Quality control and quality assurance are two essential concepts that help ensure the safety and quality of the finished products.
While both concepts share the same goal of maintaining high standards, they approach this goal in different ways.
Quality control involves inspecting and testing products at various stages of production to ensure that they meet the required specifications and standards.
Quality assurance, on the other hand, is a broader approach that involves the development and implementation of processes and systems to ensure that the products consistently meet the required standards.
QC vs QA
- QC focused on detecting and correcting errors.
- QA focused on preventing defects and errors.
- QC works on reactive approach that involves inspecting and testing products.
- QA works on proactive approach that involves identifying and addressing potential issues before that become problems.
- QC involves the use of statistical sampling and testing methods to evaluate the quality of products.
- QA involves the use of quality management principles and continuous improvement techniques.
- QC ensures that the product meet required specifications and standards.
- QA ensures the processes used to produce the product are optimized to minimize defects and errors.
