Turning roofing orders into the right steel purchases, months ahead
A mid-size manufacturer of metal roofing and siding makes panels and trim at several Midwest plants and sells to lumber yards. Its raw material, steel coil, takes months to arrive. Convexity turns demand for finished products into coil requirements, plant by plant, so purchasing starts from what will be built.
Before Convexity
Demand comes in as finished panels and trim, in a mix of colors and gauges that keeps changing. Turning that back into how much coil each plant needs lived in people’s heads and spreadsheets.
Planning used last year plus a growth factor, the business is strongly seasonal, and there was no sales and operations planning process. When demand jumped, the plants felt it first.
What Convexity does
Bills of material and yield rules turn panel and trim demand into coil requirements for each plant. Demand from every plant rolls up into one view with the coil supplier, and forecasts by item and plant drive stock policies within a cash budget.
Planners approve every purchase and transfer, and can test what-if scenarios before they commit.
Results and what’s next
Fewer plant stockouts in peak season because coil needs are visible a season ahead, less excess in slow colors and gauges, and planners who review recommendations instead of rebuilding the math each month.
