Professional engineering expert witnesses may opine on ISO 9000. Here is a summary of ISO9000 from the ISO9000 Council.
Section 5: Measurement, Analysis and Improvement
The last section of the ISO 9001:2008 standard closes the loop by providing requirements for measurement and monitoring activities, so that the company can immediately identify when not on track. Measurement and monitoring activities also include internal audits and the monitoring of customer perception as to whether the company has fulfilled customer requirements. All of these activities must be defined, planned and implemented. Measuring and monitoring allows the company to manage by fact, not by guess.► Tip: This is a very important section of the ISO 9001 standard. Depending on how it is implemented, it can add tremendous value or create bureaucracy and waste. We highly recommend placing emphasis on this crucial ISO 9001 section.
