Many people use the terms Quality Assurance (QA) and Quality Control (QC) interchangeably, but they play different yet complementary roles in delivering customer satisfaction.
It all starts with the Voice of the Customer. Customer needs and expectations are translated by the Engineering team into product specifications, drawings, standards, and requirements.
đš Quality Assurance (QA) focuses on the process.
QA ensures that the systems, procedures, training, and standards are in place so the product can consistently meet the engineering specifications.
đš Quality Control (QC) focuses on the product.
QC verifies through inspections, measurements, and testing that the actual product conforms to those specifications before reaching the customer.
Think of it this way:
Customer Requirements âĄď¸ Engineering Specifications âĄď¸ Quality Assurance Builds the Process âĄď¸ Quality Control Verifies the Output âĄď¸ Customer Satisfaction
When QA and QC work together effectively, organizations can reduce defects, improve consistency, and build customer trust through quality products and services.
Quality is not just about inspectionâit is about creating a system that consistently delivers what the customer values.
