A large fleet of field service technicians supported residential and commercial clients across the USA with tens of thousands of unique SKUs. Common items were pushed to trucks based on forecasted usage, while lower-use items were ordered ad hoc through the customer ERP and picked up from branches or local distributors. Because technicians could not always predict exact needs, they often ordered more than required, and with limited space to offload at local branches, excess inventory stayed on trucks indefinitely.
Overcrowded trucks made it hard to find parts, increased repurchases of items already on hand, and led to packaging wear from vibration and friction that contributed to out-of-box failures. Defective parts discovered at installation often missed retailer return windows, eliminating credit opportunities. Some inventory even remained on trucks long enough to become obsolete after newer versions were released. The customer also estimated material fuel waste from driving with excess weight.
