“…Specifically, module developments are seen as highly critical, since a modular product architecture combines a high level of complexity by containing technical, supply chain and service aspects (Novak and Eppinger, 2001;Salvador et al, 2002). Thus, module suppliers need specialised resources (Doran et al, 2007;Momme and Hvolby, 2002;Wolters, 2002). For example, modularisation brings high technical complexity (Handfield et al, 1999;Wasti and Liker, 1997), which requires suppliers to have advanced development flexibility, module understanding and engineering competences (Oh and Rhee, 2010).…”
