Workday HCM

I wanted to share our implementation of an automated workforce demand forecasting system that integrates Workday HCM with our financial planning platform. This has transformed our quarterly planning process from a 3-week manual exercise to a 2-day automated workflow with significantly better forecast accuracy metrics.

We built this using Workday’s REST API integration to extract historical headcount data, combined with machine learning model training on three years of hiring patterns, revenue growth, and seasonal fluctuations. The system now predicts hiring needs by department, role, and quarter with 87% accuracy (up from 62% with our previous manual methods).

The automated notification system alerts department heads 90 days before predicted staffing gaps, giving us time to recruit proactively rather than reactively. We’ve reduced time-to-fill by 23% and eliminated last-minute contractor spend that was costing us 40% premium rates.
