Who's "in the room where it happens"? A taxonomy and five-step methodology for identifying and characterizing policy actors.

The pragmatic and transparent policy actor identification steps presented here can guide researchers' methods for continuous sampling and successful policy actor engagement. Future work should explore the utility of the proposed methods for guiding selection and tailoring of engagement and implementation strategies (e.g., research-policy actor partnerships) to improve both "Big P" and "little p" (administrative guidelines, procedures) policymaking and implementation in global contexts.
