Episode notes
Policy Is Fundamentally A Change
- Policy is best framed simply as change that moves people or things from now to a government or organisation's desired future.
- Salli Cohen's definition highlights movement, behavioural change, and that policy exists beyond government in NGOs and private rules.
Prepare Evidence-Informed Options Not Prescriptions
- Prepare evidence-informed advice that outlines clear options, risks, impacts and implementation realities within tight timeframes.
- Salli recommends turning over every stone available given the resources and deadline to inform decision makers properly.
Evidence-Informed Adds Human Experience To Research
- Evidence-informed blends research with practitioner expertise, lived experience and cultural context rather than relying only on trials or studies.
- Salli uses a surgeon's decades of field experience to show how practice reshapes judgement beyond published evidence.
