4.20 Statistical Techniques

In our company, we have various repetitive processes used in the manufacture of our product.


We believe it is important to use statistical techniques to measure and validate our processes and to make sure our product characteristics are as stated. This is to avoid the risk of having incorrect information on our product's quality and on the effectiveness of its work processes.

We believe that effective use of statistical techniques will result in reduced costs due to eliminating wasted effort and material. It will also ultimately result in increased business due to customer satisfaction from getting expected goods and services.


Thus, in order to verify the acceptability of our process capability and our product characteristics, it is the policy of this company to adhere to the ISO 9001 section 4.20 standard on Statistical Techniques and always use adequate statistical techniques.

It is also the policy of this company to use our Procedure 4.20 for identifying those adequate statistical techniques required for verifying the acceptability of our process capability and our product characteristics.
