TOTAL QUALITY MANAGEMENT • Marketing • Engineering • Purchasing and Production • Mechanical inspection and Functional testing • Transport,placement and service
Quality Control Cycle; • Working at the same workplace or similar jobs that employers are to analyze, solve problems, and collected at regular intervals they create small working groups. Not enough organization to apply the features of quality circles, enterprise administrators will need to carry some qualities.

Cost of prevention of defects Cost of warranty claims Costs of quality Cost of detecting defects in the final product Cost of scrap and rework of defective products
QUALİTY CİRCLE The QC circle was formally organized in Japan in 1962 by Japanese Union of Scientists and Engineers(JUSE) and the man who initiated the idea is Dr.Kaoru Ishikawa
Quality of inputs monitored Quality of outputs monitored Random disturbances Transformation process İnputs Outouts Statistical process control Feedback mechanisms
Process of QC For specific point in time • Identification of problem • Problem selection • Problem analysis • Recommendation to the Top management
