Title Formula for Good Quality Control
Organisation SSL International
SSL International manufactures and distributes health care products to over 130 countries. Ruth is a team leader on a line packaging a powder for foot care. The process has a number of stages all of which have to be checked for quality. She samples a finished product every half-hour for defects. If any are found they will only have to check the items produced since the previous half-hourly check.  This helps to ensure good quality control. The process involves sampling, and scaling (if one sample is satisfactory, then the previous half-hourly batch is assumed to be).
