Final answer:
JIT is a critical part of Lean Manufacturing, a comprehensive approach that aims to reduce waste and increase efficiency in production processes.
Step-by-step explanation:
JIT, or just-in-time, is indeed a critical part of a more comprehensive approach referred to as Lean Manufacturing. Lean Manufacturing focuses on reducing waste and increasing efficiency in production processes. JIT involves producing and delivering goods and materials just in time, thereby minimizing inventory costs and waste. It also promotes a smooth flow of materials and eliminates unnecessary storage and handling. For example, companies like Honda adopt JIT by having parts delivered daily to assembly plants, eliminating the need for warehouses and improving quality control.
