The Five Levels of Warehouse Complexity

Each company in this dataset was scored against the Warehouse Complexity Index, derived from Gartner’s enterprise warehouse complexity framework. Table 2 shows the distribution by complexity level. This sample largely contains companies operating at levels L1 through L4, with nearly half operating at Level 2.The Five Levels of Warehouse Complexity-1
