Step-by-step explanation:
In the inclusive model, a triad refers to a three-member group within an organization. These groups are formed to fulfill specific material needs, and they often play a crucial role in the decision-making process. Triads can impact decision quality by increasing transaction costs, which are the costs associated with making a decision. As the number of individuals in the group increases, so do the transaction costs, making it more difficult to reach a decision.
