Difference in responsibilities
Quality Assurance Quality Control
Evaluates whether quality
control is working for the
purpose of determining
weakness in the process.
Evaluates if the application
is working for the purpose
of determining defect in
the functionalities.
Improves the process that
is applied to multiple
products.
Improves the development
of a specific product or
service.QA personnel should not
