The reason for the faster speed is obvious. Many of the practical tools for reducing batch size achieve this by increasing transparency, making communication easier, precluding the need for handoff, and automating and hardening processes. Small batch production is a process during the manufacturing phase where your product is created in specific groups and smaller quantities than traditional batch processing.Small batches go through the system more quickly and with less variability, which fosters faster learning.The reason for the faster speed is obvious.The reduced variability results from the smaller number of items in the batch.
