Quality systems error handling

This incident caused an error in an operation sheet of procedure G 8 (Operation to Handling changeover) on a newer version published in 1991. It was not detected by the quality assurance system used to draft the... 

The ability to accurately foUow the radial and axial motions of the spinning disk results directly from the quality of the focus and tracking actuators. To reject the errors due to shock, vibration, and media runout, the servosystem must have high bandwidth. The limitation to achieving high bandwidth is usually the resonance modes of the actuator. As the actuators are reduced in size, the frequencies of the resonances become higher and the achievable bandwidth of the system rises. Servosystems in optical drives face additional challenges because they have to handle removable media, which has variations between different disks (such as media tilt). 

This chapter discusses aspects of quality assurance of equipment as used in analytical laboratories. It provides guidelines on how to select a vendor and for installation and operational qualifications, ongoing performance control, maintenance, and error detection and handling that contribute to assuring the quality of analytical laboratory data. It refers mainly to an automated chromatography system as an example, but similar principles can be applied to other instrumentation. 

As the benefits provided by the U.S. Food Stamp Program are entirely federally funded but eligibility determination is handled at the local level, the federal government mandates a thorough system of quality control that it has developed to monitor and reduce errors in eligibility.
