This multi-billion-dollar automaker, with U.S. assembly facilities and a presence on nearly every continent, deliberately sourced its Tier-1 suppliers close to the assembly plants to cut transport cost, guarantee on-time availability, allow rapid response, and keep production flexible. That design only works if every supplier feeds the line on time and on spec. The automaker ranked suppliers by risk and backed its standards with high financial penalties for missed delivery or quality, plus the expedited freight costs that failures triggered. Three suppliers were sliding toward the edge of that ranking.

The problems were structural, not occasional. The interior headliner supplier had no internal forecasting model and made poor use of its sourcing system, so warehousing ran chaotic, lines waited on parts, and expediting cost thousands per week, including the occasional chartered private transport from overseas. Finished-goods sequencing fought itself, with parts that had to be packed and loaded in reverse order for assembly-line first-use while color, capacity, size, and style options dictated a conflicting production sequence. The roofing and trim supplier could not meet quality, production, and delivery specifications and sat in penalty status. The carpet supplier, asked to ramp for a new-model rollout, had OEE too low for the added volume, oversized blanks wearing its equipment, and foamer cycle times too slow to hit target.

Across all three, high turnover in purchasing, planning, and scheduling kept erasing tribal knowledge, so even hard-won fixes did not stick. Leadership at each supplier needed more than a one-time correction. They needed operating systems and disciplines that would hold flow, quality, and delivery steady under the relentless pace of a just-in-time customer.

At the headliner supplier, POWERS rebuilt the parts-to-line flow end to end. The team set up EDI interfaces and customer order data management, converted orders into production schedules and component demand to vendors, and managed incoming components. Warehousing was optimized across an off-site satellite warehouse and the main facility, with replenishment from satellite to production, delivery to each workstation without stoppages, and managed WIP, finished-goods flow, sequencing, scrap, and launch changes. A production sideline Kanban replenishment system was installed, the in-house warehouse was physically relaid out for first-in first-out movement with reverse-order loading, minimum reorder-quantity purchasing and daily by-shift cycle counts for critical parts were established, critical parts were resourced away from poor performers, and mold-line scheduling was rebalanced to cut unnecessary changeovers.

At the roofing and trim supplier, POWERS developed a Management Operating System with front-line supervisors and managers, worked with planning and scheduling to enforce compliance to the just-in-time schedule, and developed short-interval quality metrics and systems. Eliminating the breach of sweat time let the supplier move out of Level 2 penalty status. At the carpet supplier, the team built a Management Operating System with front-line leaders, created set-up checklists to kill startup lost time, staged product to cut wait on the next pallet, installed Quality Vision Systems, tracked hourly production by work cell, and brought in tooling and ACL-line OEM support to lift uptime and reduce scrap. New second and third shifts were recruited and trained for a 24-hour continuous run.

Run in parallel across the three suppliers, the work moved each one from reacting to controlling. The headliner supplier’s flow stopped fighting itself, the roofing and trim supplier had a system its leaders could run every shift, and the carpet supplier had the OEE, tooling, and staffing to carry the launch volume.
