সারসংক্ষেপ	Ex-ante policy appraisal is the structured assessment of the costs, benefits, risks and trade-offs of alternative options for achieving a policy objective, carried out before a decision is taken. Codified in guidance such as the UK Treasury's Green Book, it provides a disciplined framework for deciding whether to intervene and, if so, how — by establishing the rationale and objectives, generating and narrowing a range of options, appraising each against a counterfactual, and recommending the option that offers best value for public money. Appraisal is the forward-looking complement to ex-post evaluation, which judges interventions after they have run.	Cost-effectiveness analysis (CEA) is an economic evaluation that compares competing policies or programs by their cost relative to a single, common measure of effect — lives saved, cases averted, years of education gained, or quality-adjusted life years (QALYs). Rather than valuing outcomes in money, CEA expresses results as an incremental cost-effectiveness ratio (ICER): the extra cost of one option per extra unit of outcome it delivers compared with the next-best alternative. Codified in standard references such as Drummond and colleagues' Methods for the Economic Evaluation of Health Care Programmes and the US Panel's Cost-Effectiveness in Health and Medicine, CEA is the dominant appraisal tool for health and increasingly for other public programs with a shared outcome metric.
