The Saint-Gobain Sekurit project produced a dual outcome that traditional planning systems struggle to deliver simultaneously: product availability rose from 95.8% to 97.2% (1.4 points), while inventory levels fell by 9.25%. The 97% average availability rate across the 30 distribution centers translates directly into protected revenue: spare-parts customers who find the right glass at the local warehouse do not call a competitor. The seasonality effect was also tamed, with the availability curve becoming much more stable through the year and eliminating the deep seasonal dips that previously disrupted service to garages and fitting centers. The +15% forecast accuracy gain at SKU level cascaded into better replenishment decisions, smoother production planning at the 3 European plants, and freed inventory turnover capacity across the network. Inventory turnover improved, freeing working capital and warehouse space. For an automotive aftermarket business where insurance-driven turnaround expectations are tight and competitors are one phone call away, these gains translate directly into market share defense.
