How did Sheryl Sandberg resolve a contentious conflict between teams at Facebook?

Sheryl Sandberg resolved a contentious conflict between Facebook's product engineering and marketing teams by establishing a clear decision-making process. First, she had both teams outline success criteria and evaluate alternatives with a five-year impact analysis. She then implemented a unique approach by asking each side to argue the opposing perspective, which helped team members recognize the legitimacy of different viewpoints. Sandberg created an environment where everyone felt their voice was heard through extensive consultation. While ultimately she had to choose one alternative, her process ensured everyone understood the reasoning and felt ownership of the final decision, demonstrating that effective decision-making requires both accountability and inclusive participation.
