Quality control (QC) and quality assurance (QA) are two important aspects of the Service Industry and the manufacturing process that is critical to ensuring that products and Services meet the desired quality standards. While both terms may seem similar, they are quite distinct from each other in terms of their goals, methods, and scope.
What is Quality Control (QC)?
Quality control is a process that involves monitoring and
inspecting the products during the production process to identify and eliminate
defects or issues. Its primary objective is to ensure that the product meets
the desired quality standards and that it is free from any defects or errors.
QC is generally performed by a team of quality control
professionals who are responsible for conducting various tests and inspections
on the product at different stages of the Service and manufacturing process. They may
use various techniques such as statistical process control, sampling methods,
and other quality control tools to identify defects and errors.
The main goal of QC is to identify and eliminate defects
before the product is shipped to the customer or the service is delivered to a
customer. By doing so, it helps to minimize the number of customer complaints
and returns, which in turn, reduces the cost of rework and improves customer
satisfaction.
What is Quality Assurance (QA)?
Quality assurance is a process that involves ensuring that
the entire manufacturing process is designed and implemented in such a way that
it meets the desired quality standards. Its primary objective is to prevent defects
and errors from occurring in the first place.
QA is generally performed by a team of quality assurance
professionals who are responsible for developing and implementing various
quality control procedures and standards throughout the entire Services and manufacturing
process. They may use various techniques such as quality planning, quality
audits, and quality management systems to ensure that the process is designed
to meet the desired quality standards.
The main goal of QA is to prevent defects from occurring in the
first place by ensuring that the process is designed and implemented in such a
way that it is capable of meeting the desired quality standards. By doing so,
it helps to minimize the number of defects and errors, which in turn, reduces
the cost of rework and improves customer satisfaction.
What is the difference between Quality Control and Quality
Assurance?
The main difference between QC and QA lies in their scope
and focus. While QC is focused on identifying and eliminating defects in the
product, QA is focused on preventing defects from occurring in the first place
by ensuring that the entire manufacturing process is designed and implemented
in such a way that it meets the desired quality standards.
Another difference between QC and QA is their approach. QC is reactive in nature, which means that it identifies and eliminates defects after they have occurred. On the other hand, QA is proactive in nature, which means that it focuses on preventing defects from occurring in the first place.
Furthermore, QC is typically performed by a separate team of
quality control professionals who are responsible for conducting various tests
and inspections on the product. In contrast, QA is typically performed by a
team of quality assurance professionals who are responsible for developing and
implementing various quality control procedures and standards throughout the
entire manufacturing process.
Thanks for sharing this Satheesh. I have been meditating for a longtime to understand the difference between Quality Assurance and Quality Control. Now I understand the difference.
