This document compares the supply chains of three different types of companies - a slow company, a faster company, and a modern company with optimized supply chain skills. The slow company has multiple unoptimized warehouses, high inventory levels, and high logistics costs. The faster company has more resources but also higher inventory levels. The modern company has optimized settings with quick delivery times, lower inventory levels, and handles full truckloads efficiently using smaller, specialized warehouses and a centralized logistics hub.
