The document discusses whether the human resources (HR) department is considered a cost center or profit center. It notes that traditionally HR has been viewed as a cost center as it does not directly generate revenue. However, HR can help reduce costs through initiatives like self-service technology and help increase revenue by improving employee performance and retention. Empirical evidence also shows that companies with strong HR practices have higher profits and returns. By quantifying its impact, HR can demonstrate its value and transition from a cost center to a profit center.
