Stories may be the constituent parts of larger features, themes or epics. 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). Accomplishing flow requires eliminating the traditional start-stop-start project initiation and development process, along with the incumbent phase gates that hinder flow (seePrinciple #5and Lean Budgets).

Small batches of work are highly predictable as to when they get to production. Often, simply visualizing the current volume of work is the wake-up call that causes practitioners to start addressing the systemic problems of too much work and too little flow. You can choose to explicitly process a batch at any time, overriding both the connection batch value and the statement batch value. Related questions Hello everyone, I am currently facing a problem regarding a small GPU memory during my deep learning project. (Choose two.) Littles Lawthe seminal law of queuing theorytells us that the average wait time for service from a system equals the ratio of the average queue length divided by the average processing rate.
