In the Republic of Croatia, public procurement is an area that is increasingly developing both from a legal and an economic point of view. The public procurement center is a public procurement procedure whose formal procedure is regulated by the public procurement act and other by-laws in the field of public procurement. The public procurement act is fully aligned with the acts, ie the EU Directives, and has been amended twice in 2013, and the last major change occurred in the 2004 Constitutional Court Decision when certain provisions of the public procurement act were abolished. With the aforementioned amendments certain provisions of the law became more flexible and thus facilitated the treatment of contracting parties, but also of potential tenderers in public procurement procedures. There are several types of procedures for public procurement in the Republic of Croatia, whose selection depends on the contracting authorities themselves, but also on the legal provisions which, for certain types of proceedings, have determined that they can be used only in certain circumstances. The quality of the public procurement procedure, while respecting all the principles of public procurement, in particular the principles of transparency and economics, in the circumstances that are currently in the Republic of Croatia, can restore public confidence in the system, ie in a fair and rational budget spending system. Lastly, a unified procurement system is increasingly being developed, which is also important in terms of saving and developing good practices. Recently, there is great importance to quality management in the public procurement system, which is a key anticorruption system. It is imperative to implement a quality control system with self-control and bug fixes in the system so that the public procurement system at universities is as transparent and quality as possible and that the end users will be more satisfied with the purchases. The aim of the doctoral dissertation is to present the quality management system as a very important part of the public procurement system at public universities in Republic of Croatia by conducting empirical research and providing recommendations for future researches as well as for realistic actions in the field of research.
