When his team was confronted with a challenging decision, Eric liked to use a management technique he called the “rule of two.” He would get the two people most closely involved in the decision to gather more information and work together on the best solution, and usually they would come back a week or two later having decided together on the best course of action. The team almost always agreed with their recommendation, because it was usually quite obvious that it was the best idea. The rule of two not only generates the best solution in most cases, it also promotes collegiality. It empowers the two people who are working on the issue to figure out ways to solve the problem, a fundamental principle of successful mediation.
