Which statement is true about batch size?

This statement is true about batch size. Batch size is the amount of work that moves as a unit through a process or system. Large batch sizes increase variability by creating more uncertainty, complexity, dependencies, and unpredictability in the workflow. Large batch sizes also increase waste by causing delays, queues, handoffs, rework, overproduction, and inventory accumulation. Reducing batch size is one of the key ways to optimize value delivery and improve flow efficiency. References: SAFe Lean-Agile Principles, SAFe Principle #5
