20.500.12556/RUP-22734 Managing projects in large companies – project success factors in the crisis and post crisis period evidence from Serbia and Slovenia This paper investigates project success factors (SF) and project success criteria (SC) in large firms and aims to identify which contribute the most to project success. The results of this study are based on a survey of large firms in Slovenia and Serbia. A sample of 175 large firms is included. The Mann-Whitney test was used to compare groups across countries and between the COVID-19 and post COVID-19 periods. A comparison study of project SF and SC between the period of COVID-19 crisis and post COVID-19 is presented. Findings suggest a high degree of alignment between both countries: both prioritise user appreciation as the most important project SC and clear goals and objectives were identified as the most critical project SF. The results also show that a well-defined project management process is the most critical factor for successful project implementation. Project managers were constantly the most dominant decision makers on projects during and after the COVID-19 period. Analysis shows no significant differences between project SF and SF during and after the COVID-19 period, indicating that large companies are resilient in managing project success. Članek preučuje dejavnike uspešnosti projektov (SF) in merila uspešnosti projektov (SC) v velikih podjetjih ter analizira kateri dejavniki najbolj prispevajo k uspešnosti projekta. Rezultati te študije temeljijo na raziskavi velikih podjetij v Sloveniji in Srbiji. Vključen je bil vzorec 175 velikih podjetij. Za primerjalno analizo med državami med obdobjem COVID-19 in po COVID-19 krizi je bil uporabljen Mann-Whitneyjev test . Predstavljena je primerjalna študija projekta SF in SC med krizo COVID-19 in obdobjem po COVID-19 krizi. Ugotovitve kažejo na veliko skladnost med obema državama: zaznana je visoka prioriteta vidika zadovoljstva uporabnika kot najpomembnejšega merila uspešnosti projekta, jasno določeni cilji in naloge pa so bili prepoznani kot najbolj kritičen dejavnik uspešnosti na projektih. Rezultati prav tako kažejo, da je dobro opredeljen proces vodenja projektov ključen dejavnik za uspešno izvedbo projektov. Vodje projektov so bili zaznani kot najpomembnejši odločevalci na projektih med in po obdobju COVID-19. Analiza ne kaže pomembnih razlik med državama v času krize in po obdobju COVID-19. project large firm success crisis comparison Serbia projekti velika podjetja uspešnost krita primerjava Slovenija Srbija true false true Angleški jezik Slovenski jezik Neznano 2026-03-09 11:14:36 2026-03-09 11:14:37 2026-03-10 03:07:31 0000-00-00 00:00:00 2026 0 0 str. 79-92 no. 1 Vol. 17 2026 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2026-03-01 005.8 2683-345X 10.24867/IJIEM-404 270928131 RAZ_Bjelica_Dragan_Lj._2026.pdf RAZ_Bjelica_Dragan_Lj._2026.pdf 1 CB84C0E72166AA3D93F1CF91825B42C9 01e9e17ead0c6da2eb689cd78948523fb4ecf61fba2f89019acfdc1441f439ad c5dac155-1ba0-11f1-9e8d-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=33115 https://ijiemjournal.uns.ac.rs/images/journal/volume17/IJIEM_404.pdf 0 00c4b6a7-1ba1-11f1-9e8d-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=33116 Fakulteta za management 0 0 0
