Regulations
Business Context
New business is necessary to replace attrition, enter attractive segments, and expand the portfolio. However, new policies often contain greater uncertainty than established renewals because the insurer has less direct experience with the customer and exposure. Aggressive new-business targets can therefore increase premium while gradually changing the portfolio toward risks with weaker expected performance.
Insurance TRIZ Resolution
New business should be managed through cohort-based portfolio feedback rather than aggregate premium targets alone. Insurers can track new policies by acquisition period, channel, segment, underwriting pathway, and risk characteristics, then compare their emerging performance with expectations. Capacity can be expanded rapidly where cohorts perform well and restricted where deterioration appears.
Applicable TRIZ Principles
Principle 1 – Segmentation separates new-business cohorts so their quality can be evaluated independently.
Principle 23 – Feedback uses early performance to modify acquisition and underwriting decisions.
Principle 10 – Prior Action establishes portfolio thresholds before growth occurs.
Expected Outcome
Higher-quality new business
Earlier detection of portfolio deterioration
More sustainable growth
Improved allocation of underwriting capacity
Decision Indicators
Early indicators that this contradiction is limiting portfolio performance include:
New-business loss ratios consistently exceed renewal results.
Growth targets are measured without risk-quality indicators.
Rapidly growing channels produce weak retention or claims experience.
Portfolio composition changes faster than management reporting detects.
Underwriting standards are progressively weakened for new customers.
Monitoring these indicators helps insurers prevent growth from concealing deterioration in portfolio quality.
