In recent period, business process management (BPM) has been increasingly a matter of interest for numerous authors as well as numerous organizations, due to the understanding of business processes as the core part of every organization. Significant efforts have been put into researching and implementing BPM within organizations. This paper's goal is to present the current state of BPM maturity and usage of social BPM within the companies operating in Croatia and Slovenia by analysing data collected by the PROSPER research group through questionnaires. Moreover, organizational culture is included in the analysis as well. Results indicate higher BPM maturity level and higher usage of social BPM within Slovenian companies than within Croatian ones and some other differences regarding dominant organizational cultures have also been found.
