The Harvard study found that Boston Consulting Group consultants using generative artificial intelligence experienced a 40% improvement in task completion rates, speed, and quality. This research marks the first systematic study of the practical application of generative AI in enterprises. Some consultants adopted "Cyborg" and "Centaur" methods. The study also emphasized the ability of AI to balance skills. Although the internal workings of AI remain opaque, the research provides significant insights for businesses on how to better utilize AI.
