JaeGeun Byun, Auto Pricing Manager at Hana Insurance, shares how Radar replaced manual processes with real-time, data-driven pricing, delivering speed and regulatory compliance in Korea's fast-moving market.
The Korean auto insurance market operates at an intense pace. Rates shift weekly, consumer expectations evolve constantly, and competitive pressures demand both precision and agility. For insurers operating in this environment, the ability to make accurate, defensible pricing decisions quickly isn't just an advantage, it's essential for survival.
Hana Insurance faced the dual challenge of staying competitive while meeting stringent regulatory requirements. Their traditional pricing infrastructure, built on manual processes and legacy systems, couldn't bridge this gap. Through their partnership with WTW and the implementation of Radar, the company transformed how pricing decisions are made.
The challenge
Before implementing Radar, Hana Insurance's pricing team operated with limited visibility into the potential impact of their decisions. Hours were spent writing complex SQL queries just to explore basic scenarios. In a market where rates change weekly, this manual approach created strategic limitations. Dynamic pricing remained out of reach, and the team found themselves constantly reacting to market changes rather than anticipating them.
The solution
Radar fundamentally redefined the entire workflow from coding-intensive manual processes to strategic, insight-driven decision-making. Speed became the most visible difference. Tasks that once consumed hours of development time now complete instantly, with the team able to adjust rates for specific customer segments and immediately see the projected impact across their entire book of business. What used to take a full day of SQL coding now happens in five seconds.
In a market where conditions change weekly, this capability opens new strategic possibilities. The ability to test multiple scenarios, evaluate outcomes, and implement changes quickly provides substantial competitive advantage. The company has moved from following market trends to actively shaping them, capturing opportunities as they emerge.
Evidence-based decision making
The transformation extends beyond operational efficiency to fundamentally change how pricing decisions are made. Where pricing once relied on intuition and experience, decisions now rest on statistical validation and rigorous analysis. Radar has transformed data from a historical record into an active decision-making asset.
This evidence-based approach enables proactive management. Rather than waiting for market shifts to occur and then reacting, the team now simulates future scenarios and develops contingency plans in advance. They can model the impact of potential market moves, test strategic options, and enter uncertain situations with clarity about likely outcomes.
Balancing innovation and regulation
One of Hana Insurance's most significant achievements has been reconciling innovation with regulation, two objectives that often seem fundamentally opposed in the insurance industry. The company leverages sophisticated machine learning models to identify complex risk patterns and pricing signals that traditional methods miss. However, Radar maintains transparency throughout the modeling

process, ensuring that even the most complex analytical insights can be translated into terms regulators understand and accept.

By building analytical sophistication on a foundation of explainability, Hana Insurance has created a sustainable competitive advantage. As they develop deeper capabilities, their regulatory position strengthens rather than becoming more precarious.
Results
The implementation has delivered measurable impact across multiple dimensions:
Speed and agility
The company has transformed from an organization that struggled to keep pace with market changes into one that leads them. The ability to analyze, test, and implement pricing adjustments in seconds rather than days creates opportunities that slower competitors cannot capture.
Democratized analytics
Capabilities that once required specialized technical expertise are now accessible to the broader pricing team, enabling more people to contribute strategic insights. This shift accelerates innovation and embeds data-driven thinking throughout the company.
Competitive positioning
As Hana Insurance continues building analytical capabilities and refining their models, they strengthen their competitive position. Each improvement compounds the advantage, widening the gap between their capabilities and those of their competitors.
Looking ahead
Hana Insurance's transformation illustrates a broader evolution underway across the insurance industry. Success in modern markets requires more than strong data or sophisticated models. It demands the ability to convert insights into action faster than competitors while maintaining regulatory integrity.
Through their partnership with WTW, Hana Insurance has built a foundation that positions them to actively shape market dynamics rather than simply respond to them. As they continue refining their capabilities and exploring new possibilities in pricing innovation, the benefits extend beyond the company to the broader industry. The future of insurance pricing is characterized by speed, precision, and intelligence. Hana Insurance is demonstrating what that future looks like.
