If the scheme organizers suspect collusion then the laboratories concerned will be contacted. Each subsample is then analyzed and the results compared.

There should be no bacteria growth on the filter after incubation. The table below shows the applicability of common quality control measures to the water quality indicators covered in this manual. They are used to test the precision of the laboratory measurements. This exposes many unanticipated weaknesses in a product, and the data is used to drive engineering and manufacturing process improvements.

General Douglas MacArthur oversaw the re-building of Japan. Quality assessment incorrect PT results are not handled with sensitivity, staff may become defensive and will make more effort with PT samples in future to avoid further criticism. These practices must be discouraged by laboratory management.

These samples are analyzed and the results reported to the quality control lab. The most popular score is the Z-score, also called standard deviation index SDI.

Determine which quality checks you have the resources and capabilities to carry out. These samples are analyzed and the results compared with the known concentrations. QA is not limited to manufacturing, and can be applied to any business or non-business activity, including: Shewhart developed the control chart in and the concept of a state of statistical control.
