In this article, we are explaining the difference between traditional batch processing and Single piece flow. This understanding is critical for the successful implementation of Single piece flow which is the foundation of Lean Philosophy.

Traditional Batch processing

In traditional batch processing, every operation of the products are done in batches or lots. This creates high work in progress of items between the stations, thereby creating the inventory waste.  This high WIP makes the identification of quality issues very difficult and hence creating the defects waste. Also,the traditional batch processing is a push process in which the production happens based on the production schedule and not based on the pull of the customer.
