After 15 years in warehouse logistics, I've seen supply chains evolve from simple truck-and-shelf operations to complex global networks. But I'm wondering if the industry's obsession with just-in-time inventory has made us too fragile — a single port closure or chip shortage disrupts everything. Would we be better off accepting higher warehousing costs for more buffer stock, or is that just inefficient overreaction to rare events? I lean toward saying JIT still wins on cost, but my own experience during the pandemic makes me doubt that answer.
