True or False: One-piece flow minimizes inventory in and between processes, reducing waste and lead-time.

One-piece flow refers to a manufacturing process where items are moved through the production system one at a time, rather than in batches. This method is effective in minimizing inventory levels in and between processes, as it reduces the amount of work in progress (WIP) that can accumulate at different stages of production. By focusing on a single item at a time, one-piece flow also helps to streamline operations, leading to reduced lead times.

When inventory is kept low, it not only decreases carrying costs but also highlights inefficiencies and bottlenecks within the process, as there is less buffer stock to mask issues. This visibility encourages timely problem-solving and continuous improvement, aligning with the Six Sigma goals of reducing waste and optimizing processes.

In the context of this statement, the assertion that one-piece flow minimizes inventory and reduces waste and lead time holds true. This approach is beneficial across various manufacturing and production environments, highlighting its effectiveness in promoting efficiency.
