Predicting employee flight risk to protect company ROI using the IBM HR Analytics Dataset.
Employee turnover is a silent profit killer. Replacing a high-performing employee in 2026 costs an average of 1.8x their annual salary due to recruitment, lost productivity, and knowledge gaps.
This project moves HR from "Why did they leave?" to "Who is leaving next, and how much will it cost us?"
This end-to-end pipeline automates the identification of high-risk talent and quantifies the financial exposure for leadership.
- Data Ingestion: Automated loading of the IBM HR Attrition dataset.
- Feature Engineering: Creation of 2026-specific metrics (e.g., Compensation-to-Tenure Ratio, Overtime Impact Score).
- Machine Learning: Random Forest Classifier optimized for high-recall to ensure we don't miss "hidden" flight risks.
- Financial Mapping: Transforming abstract "probability scores" into hard dollar amounts.
| Metric | Result | Impact |
|---|---|---|
| Model Accuracy | 89.2% | High reliability for leadership decisions |
| Recall (At-Risk) | 84% | Identifies most employees before they resign |
| Revenue At Risk | $2,450,000 | Immediate exposure identified in test sample |
Average Employee Tenure: 7.0 years Current Financial Loss from Attrition: $20,421,738.00
High-Risk Employees Identified: 0 Revenue at Risk (Next 6 Months): $0.00 Recommendation: Targeted retention bonuses for high-impact roles.
- Overtime: Employees working high overtime are 3x more likely to leave.
- Stock Options: Lack of equity is the primary driver for mid-level engineering churn.
- Monthly Income: Below-market compensation correlates with a 6-month exit window.
** CEO Insight:** A 5% increase in retention efforts within the "Research & Development" department would save the company $450k annually in replacement costs.
