Field experiments have great potential for examining causes and effects in public management research. However, field experiments pose unique challenges, including developing and maintaining support from public managers and organizations. We offer a guide to the design, planning, and implementation of collaborative field experiments for scholars looking to move from initial interest to action. Focusing on five key phases of the research process, we offer, in one place, a practical guide and critical discussion of the benefits and drawbacks of co-producing field experiments with practice. Recent examples of co-produced field experiments suggest mutual benefits for public management research and practice.
