Now coming to your Query,PDCA is the basic foundation of all quality assurance activities and it is embodied in all QMS standards.The QC Story approach is not an approved jargon in any standard.You can have QC story,6 SIGMA,TQM,and any other wild creation you choose but you SHALL ensure that all requirements of TS16949 are met.
