B1: The Batch Size Queueing Principle
Reducing batch size reduces cycle time
B2: The Batch Size Variability Principle
Reducing batch size reduces variability in flow
B3: The Batch Size Feedback Principle
Reducing batch sizes accelerates feedback
B4: The Batch Size Risk Principle
Reducing batch size reduces risk
B5: The Batch Size Overhead Principle
Reducing batch size reduces overhead
B6: The Batch Size Efficiency Principle
Large batches reduce efficiency
B7: The Psychology Principle of Batch Size
Large batches inherently lower motivation and urgency
B8: The Batch Size Slippage Principle
Large batches cause exponential cost and schedule growth
B9: The Batch Size Death Spiral Principle
Large batches lead to even larger batches
B10: The Least Common Denominator Principle of Batch Size
The entire batch is limited by its worst element

Economic batch size is a U-curve optimization
B12: The Principle of Low Transaction Cost
Reducing transaction cost per batch lowers overall costs
B13: The Principle of Batch Size Diseconomies
Batch size reduction saves much more than you think
B14: The Batch Size Packing Principle
Small batches allow finer tuning of capacity utilization
