Zero defect

Quality in Japan. Japanese economic prowess has been attributed variously to such quahty improvement activities as quahty circles, statistical process control (SPG), just-in-time dehvery (JIT), and zero defects (ZD). However, the real key to success hes in the apphcation of numerous quahty improvement tools as part of a management philosophy called Kaizen, which means continuous improvement (10). 

Zero Defects. Whereas 2ero defects was often iaterpreted to be a quahty goal, its full meaning is to encourage continuous quahty improvement (17). When ZD was treated only as a slogan, it failed to have a lasting impact.

The standard requires the acceptance criteria for attibute data sampling plans to be zero defects. 

Don t apply AQLs to attribute data - set the standard as zero defects. 

Quality system regulation The past good manufacturing practice (GMP) and process validation (PV) was renamed to quality system regulation (QSR). It is important for the medical device industry (that uses an extensive amount of plastics) and also in other product industries where they want to follow strict processing procedures. It sets up an important procedure for many plastic fabricators to consider that targets to ensure meeting zero defects.

Perhaps this is the way it should be - in essence, a zero defect policy for all research proposals. On the other hand, perhaps the process has become so laborious and frustrating that researchers postpone or abandon useful experiments. Ethics is not a simple subject. Today it is a new profession. Practitioners, called ethicists , have increasing power to judge whether certain kinds of experiments are permissible. Their opinions, although not always binding, strongly influence both investigators and review committees. 

Philip B. Crosby was an internationally known quality expert. He is best known for popularizing the Zero Defects concept and the four absolutes for quality management that originated in the United States at the Martin Marietta Corporation where Crosby worked during the 1960s.

Acceptable quality characteristics, or specifications, are generally described in terms of discrete or attribute data (e.g., pass/fail or no unit outside 75% to 125%) and are inappropriately referred to as zero defect or tolerance (since these are for the sample tested). 

It is clear that the aim of pharmaceutical research is to achieve zero defects and zero batch rejections, and this can be verified by process validation. One must bear in mind that exhaustive finished testing of product is not a substitute for in-process controls and process validation. 

Typical applications are relay switches, connectors, terminal strips, electronic parts, and many other military applications where zero defect programs and electrical reliability are of utmost importance.

Much has been learned in the thirty-five years since the demonstration of the first GaAs injection lasers [1,2], The main lesson from that period is that defect-free material is needed, hi the 1970s MITI set up a successful five year crash programme to make zero-defect GaAs. The reason behind the zero defect goal for diode lasers is that defects cause emission line broadening, and the threshold current for an injection laser is directly proportional to the emission linewidth. Excitons in semiconductors are very fragile. They can be easily destroyed, or have their linewidth broadened by crystal lattice disruptions of any sort.
