Being the global standard for quality management systems in medical devices; ISO 13485 has many controls and checks built in at various stages of the product design and development. One of these is the ISO 13485 statistical techniques procedure. This is a means to ensuring that product characteristics and process capability are measured and checked in a statistical manner to ensure their conformity with the relevant global standards.
Processes are at the core of statistical techniques
ISO 13485 statistical techniques procedure is all about matters like processes, process approach, how processes can be improved, and how effective and efficient a process is. We can understand ISO 13485 statistical techniques procedure as statistical methodologies that can be used as the basis for a whole lot of quality procedures such as sampling plan(s), quality assurance, failure analysis, and general data analysis.
All procedures are important and have to be statistical
The important point ISO 13485 statistical techniques procedure is that this has to be incorporated into the entire chain of quality procedures, as we just saw. For example, in situations where sampling is to be carried out for the purpose of establishing product characteristics and process capability, the sampling has to be based on established statistical methodologies.
The same goes for other procedures such as quality assurance, failure analysis, and general data analysis. In carrying out each of these; the quality personnel have to base their work on established statistical methodologies.
