“…Growing out of multiple research disciplines, this research field consists of multiple, inter-related subfields including Procurement (Iyer 1996, Hunter, Bunn et al 2006), Supply Chain Management (Larson and Halldórsson 2002, Burgess, Singh et al 2006, Wieland and Wallenburg 2013, Wieland, Handfield et al 2016), Purchasing and Supply Management (Spina, Caniato et al 2013), Sourcing, Purchasing, Contracting and Buying (Cardozo 1983, Wilson, McMurrian et al 2001, Barclay and Bunn 2006, Juha and Pentti 2008, and more. This field's theoretical development has its roots in purchasing and sourcing, and it has over time moved towards Supply Chain Management and a focus on whole supply chains (Kırılmaz and Erol 2017). At the same time, the field has moved from a predominantly operational focus to a focus on strategic issues (Spekman, Kamauff et al 1994, Anderson and Katz 1998, Bozarth, Handfield et al 1998, Lidegaard, Boer et al 2015 and proactivity (Smeltzer and Siferd 1998).…”
