higher standards than other performers which explains higher rejects during the productionprocess. We checked if high performers make more complex products and that that might bethe reason why they have higher rejects. However the regression analysis of percent of rejecton complexity of bill of material reveals that the regression model is insignificant (R=0,015,R2=0,00). Correlations between bill of material and percent of rejects are also insignificant(r=0,015).Figure 7. Complexity of bill of materialFinally we looked at operative best practices to see why best performers so much better thenthe rest are. In Figure 8. we depict all best practices and in Figure 9. we depict only thedifference in usage of best practices between high and medium performers. From thesefigures the biggest difference is in usage of Six sigma methodology. Six sigma methodologyhas very strict acceptance rates for quality (3,4 defect per million produced products) and thismight explain why the reject rates from high performers are so much larger then from the restof performers.Figure 8: The level of usage of best practices~ 14 ~
