Expert review of administrative data from public procurement monitoring systems and data presentation facilities, and data from publicly available sources. Interviews with contracting authorities, economic operators and their associations, procurement experts and NGOs. As a minimum, the review would look for the following: • A clear and concise presentation of public procurement data by the central system is achieved if the annual reports discuss the development of spending volume, intensity of competition and market concentration, use of different procedure types, speed of administrative procedures, cost overruns and delivery delays. • The system displays public procurement data in a clear and simple format if a choice of display and presentation modes is available. A simple data display format entails, at a minimum, that the same information is reported consistently in the same way. • The system facilitates retrieval of information (including for external analysis) if it has a function for searching notices. At least five search criteria must be included: e.g. notice type, contracting body type, time period and free text search in the notice text, or geographical location. For each of the following five criteria for the central system (electronic portal), 2 points are awarded (total of 10 points).
