“…Consequently, their approach focuses mostly on the organizational and planning, control, and information complexity in the Vogel and Lasch (2016) framework. Summarizing the different approaches in Table 1, we identify three main groups of approaches: process-/organization-centralized (Schuh, 2005;Bayer, 2010;Wilson and Perumal, 2010), product-/portfolio-centralized (Park and Simpson, 2006;Orfi et al, 2011;Hansen et al, 2012;Bauer et al, 2015;Skirde, 2015, as well as Ripperda and Krause, 2017) and logistic-/supply chain-centralized procedures (Lechner et al, 2011). The analysis further shows that procedures primarily focus on internal complexity and mostly ignore the external dimensions.…”
