HR analyzes key metrics like employee performance, attrition, and return on investment (ROI) from training programs. Regarding performance, most employees ranked A for high performance. Training plan L10 correlated with high performers, so modifying other plans based on L10 may improve performance. For attrition, moderate satisfiers often left voluntarily due to high course costs. ROI analysis found highest bonuses went to high performers, though low performers received more than average performers. Training costs were higher for low performers but did not improve performance much. Course costs balanced training investments when costs were reasonable.
