Self-evaluation judges interventions on the basis of relevance of the objectives, why an activity does or does not attain its objectives, how performance can be improved as well as on the basis of results, impacts and sustainability at the level of addressees. The EU delegation to BiH decided to resort to this project-management tool to assess the project performance of a number of projects contracted by the EUD to Bosnia and Herzegovina (BiH) in the area environment and water infrastructure under the Instrument for Pre-Accession 2007-2014 (IPA I). These projects launched from 2009 to 2015 were related to water and solid waste sectors. It covered extension, refurbishment and construction of water supply systems and production, waste water systems and treatment plant; works to prevent floods and TA to waste management. The global objective of the evaluation was to provide the EUD to BiH with sufficient information to make an informed judgment about the past performance of the selected projects (their efficiency, effectiveness and impact), to document lessons learned and to provide practical recommendations for follow-up action. This particularly aimed : • To assess in particular the efficiency, effectiveness and impact of project implementation, indicating clearly to what extent the results, purposes and overall objectives of the selected projects were achieved. • To provide comparative assessment of efficiency, effectiveness and impact of EUD interventions based on the selected projects, including strengthens and weaknesses of the different implementation methods. • To identify and document lessons learned, focusing on the design, implementation and management of the selected projects for improving of programming and identification of possible future actions under IPA II. • To provide recommendations for practical follow-up action, with the emphasis on actions related to sustainability of project benefits.
