Abstract
Within the framework of a project, a variety of known and unknown problems and difficulties in collaboration may occur, which affect how the success of a project is perceived. The goal of our research is to identify factors that influence the perceived success of a project in order to be able to take early countermeasures if project success is threatened. In this paper, we present preliminary results of a study for perceived project success. The study measures perceived project success quantitatively and qualitatively; in addition, our goal was to analyze correlations between perceived project success and aspects of collaboration, communication and individual experiences by using path analysis. The study was conducted in the context of a large-scale research and development project, where multiple partners from research and industry with a heterogeneous background work together to develop new methods and technologies in the field of "internet of things". After the first half of the project, we conducted an explorative survey with 45 persons to evaluate how the current status and project success are perceived by the partners after 1.5 years of collaborative work. As key result, we identified factors that significantly influence the perceived future project success.
