Public procurement is a specialized and multidimensional topic in the European Union. It reflects the need to liberalize markets to achieve competitiveness and efficiency. The creation of electronic systems for extending contracts across borders represents the solution to one of the remaining problems for the completion of the single market and the liberalization of international trade. The thesis approaches the issue of public procurement through the upgrading of the European Single Procurement Document (ESPD) system. It indicates the role and purpose of the system, the part of the eProcurement it serves and the extent of the interoperability it achieves. The need for the transition of the system to the newer version and the challenges facing the participating countries are analyzed below. For the upgrading of the system, the Gap Analysis methodology is applied, with the aim of studying the behavior of the system in the current situation and accurately defining the requirements and the expected result in the final situation. Based on the technical and business guides accompanying each version of the model, the gaps that arise at all stages of the development and drafting of ESPD documents are identified and then a detailed action plan is proposed for their bridging. In addition, for the practical part of the thesis, some components have been upgraded to the latest version of the ESDP Exchange Data Model (EDM), while keeping the overall flexibility of the model, so that it can respond and communicate with systems of older versions. This thesis also attempts to present some of the most important practices of designing and analyzing software upgrades, with the goal of being a possible trigger for more in-depth research on the plethora of information systems in electronic procurement.
