The quality of the delivery system along with theoretical underpinnings, development strategy and country`s institutional system has decisive influence on EU regional policy implementation. Analysis of the management system of the Integrated Regional Development Programme shows that there is more weak than strong points. Main weaknesses can be described as: not transparent, politically sensitive project selection and time consuming procedures, unclear allocation of responsibility, high costs imposed on beneficiaries, low managerial skills, and, finally, conflicting solutions with existing legal distribution of powers between regional government and regional representative of the central government. Implementation effects of 2004-2005 confirm that delivery mechanism fails to meet expectations.
