Measure: $30 MM of overdue receivables. Gage RR 5%. Average bill sent out 27 days after hardware. 16% of bills disputed. Analyze Used, process mapping, ANOVA and Homogeneity of Variance to pare shops: Found significant difference in both the mean and variation of overdue receivables between shops. No correlation between size/plexity of shop and $ overdue. 80% correlation between overdues vs. disputed bills and/or bills sent 30 days after hardware. Design/Improve ―Digital‖ ining inspection process established to prevent disputes. Worked with customers to allow us to bill them for estimated repairs for long cycle items. Digitally linked subtier supplier billing system into GE system, eliminating nonvalue added manual steps and lost paperwork. Validate/Control Digital inspection results provided realtime to customers for every overhaul. Accuracy of estimated billing pared to actual charges and estimation model continually refined. Currently +20%, targeting +10%. Results: 3% of bills disputed. Average bill sent out 5 days after hardware. Overdue receivables reduced by $29 MM.
