Which statement is true about batch size?

According to the principles of product development flow, large batch sizes are a primary cause of delays and inefficiencies. They increase the variability and risk in the development process, making outcomes less predictable. Large batches lead to longer cycle times, delayed feedback, and a higher likelihood of extensive rework. Conversely, small batches enable faster flow, quicker feedback, and lower variability, which are core tenets of Lean-Agile development and SAFe Principle #6.

A. Handoff batches should be made as small as possible to reduce delays and improve the flow of value.
B. Large batch sizes delay feedback, which is antithetical to Built-In Quality practices that rely on fast feedback loops.
D. Breaking Stories into tasks is a planning technique; it does not inherently define the batch size of value flowing through the system.
