(JIT) Just-in-time Inventory Management systems began to appear in the United States in the Late 1970’s manufacturing space. The theory was sound: Improve the efficiency and profitability of production systems by maintaining minimal levels of inventory across the board. Depending on the industry, this management system worked well between late-stage manufacturers and customers. Problems arose with this theory, however, once down-stream supply chain producers attempted to operate by the same JIT principals. Discuss why this may happen, and what the unintended consequences may be. Give specific examples if you can. Examples needed.
