causes increased costs due to rework,test and inspectionUnderstanding and controlling the causative factors(x)is the real key to high quality at low cost.The National Graduate School of Quality Management v7 14INSPECTION EXERCISEThe necessity of training farm hands for first class farms in the fatherly handling of farm livestock is foremost in the minds of farm owners.Since the forefathers of the farm owners trained the farm hands for first class farms in the fatherly handling of farm livestock,the farm owners feel they should carry on with the family tradition of training farm hands of first class farms in the fatherly handling of farm livestock because they believe it is the basis of good fundamental farm management.How many fs can you identify in 1 minute of inspection.The

17IMPROVEMENT ROADMAPBreakthroughStrategyCharacterizationPhase 1:MeasurementPhase 2:AnalysisOptimizationPhase 3:ImprovementPhase 4:ControlDefine the problem and verify the primary and secondary measurement systems.Identify the few factors which are directly influencing the problem.Determine values for the few contributing factors which resolve the problem.Determine long term control measures which will ensure that the contributing factors remain controlled.ObjectiveThe National Graduate School of Quality Management v7 18Measurements are critical.If we cant accurately measure something,we really dont know much about it.If we dont know much about it,we cant control it.If we cant control it,we are at the mercy of chance.The National Graduate School of Quality Management v7 19WHY

STATISTICSThe National Graduate School of Quality Management v7 20WHY STATISTICS?THE ROLE OF STATISTICS IN SIX SIGMA.Ignorance is not bliss,it is the food of failure and the breeding ground for loss.DR.Mikel J.HarryYears ago a statistician might have claimed that statistics dealt with the processing of data.Todays statistician will be more likely to say that statistics is concerned with decision making in the decision making in the face of uncertaintyface of uncertainty.BartlettThe National Graduate School of Quality Management v7 21mSales ReceiptsmOn Time DeliverymProcess
