Therefore, accountability and transparency in public procurement is very important. For the regulation of public expenditures and effective use of the budget, not only public procurements but also efficient use of infrastructure that make up the system for public procurements should be considered. As a result, the importance of the electronic procurement processes is emphasized in this thesis. Public Procurement Authority (PPA) and the State Procurement and Supply Office (SPSO) responsible for public tenders in the Republic of Turkey are two foundations affiliated to the Ministry of Finance. However, in public procurement, both institutions have their own system, own business processes and legal obligations. Yet is it a privilege to have two different systems? To find the answer to this question, interoperable based Public electronic Procurement (PeP) system and current PeP system are compared with the cost analysis study for the Republic of Turkey. © 2015 ACM.eninfo:eu-repo/semantics/closedAccess[No Keyword Available]Conference Object24-26-September-2015
