Daniel Goleman cautions against solely relying on analytics to assess people and management performance. He argues that important "soft" aspects of leadership like integrity, compassion, and impact on employee morale are difficult to capture with analytics alone. The best predictor of future performance is often past performance, best evaluated by those who know the individual well. While data can provide insights, organizations also need the right culture, leadership, and storytelling to ensure analytics do not make flawed assumptions and result in false indications of performance.
