control refers to the process, most often implemented in manufacturing, of
monitoring the quality of finished products through measures and an overall
corporate commitment to producing defect-free products.
QA V.S QC
• Quality
control and quality assurance are important concepts, yet most project managers
have only a vague understanding of the meanings and the differences between
these terms.
• Quality
Control refers to quality related activities associated with the creation of
project deliverables. Quality control is used to verify that deliverables are
of acceptable quality and that they are complete and correct. Examples of
quality control activities include deliverable peer reviews and the testing
process.
Quality Assurance
• Examples
of quality assurance include process checklists and project audits as well.
• The
auditor being able to tell if the deliverable seems acceptable based on the
process used to create it (quality assurance).
Quality Control
• Examples
of quality control activities include deliverable peer reviews and the testing
process too.
• If
your project gets audited, for instance, an auditor might not be able to tell
if the content of a specific deliverable is acceptable (quality control).

• Quality
Assurance is the process that no matter the complex the program; defects can be
easily fixed to ensure quality later when truly Quality should be designed into
the product.
• QA
usually takes close to 35 % of the Project Process time between testing and
reviewing.
• The
terms “quality assurance” and “quality control” are often used to refer to ways
of ensuring the quality of a service or product. The terms, however, have
different meanings
• Assurance:
The act of giving confidence, the state of being certain or the act of making
certain.
• Control:
An evaluation to indicate needed corrective responses; the act of guiding a
process in which variability is attributable to a constant system of chance
causes.
• The
cost of quality.”
• The
“cost of quality” isn’t the price of creating a quality product or
service. It’s the cost of NOT creating a quality product or service.
• Quality
control managers are responsible for maintaining the quality and reliability of
products and services. Quality control managers inspect and test products at
various stages in the production process.

• The
Major Difference is Quality control activities are focused on the deliverable
itself. Quality assurance activities are focused on the process used to create
the deliverable. They are both powerful techniques and both must be performed
to ensure that the deliverables meet your customers quality requirements.
