Definition

Need Consistency: Stability and coherence between stated needs and observed choices/outcomes over time.

Why it matters

Need consistency is an outcome metric for improvement (T3): higher consistency indicates your process is better aligned with your stable needs.

How to measure (practical)

  • Compare your written needs (M1 artifacts) to the eventual chosen option.
  • Track regret and post-purchase switching.
  • Track stability of weights and must-haves across repeated decisions.
