Failure Mode and Effects Analysis (FMEA) is a method used to identify and address risks in any process. It involves evaluating the process and listing any potential causes of failure. A score is then assigned to each. These are ranked in three separate areas – severity, opportunity and detection.


Statistical process control utilizes tools such as control charts to uncover special causes in a process. This is variation that is not inherent and makes the process go out of control. Once this is addressed then there can be a greater focus on stabilizing and improving.


All measurement and inspection tools have some degree of error present within them. Measurement systems analysis aims to quantify this variation and ensure that it is capable of delivering results that are up to expectations. One of the main principles is gage repeatability and reproducibility (GR&R), which is a structured experiment to define precision and accuracy.


Advanced product quality planning is a structured approach to designing and introducing products into production. It also brings customer requirements further into the forefront. It is cross functional and typically stretches over several phases of the design process.
