QA and AC Engineering and Management Tools

Quality Control
Relates to a specific product or service.
Verifies whether specific attributes are in, or are not in, a specific product or service.
Identifies defects for the primary purpose of correction defects. Is the responsibility of team/workers.
Is concerned with a specific product.

Quality Assurance
Helps establish process.
Sets up measurements programs to evaluate processes.
Identifies weakness in processes and improves them.
Is management responsibility, frequently performed by staff function.
Is concerned with all of the products that will ever be produced by a process.
Is sometimes called quality control over Quality Control because it evaluates whether quality is working.
QA personnel should not ever perform Quality Control unless it is to validate QC.
