The development patterns of nations feature multiple dots, each with distinct histories, geographies, and characteristics. Connecting these dots, according to evaluation findings, is key to getting good results from various interventions. These important links fall into three categories. The first is horizontal, across areas such as education and employment; water supply, sanitation and health; and roads and the environment. The second link is vertical, going from inputs or initial interventions to the more final outcomes—for example, from immediate relief and reconstruction during a natural calamity to incorporating preventive measures to deal with recurring disasters. The third is a time dimension that distinguishes the differing impact of similar interventions over time or the differing ways in which the past connects to the future.
