"Like all evaluations, advocacy evaluations can draw on a familiar list of traditional data collection methods, such as surveys, interviews, focus groups, or polling. But because the advocacy process can be complex, fast-paced, and dynamic, which makes data collection challenging, and because advocacy efforts often aim for outcomes that are hard to operationalize and measure (e.g., public will or political will), new and innovative methods are being developed specifically for assessing advocacy and policy change efforts. This brief describes four new methods - Bellwether Methodology, Policymaker Ratings, Intense Period Debriefs, System Mapping - that were developed to respond to advocacy’s unique measurement challenges."
