Business Context
Personalized pricing can improve alignment between individual premiums and expected risk by incorporating increasingly specific customer and exposure characteristics. However, extensive individualization can make portfolio behavior more difficult to interpret, particularly when many small pricing adjustments interact across large books of business. Standardized pricing improves aggregate predictability but may obscure meaningful differences among risks.
Insurance TRIZ Resolution
Individual pricing can operate within governed portfolio bands. Detailed models determine relative risk within segments, while portfolio-level constraints establish acceptable ranges for aggregate rate adequacy, concentration, and volatility. Management can therefore retain individualized differentiation while monitoring performance through stable portfolio structures.
Applicable TRIZ Principles
Principle 7 – Nested Doll places individualized prices within broader portfolio pricing boundaries.
Principle 1 – Segmentation maintains interpretable portfolio groups around granular individual decisions.
Principle 23 – Feedback compares actual segment performance with personalized pricing expectations.
Expected Outcome
Greater pricing personalization
Maintained portfolio visibility
Better rate adequacy
More predictable aggregate performance
Decision Indicators
Early indicators that this contradiction is limiting pricing performance include:
Management cannot explain aggregate movements generated by individual pricing models.
Portfolio reporting becomes disconnected from pricing segmentation.
Highly personalized rates produce unexpected business-mix changes.
Actuarial teams struggle to validate performance across extremely small segments.
Simplification is proposed primarily because personalized pricing has become difficult to govern.
Monitoring these indicators helps insurers preserve individual risk differentiation while maintaining an interpretable portfolio structure.
