An ad hoc committee has been created to decide if the launch for a new product should be continued as scheduled or delayed. The committee members are comprised of diverse decision-makers. Stan is making a plea to the committee to delay based on a hunch he has. Mary has presented a case for her recommendation based on a simplified model to reduce the complexity of the decision at hand. Caroline has carefully constructed a flow chart defining the problem, identifying the decision criteria, allocating weights to the criteria, developing a list of all the possible alternatives, evaluating these alternatives, and then selecting the "best" alternative. Which approach to decision-making is Stan using?
