As illustrated in Figure 1, visualizing the work helps immensely. Make sure that the connection to SQL Server is successful. The batch size can be one of three options: batch mode: where the batch size is equal to the total dataset thus making the iteration and epoch values equivalent; mini-batch mode: where the batch size is greater than one but less than the total dataset size. Reducing batch size is a secret weapon in Agile software development. The economically optimal batch size depends on both the holding cost (the cost for delayed feedback, inventory decay, and delayed value delivery) and the transaction cost (the cost of preparing and implementing the batch). There is no batch value. The reason for the faster speed is obvious. If you arent, I encourage you to go through the exercises in theKanban Roadmapwith your team. Small batches guarantee lower variability flow, speed up feedback that is economically significant, and reduce the danger of delays and cost overruns. <> The needs of the market change so quickly that if we take years to develop and deliver solutions to market we risk delivering a solution to a market that has moved on.
