During a process analysis, we identified various sources of waste in production. We found the most opportunities for improvement in production planning and scheduling and related inventory management in the warehouse. In its original state, Modus operated with a lead time of approximately three weeks from order receipt to handover of the finished product to the customer. The key to rapidly reducing production operations was to increase information support, reduce the number of production stages and identify suitable semi-finished products to hold in stock. As a result, we were able to reduce the number of production blanks from the original nearly 6,000 variants to just 1,700.
