A 3-part framework describing public policymaking processes.
![[Pasted image 20260421211808.png]][^1]
- Problem stream
- Indicators: data showing a condition's magnitude or change
- [[Focusing event]]: sudden events that dramatize a problem
- Problem broker: framing the problem in an effective, emotional, values-based way[^2]
- Feedback from existing government programs
- Policy stream
- Policy communities / primeval soup: specialists generate and refine ideas
- Softening up: repeated exposure, slowly moving the [[Overton window]]
- Selection criteria: budget, technical feasibility, value acceptability
- Policy entrepreneurs: actors who invest time, reputation and capital to promote policy changes. Elected officials, academics, think tanks, industry actors, activists
- Politics stream
- National mood
- Organized political forces: industry, advocacy orgs
- Government politics: elections, administration changes
When a topic hits all 3 streams, a **policy window** opens, and policy entrepreneurs will often use that to push policy.
