What is the Quality Assurance?
Quality Assurance or QA in short contains all those planned and systematic actions necessary to supply adequate confidence that a product or service will satisfy/fulfill given requirements for Quality.
QA includes Quality Control (QC), but it emphasizes quality in the design of products and processes.
What is Quality Control?
Quality Control or QC, in short, is the process through which we measure the actual quality performance and compare it with the set standards and whether, if there is a deviation then we take corrective actions.
The typically quality control program is based on periodic inspection, followed by feedback of the results and change or adjustments whenever required.
