This document discusses quality management and acceptance sampling. Acceptance sampling is a method used to accept or reject product batches based on random sampling. It has advantages like lower costs and handling compared to 100% inspection, but risks include potentially accepting bad batches or rejecting good ones. The document explains that acceptance sampling is used to make a decision to accept or reject a lot, not estimate overall quality. It outlines the concepts of producers' and consumers' risks and how sampling is used to determine if a process is within controlled limits for accepting or rejecting lots.

2. Quality Management :
• Quality management is focused not only
on product quality, but also mean to
achieve it. Quality management therefore
uses quality assurance and control of
processes as well as products to achieve
more consistent quality.

3. What is acceptance sampling?
• Acceptance sampling is a method used to
accept or reject product based on a random
sample of the product.
• The purpose of acceptance sampling is to
sentence lots (accept or reject) rather than to
estimate the quality of a lot.

4. What is acceptance sampling?
• Purposes
–Determine the quality level of an
incoming shipment or, at the end
production
–Ensure that the quality level is within the
level that has been predetermined

5. Acceptance sampling advantages
– Less handling damages
– Fewer inspectors to put
on payroll
– 100% inspection costs
are to high
– 100% testing would
take to long

6. Acceptance sampling disadvantages.
–Risk included in chance of bad lot
“acceptance” and good lot “rejection”
–Sample taken provides less information
than 100% inspection

7. Acceptance sampling explained :
• Consumers risk
– Receive shipment, assume good quality,
actually bad quality
• Alpha
– Type I error(producers risk)
• Beta
– Type II error(consumers risk)

8. How acceptance sampling works.
• Remember
–You are not measuring the quality of the
lot, but, you are to sentence the lot to
either reject or accept it

9. How acceptance sampling works.
• Acceptance sampling is used by
organizations to determine if there
process’s are running within a
controlled limit and to see if they
should reject or accept lots
