Discussion Themes
• Predictive Modeling provides the toolset to assist with a variety of critical business operations
• The market is softening and better risk assessment capabilities are needed to avoid inappropriate soft market dynamics and naïve reactions
• Predictive Models can be implemented in ways that do not require complex, expensive efforts
• The financial benefits that can be realized from predictive models are very significant – phased and rapid implementation can help fund additional future analytics and more complex implementations
• The three most important parts of any predictive modeling project are (1) implementation; (2) implementation; and (3) implementation – building a great model should be a given

A Predictive Modeling Approach
Building and deploying predictive models requires a specialized combination of skills covering data management, data cleansing, data mart construction, actuarial and statistical analysis, data mining and modeling, and insurance operational and business processing and technologies

What The Process IS NOT – What it IS
What it IS NOT
• A Black Box approach
• Stock delivery
• Replacement for underwriters
• Score used to communicate decision
• Score drives results
• A single variable magic bullet
• Actuarial and/or systems project
• Class plan underwriting
What it IS
• Scoring drivers are known / understood
• Collaborative throughout the business
• Additional underwriting toolset
• Reason codes / messages are developed
• Implementation drives results
• Relationship among variables is power
• Business initiative
• Efficient segmentation of policyholders

Perform Metrics & Reporting
• Predictive Models must be effectively implemented to derive their benefit potential
• The financial benefits can be so significant that urgency should drive the pace of the project
• Create a benefit analysis and use the benefits to drive the project – a complex process (PIF
counts, LR management, retention, not written, etc)
• Competitive jockeying should also drive project pace – first adopter advantages
• A best practice is to create a continuum of implementation solutions and phases
• Initial implementation should focus on extracting value from models before automation
• Tactical implementation can be achieved in 2-4 months
• Planning, planning, and then some more planning

Perform Metrics & Reporting
• Steering Committee and Project Committee Structure
• Phased structure and focus on 80:20 Rule
• Development of End-State-Vision & Project Planning Document – some key questions are:
• How will predictive modeling guide decision making, pricing, and tier placement?
• How will predictive models impact existing business processes (e.g. by line / account)?
• How will predictive models be blended into the field and agency management process?
• What key performance measures must be achieved?
• How will underwriters/raters/other personnel’s compliance be measured?
• What level of automation is desired for various business processes?
