‘Right-sizing’ your evaluation means selecting an evaluation approach that fits the task at hand. Considerations include what evidence needs to be generated, for what purpose, at which stage of the programming cycle, and with what available resources. For example, although there is value in conducting impact evaluations of violence prevention programmes (including randomised controlled trials), these can be costly and require extensive technical expertise. Impact evaluations may not always be the right fit for a programme; they may not be the right tool at the right time, feasible, or worth it.
Presents four principles for determining appropriate methods to measure impact: credible, actionable, responsible, and transportable (CART).
Maps questions about what programmes seek to know against possible evaluation types; see guidance on how to use the tool here.
Presents 10 reasons why impact evaluation might not be an appropriate approach according to four categories: not the right tool, not now, not feasible, and not worth it.
Provides guidance on how organisations can assess their resources, capacities, and needs related to evidence-building and evaluation.
