Overview
Child Support Payment Predictor Scope of Study: 1,033 cases opened 10/2011 through 5/2013 No prior support order Objective: To establish a payer classification predictive tool that prognosticates the NCPs who are potentially at risk to fall behind on their child support payments. Provide staff with a tool to more effectively perform intervention on cases.
Child Support Payment Predictor Data Elements 466 data elements from the case and participants 68 field variables were created as candidates for exploratory data analysis 29 variables were selected for model building 8 variables remain in the final model
Child Support Payment Predictor Model data points NCP s Employment stability Incarceration history Unemployment in previous year Living status in previous year Default history on first order NCP s email information NCP s employment status at initial order establishment Other NCP Demographic data
Child Support Payment Predictor Payment Predictor Details Multinomial logistics regression used 4 payer groups created: Extremely rare payer (0%-30%) Rare payer (31% to 50%) Attempt payer (51 to 80%) Constant payer (81% or greater) Distribution of 6 month average payment rate (N=1033)
Child Support Payment Predictor By payment class Extremely rare payor (0%-30%) Rare payor (31% to 50%) Attempt payor (51 to 80%) Constant payor (81% or greater) Total due vs. Total payment for each payor class
Child Support Payment Predictor Time to order or waiting time Shortest - 2months Longest- 19 months
Child Support Payment Predictor Variable NCP e-mail address 54% had e-mail addresses Strong impact on payer class
Child Support Payment Predictor Results: Prediction accuracy of the model 62.5% Percentage of the caseload more accurately monitored 14% Able to target/focus on at risk cases before they become delinquent

A Smarter WAY TO PLAN
Overview What is Business Intelligence? Set of theories, methodologies, processes and technologies that transform raw data into meaningful and useful information. Why do we need Business Intelligence? Reaching limit of producing NEW reporting and analytical results. Paradigm shift from reactive reporting (the past) to proactive reporting (looking into the future). Who is likely to participate in the process? Who is likely to pay their child support? What will our caseload look like in 5 years?
Smarter Planning A new way to plan Smarter Strategic Planning Strategic Planning Tool predict future case loads, staffing needs, budget and performance. Smarter Case/Knowledge Worker Case Stratification Tool - Based on certain case data predictors, will be able to predict case outcomes with high probability. Reduce Case Loads: Focus on cases that need personal touch automate others. Change Individual Case and Family Outcomes Proactive Case Management Targeted Early Intervention Keep Families Intact
