Përmbledhja	The Delphi method is a structured, iterative survey technique developed by Norman Dalkey and Olaf Helmer at the RAND Corporation in 1963 for eliciting and converging expert opinion on complex topics where empirical data are unavailable or insufficient. It collects independent judgements from a geographically dispersed expert panel over multiple anonymous rounds, feeding aggregated results back to participants after each round so they can revise their views in light of the group's collective position.	Multi-criteria policy analysis applies multi-criteria decision analysis (MCDA) to appraise and rank policy options against several, often conflicting, objectives that cannot be reduced to a single money metric. Each option is scored on a set of explicit criteria — economic, social, environmental, distributional — the criteria are weighted to reflect their relative importance, and the scores are aggregated into an overall value that ranks the options. Set out comprehensively in Belton and Stewart's 2002 textbook and operationalised for government in the UK's widely used Multi-Criteria Analysis Manual, the approach makes the trade-offs in a policy decision transparent and structured rather than implicit.	Policy Scenario Analysis is a structured method for evaluating how different policy interventions perform across a range of plausible future states. By pairing specific policy levers with alternative scenarios, analysts can assess robustness, trade-offs, and unintended consequences of policy choices before implementation — making it a cornerstone of evidence-based policy design in fields from climate to public health.
