Big data analytics cannot capture all important insights about an organization. Some flaws in big data can be attributed to unreasonable managers who bully employees. As a result, many consultants left their jobs due to this toxic work environment. Additionally, big data relies on the questions asked and can make incorrect assumptions. It is difficult to identify truly meaningful metrics for measuring organizational success based on massive datasets alone. Managers should focus on both performance and employee well-being to achieve long-term success, learning from examples like Google's hiring process that respects individuals' limits. Past performance does not always predict future behavior due to unmeasured variables.
