Introduction/background: It is highly probable that the criteria for assessing the implementation of public projects as successful will be different, depending on the point of view of the representatives of individual groups of stakeholders. In the paper, we present, after a brief introduction to the problems of design and the specifics of public projects, the results of surveys conducted among representatives of local governments, representatives of local communities (city citizens) and representatives of people professionally involved in project management. Aim of the paper: The aim of the paper is to capture the criteria and conditions for the success of public projects common to various groups of stakeholders. Materials and methods: Surveys were used as the research method and the questionnaire contained two open-ended questions. The research took the form of a direct interview. The analysis was performed using cross tables and a weighted average. Results and conclusions: Research results indicate that criteria and conditions common to all groups of stakeholders exist and the most important are the fulfillment of basic project parameters (time, quality, costs) as a success criterion, and reliable examination/identification of the residents' needs (social consultations) as a condition for success.
