“…Consequently, besides direct sourcing structures where apparel retailers directly deal with factories, apparel retailers can set up a mediated sourcing structure i.e., where a third party intermediary is in between and consolidates the demand of one or more apparel retailers and sources the garments for each of them from its supplier base [51]. In other words, apparel retailers set up different methods in the form of strategic global management departments or subsidiaries in foreign countries, which act as international purchasing offices (IPOs) [7,85,86] or employ third party (external) sourcing intermediaries such as full service providers and agents [1,6,15,33,51,52,55] who will support focal companies with the management of globally dispersed suppliers to overcome common barriers and find opportunities in their global purchasing strategy. Interestingly, not many papers can be found investigating the role of intermediaries in the apparel industry [1,6,15,33,87] and it is very striking that research still shows a lack in dealing with the role of apparel intermediaries in terms of the management of a sustainable supply chain.…”
