Conduct open and flexible policy dialogue.Lesson 4 and 5 focus on the importance of open communication—the policy dialogue—and the mechanisms by which players exchange information and work out agreements on specific policy opportunities (problem definition), and how those policy opportunities might best be pursued. Open communication must occur throughout the policy process, and if this happens then those responsible for making decisions at each step along the way will be well informed, and able to offer coherent reasons for decisions and actions undertaken.
