Test the evidence
Use current sources, identify the population and time period, and distinguish findings from inference.
Plan implementation
Assign responsibilities, measures, safeguards, risks and review points.
Define accountability
Identify who can challenge, override, stop or revise a decision and how the public can see results.
Update when facts change
