Quality assurance is a planned, proactive process focused on preventing defects during development through activities like process improvement. Quality control is a reactive process focused on identifying defects after development through testing and inspection. Quality assurance aims to improve processes, while quality control aims to check for defects in the final product before release. Responsibilities also differ, with quality assurance being a shared team responsibility and quality control handled by a dedicated testing team.

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.
