When manufacturing a product, it is recommended or even mandatory to check if it complies with the pre-established specifications or requirements. This is the guarantee of a quality product with a consistent quality/price ratio.
Quality control also allows the detection of drifts in the manufacturing process over time. These deviations are sources of loss of time and money. Quality control is based on descriptive statistics, cause-and-effect diagrams, control charts and capability tools.
As an example, regarding quality control, the SMCS has worked on the implementation of the quality monitoring of the blood treatment process for the Belgian Red Cross Blood Service.
