Moreover, the literature on B2B professional services is relatively fragmented across a range of discussions in multiple research areas, including capabilities (Janssen et al , 2018); customer relationships (Cabigiosu and Campagnolo, 2019; Casidy and Nyadzayo, 2019; Growe, 2019; Heirati et al , 2019); innovation and new service development (Santos-Vijande et al , 2013); knowledge construction (Heikka, 2020); modularity (Cabigiosu and Campagnolo, 2019; Nätti et al , 2017; Heikka et al , 2018); purchasing (Bonamigo et al , 2022; Heikka and Mustak, 2017; Nyadzayo et al , 2020); value co-creation (Kohtamäki and Partanen, 2016; Mustak, 2019); and value propositions (Baumann et al , 2017; Heikka and Nätti, 2018).…”
