Even a well-resourced, well-designed evaluation study is unlikely to be able to address all of the above thematic areas. Deciding what to monitor should be demand-driven, informed by the target audience and evaluation objectives as well as the thematic priorities of an organization. Similarly, the characteristics of a project or programme (such as type of intervention, scale, stage) and feasibility issues (such as institutional capacity, financial and human resources and time) are important considerations. How to evaluate? The presentation "How to evaluate?" gives a taste of evaluation design options and the use of quantitative versus qualitative methods, and addresses the importance of the size of an evaluation study.

Chafee Chairman The Honorable Max Baucus Ranking Minority Member Committee on Environment and Public Works United States Senate The Honorable Tom Bliley Chairman The Honorable John D. Dingell Ranking Minority Member Committee on Commerce House of Representatives The Environmental Protection Agency EPA has been required to perform benefit-cost analyses or regulatory impact analyses RIA to support its regulatory actions since 1971. The analyses are expected to conform to guidelines developed by the Office of Management and Budget OMB and EPA to implement executive orders requiring them. Generally the guidelines describe the major components that should be contained in the analyses such as a statement of the need for a regulation and a description and estimation of the benefits and costs for regulatory alternatives including the results of sensitivity analyses to characterize the effects of uncertainties. The guidelines allow EPA considerable flexibility in preparing RIAs. Specifically the guidelines stipulate that the scope and precision of analysis depend on the quality of underlying data the scientific understanding of the problems to be addressed through regulation resource constraints at EPA and the specific requirements of the authorizing legislation. The guidelines also recommend that the scope and precision of the analysis should be proportionate to the importance and complexity of the issues being addressed. This report which describes the results of our review of 23 RIAs supporting air quality regulations is addressed to you because of your jurisdiction for the Clean Air Act. These RIAs were prepared .
