Progress with social protection is ascertained by means of data from censuses, household surveys, specialized surveys and administrative records, and this must be coordinated on the basis of each country's conceptual framework and policy components. While partial data is available in most countries, it needs to be further systematized and coordinated with management indicators. Chief among the various methodology-development initiatives are the cost-impact analysis developed by ECLAC for selecting the option that maximizes the impact at the lowest possible cost (Cohen and Franco, 2006b, 2005, Cohen and Martinez, 2004) and the performance-based management models tailored to social programmes promoted by the Inter-American Development Bank (IDB), World Bank and international cooperation agencies. First, it is unclear how the results are incorporated as information for decision-making and for implementing modifications to programmes.
