general purpose statistical software. This course does not require the use of specialized software capabilities such as those found in Minitab, JMP and Statgraphics. Click here for a complete list of statistical software.
