Harvard Business School: The Cybernetic Teammate – A Field Experiment on Generative AI Reshaping Teamwork and Expertise

Summary of Read Full Report

This working paper details a field experiment examining the impact of generative AI on teamwork and expertise within Procter & Gamble. The study involved 776 professionals working on real product innovation challenges, randomly assigned to individual or team settings with or without AI assistance.

The research investigated how AI affects performance, expertise sharing across functional silos, and the social and emotional aspects of collaboration. Findings indicate that AI significantly enhances performance, allowing individuals with AI to match the output quality of traditional human teams. Moreover, AI facilitates the creation of more balanced solutions, regardless of professional background, and fosters more positive emotional responses among users.

Ultimately, the paper suggests that AI functions as a "cybernetic teammate," prompting organizations to reconsider team structures and the nature of collaborative work in the age of intelligent machines.

• AI significantly enhances performance in knowledge work, with individuals using AI achieving a level of solution quality comparable to two-person teams without AI. This suggests that AI can effectively replicate certain benefits of human collaboration in terms of output quality.
• AI breaks down functional silos and broadens expertise. Professionals using AI produced more balanced solutions that spanned both commercial and technical aspects, regardless of their professional background (R&D or Commercial). AI can also help individuals with less experience in product development achieve performance levels similar to teams with experienced members.
• AI fosters positive emotional responses among users. Participants reported more positive emotions (excitement, energy, enthusiasm) and fewer negative emotions (anxiety, frustration) when working with AI compared to working alone without AI, matching or even exceeding the emotional benefits traditionally associated with human teamwork.
• AI-augmented teams have a higher likelihood of generating exceptional, top-tier solutions. Teams working with AI were significantly more likely to produce solutions ranking in the top 10% of all submissions, indicating that the combination of human collaboration and AI can be particularly powerful for achieving breakthrough innovations.
• AI is not merely a tool but functions as a "cybernetic teammate" that reshapes collaboration. It dynamically interacts with human problem-solvers, provides real-time feedback, bridges expertise boundaries, and influences emotional states, suggesting a fundamental shift in how knowledge work can be structured and carried out.
