Thread: Qc-Qa Difference

What is the difference between QA and QC?

Thanks ~G

Hi,
Quality Assurance is the activities that evaluates the production processes while Quality Control is the activities that identifies defects in the products. Best example of QC is Testing.
Hope this will help you.

Quality Control is a process directed at validating that a specific deliverable meets standards, is error free, and is the best deliverable that can be produced. It is a responsibility internal to the team.

QA, on the other hand, is a review with a goal of improving the process as well as the deliverable. QA is often an external process. QA is an effective approach to producing a high quality product.

Hi,

Following terminologies will exactly define you the definition of QA and QC through which you can easily differentiate:

Quality Assurance is the set of support activities which includes facilitation, training, measurement, analysis etc., needed to provide adequate confidence that process are established and continuously improved to provide products that meet spefications and are fit for use.

Quality assurance is a planned and systematic set of activities necessary to provide adequate confidence that products and services will conform to specified requirements and meet user needs.

Quality Control is hte process by which product quality is compared with applicable standards, and the action taken when nonconformance is detected. The main focus here is defect detection and removal. This is line function where the performance of the tasks is the responsibiloity of the people working within the process.

Software testing is one of the method through which the Quality control is done.
