What is Dioptra? Dioptra is a web-based cost analysis tool that enables program staff at humanitarian and development organizations to rapidly estimate the cost-efficiency of their program interventions, using existing financial and monitoring data. There are two key cases where Dioptra provides the greatest value: (1) Sectoral Learning, exploring the typical cost-per-output of common activities and analyzing how their cost-per-output is driven by differences in activity design or program context. (2) Performance Management, where we analyze the cost-efficiency of a program periodically and compare to benchmarks for that activity, and assess whether greater reach might be possible if the program design were adapted.
Where does the name “Dioptra” come from? A dioptra is an astronomical and surveying instrument from the 3rd century BC. It is a simple tool used by Greek astronomers and engineers to measure the relative positions of stars, advance the science of astronomy, and achieve incredible feats of engineering. In the same way, the Dioptra cost analysis tool is a simple tool that can help to measure the relative cost-efficiencies of program interventions and advance our knowledge on ways to increase reach and impact for people in need.
