Final answer:
The activity not part of Just-In-Time production is 'produce in long production runs to reduce the impact of setup costs.' JIT focuses on efficiency by reducing waste and inventory costs through producing in small lots and a pull system based on demand.
Step-by-step explanation:
The activity that is NOT part of Just-In-Time (JIT) production is 'produce in long production runs to reduce the impact of setup costs.' JIT is an inventory management system and a production strategy that aims to decrease waste by receiving goods only as they are needed in the production process, thus reducing inventory costs. This method contrasts with long production runs used to amortize setup costs over a larger number of units, which goes against the JIT philosophy of producing in small lots and reducing inventory levels.
JIT involves having a pull system to move inventory, which means production schedules are driven by demand rather than forecasting. It also necessitates close communication with suppliers and a focus on continuous improvement, including efforts to reduce setup time for production. Thus, producing in long production runs, which typically leads to higher inventory levels, does not align with JIT principles.
The goal of JIT is to increase efficiency and decrease waste by receiving goods only as needed during the production process, and to produce in small lots to meet demand without overproduction.
