Quality assurance vs quality control

2.  Quality Assurance: The planned and systematic activities
implemented in a quality system so that quality requirements
for a product or service will be fulfilled.
 This is process oriented and focuses on defect prevention
 Proactive
 Planning stage
 Managerial tool

3.  Quality Control: The observation techniques and activities
used to fulfill requirements for quality.
 Product oriented and focuses on defect identification.
 Reactive
 Execution stage
 Corrective tool

5.  Quality Assurance is to improve development and test
processes so that defects do not arise when the product is
being developed.
 Quality control is to identify defects after a product is
developed and before it is released.

6.  Quality assurance : everyone in the team involved in
developing the product is responsible for Quality assurance.
 Quality control is usually the responsibility of a specific
team that tests the product for defects.
