This means we get to influence that quality every week rather than having to deal with historical quality issues. fast, and although a large batch size will give a more precise estimate of the gradients, in practice this does not matter much since the optimization landscape is If we started by completing all of the analysis before handing off to another team or team member to begin developing the application we would have a larger batch size than if we completed the analysis on one feature before handing it off to be developed. 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.
