The lecture discusses the consensus decision-making process, where group members deliberate until they all agree on a decision, instead of just going with the majority vote. First, while this method can be time-consuming, it offers significant benefits for companies. It results in better decisions because all concerns are addressed, potential problems are considered, and the final decision benefits the company as a whole. For instance, managers of a restaurant chain reached a consensus on a dress code, allowing servers to wear black shorts and skirts in warmer regions, which takes regional differences into account. Additionally, consensus builds stronger commitment among leaders because they all support the decision. This leads to better policy enforcement. For example, since all managers agreed on the dress code, they are more likely to consistently enforce it, ensuring servers wear black and not other colors.
