“…Even though, the problem of process maturity assessment has been widely described in the literature (Becker et al, 2009;Butzer et al, 2017;Röglinger et al, 2012;Sliż, 2018;Tarhan et al, 2016;van Looy et al, 2011, Lee et al, 2007Bai et al, 2018;Moutchnik, 2015;Ormazabal, Rich, et al, 2017;Raschke and Ingraham, 2010;Tarhan et al, 2015), very little space has been devoted to the process maturity dedicated for the transport sector (Charłampowicz and Grzelakowski, 2022;Sawicki and Jaworek, 2017;Thalassinos and Zampeta, 2012). Some of the developed process maturity assessment models have general characteristics (Sliż, 2018), however, they could not be successfully implemented in inland transport companies, or the transport sector in general, due to, among others, the lack of emphasis on environmental issues.…”
