Document presents the so-called “Practical RIA package”, to serve to the public administrations in the Region to improve their competences and capacities in the domain of Regulatory Impact Assessment (RIA). The package is composed of a set of updated, improved and standardized templates for RIA, Standard cost model (SCM) and other analytical tools/methods for conduction of RIA, such as cost benefit analysis, cost effectiveness analysis and multi-criteria analysis (including brief explanations and practical tips on filling the templates). The administrations from the WBs may rely on these documents and embed all or some of them, into their internal RIA frameworks, in line with their respective needs.
