What does the term "buffer" refer to in inventory management?

1. Finished goods before delivery

2. Materials awaiting further processing

3. Excess stock at the end of the production line

4. Units that are under inspection

The correct answer is: Materials awaiting further processing

In inventory management, the term "buffer" specifically refers to materials that are awaiting further processing. Buffers are added to a production system to ensure a smooth flow of operations, allowing companies to handle variabilities in production rates, demand fluctuations, and processing times. This helps prevent disruptions that could arise from delays or unexpected issues in supply chains. By maintaining a buffer of materials, organizations can mitigate the risk of stockouts and ensure that production processes continue seamlessly. This is particularly critical in lean manufacturing environments, where the goal is to reduce waste and optimize efficiency while still meeting customer demands. The other options represent different stages or aspects of inventory but do not align with the specific concept of a "buffer." For instance, finished goods before delivery refers to the end product ready for distribution, while excess stock at the end of the production line indicates surplus inventory not necessarily linked to processing continuity. Units that are under inspection refer to items undergoing quality checks and are not actively contributing to the production flow until cleared.
