3.  This may be defined as measures put in place in
order to ensure that the product meets the customer
expectations
 Those planned and systematic actions which provides
a mean to control and measure the characteristics of
a product, process or a service to established
requirements
 Quality control monitors not only the product itself,
but the way it is produced,stored and transported
What is Quality Control?

4. The manufacturing process is a repetitive process
depending on both controllable and non controllable
factors resulting in the deviation of the quality of the
product.
Quality control is the vital process for verification or
correction of the quality of the product whenever the
deviations are found to be more than expected.
Why is Quality Control Important?

Types Of Quality Control

6. 1. Internal Quality Control
When a company institutes protocol to check their system,
this is called internal quality control. This can range from
routine checking of equipment, having a co-worker go over
another employee's data analysis, or running standards
and controls on a regular basis. It is generally up to
management to decide if internal quality control measures
are reliable and performed as needed

2. External Quality Control
This is when data or products are sent to an independent
body from the company e.g., sending food to the Food
and Drug administration.

8. Types Of Quality Control
3. Proficiency Testing Quality Control
A special type of quality control often done on a volunteer basis or
to gain accreditation is proficiency testing. In this type of quality
control, the company is sent a series of tests to perform. The
results are sent back and the company receives a grade on its
proficiency. This type of testing is often done in laboratories,
where sensitive equipment and complex protocols need to be
verified as accurate before the lab is allowed to continue its work.

9. The ISO standard defined inspection as the activity of
measuring, examining, testing one or more
characteristics of the product/service and comparing
the results with the specified requirements in order
to establish whether conformity is achieved for each
characteristic.
This task is usually performed by specialized
personnel and does not fall within the responsibility
of production workers.
Products that do not comply within the specifications
are rejected or returned for improvement.
What is Quality Inspection?

10. These are tools used by inspectors to ensure that all the products
manufactured by the company are within the limits designated by
the designers/producers.
Examples of such tools include:
1. Air gages (inside and outside diameter, to look for leaks)
2. Bore gages (to measure dimensions)
3. Calipers (slide movement)
4. Color sensors (determine the proper color mixture of clothing or textile)
5. Biological Microscopes (to study organisms and their vital processes)
6. Electron Microscopes (to produce smaller scale images of the product)
7. 3-D scanners
