V1: The Principle of Beneficial Variability Variability can create economic value
V2: The Principle of Asymmetric Payoffs payoff asymmetries enable variability to create economic value
V3: The Principle of Optimum Variability Variability should neither be minimized or maximized
V4: The Principle of Optimum Failure Rate Fifty percent failure rate is usually optimum for generating information
V5: The Principle of Variability Pooling Overall variation decreases when uncorrelated random tasks are combined
V6: The Principle of Short-Term Forecasting Forecasting becomes exponentially easier at short time-horizons
V7: The Principle of Small Experiments Many small experiments produce less variation than one big one
V8: The Repetition Principle Repetition reduces variation
V9: The Reuse Principle Reuse reduces variability
V10: The Principle of Negative Covariance We can reduce variance by applying a counterbalancing effect
V11: The Buffer Principle Buffers trade money for variability reduction
V12: The Principle of Variability Consequence Reducing consequences is usually the best way to reduce the cost of variability
V13: The Nonlinearity Principle Operate in the linear range of system performance
V14: The Principle of Variability Substitution Substitute cheap variability for expensive variability
V15: The Principle of Iteration Speed It is usually better to improve iteration speed than defect rate
V16: The Principle of Variability Displacement Move variability to the process stage where its cost is lowest
