Answer:
Behavioral decision making.
Explanation:
Behavioral decision making refers to the idea that leaders can influence the outcome of a decision or a process by influence other people's behavior. According to this concept, a leader should not only take decisions, but also must take action in a way that the behavior of the group changes in a way that benefits the whole group.
In this example, Kevin feels that the formal enviroment of the board room stifles discussion and creativity. By meeting with his group at a restaurant, he feels the more informal setting leads to an enviroment where the behavior of the group changes: they feel more at ease, leading to a more open communication and exchange of ideas. This is an example of behavioral decision making.
