I am absolutly sure most morgan employees turn up to do a good job, but being human, mistakes will be made. Morgan currently do a PDI at the end of their assebly process and statistics tell us that if you fire enough defects into a manual inspection process, defects will get through. Also this will get worse over time if not corrected. (I know that defect went through ok last week and it soon becomes the norm) If I wanted to improve the warranty claims for poor quatity, I would introduce PDI's at each major assembly point and cars would not be allowed to proceed without being 100% correct. (signed of initally by head of dept as its only 15-20 cars per week) Also employees in subsequent departments should be allowed to reject cars with faults found.
Only problem with this type of approach is that it will slow production rates until a 'right first time culture' is adopted by all personal. Hence a brave management team would be required to see it through and the reason most avoid it.
