Predicting flight risk. Prescribing retention.

A machine-learning model that finds front-line associates at risk of leaving, then hands their manager a specific, ready-to-use retention action inside the tools they already use.

Bias-monitored and auditable by design. Protected attributes are excluded and parity is checked every run, so every score is explainable and defensible.

The challenge

A revolving door at the front door

Front-line customer care is the front door of a health plan. It is also one of the hardest jobs to keep staffed: first-year attrition ran as high as 90% in some markets, driving an estimated $200M a year in recruiting, training, and upskilling, and putting member service and experience at risk.

Leadership wanted to stabilize the talent base and reduce reliance on reductions in force. The ask was not another report. It was a way to see risk early enough to act, and to act at the level of the individual associate and their manager.

The approach

Predict early, prescribe clearly, deliver in-flow

Predict, don’t react

An XGBoost model trained on 18-to-6-month history scores flight risk for recent hires with at least one survey response, before they quietly disengage.

Auditable by design

Protected attributes are excluded and parity is monitored, so HR and Legal can trust and defend every score. Nothing is a black box.

Prescribe the next step

Embedded GenAI turns each score into a specific, manager-ready retention action. Not just a number, but a move.

Enable the manager

Training, playbooks, and coaching helped managers act on the insight, delivered inside Workday and Tableau with automated notifications.

The COO’s organization recognized the work for its speed and effectiveness: a working pilot delivered in weeks, not quarters.

Risk score + trendGenAI recommended actionAct before it is too late

Each manager sees risk scores, trends, and a GenAI-recommended action for their own team, inside the tools they already use.

6Enablement & change management
Manager trainingAction playbooksCoachingReinforced at scale

Managers did not act alone. Targeted training, action playbooks, and hands-on coaching helped them use the insights well and hold the retention conversations that matter. This enablement ran through the pilot and was built into the scaled rollout, so adoption held as the program grew.

The dashboard

What leaders and managers saw

Executives triaged risk by market; managers received a ranked action list for their own team. The view below is an interactive reconstruction. Explore it.

Inside a score

How a risk score is built

Every score is explainable. Pick an associate to see the signals driving their risk, and the action the model recommends.

The result

Attrition bent down in ten weeks

In the pilot markets, monthly attrition fell about 25%, from 19.5% to 14.7% (a 4.8-point drop), against a matched control, saving an estimated $1.8M during the pilot and a projected $9.6M in year one. Manager enablement and change-management support were a deliberate part of the design, and were carried into the scaled rollout to keep adoption strong.
