Public procurement capabilities as engines for collaboration and enhanced performance in complex projects
本文通过巴西军方复杂军事项目采购的案例研究，发现公共采购方需具备管理招标、处理审计关系及跨项目知识管理等能力，才能与私营供应商建立信任协作，同时实现运营绩效和政策目标。
Purpose This paper explores how public buyers' capabilities promote collaboration with private suppliers to obtain enhanced performance in complex projects. Design/methodology/approach The authors conducted two case studies on the procurement of complex military projects by the Brazilian armed forces involving public buyers and private suppliers. The authors followed the Gioia methodology to inductively analyze data from interviews, official documents, media articles and project meeting notes. Findings The authors identified public procurement capabilities that are antecedents of collaborative trust-based relationships with suppliers in complex public-private projects. The authors unpack these capabilities in three subsets: abilities to manage the bidding and contracting process, to handle relationships with prominent stakeholders, such as audit control bodies and to manage knowledge acquired within and across current and past projects. By developing these capabilities, public buyers can build collaborative trust-based relationships with suppliers, which enable the conciliation of operational performance (i.e. on-time delivery, budget and scope compliance) and policy goals (i.e. inclusion of local suppliers in supply chains). Originality/value The authors extend the literature on the enablers of trust and collaboration in buyer-supplier relationships by providing a detailed account of which capabilities are necessary on the buyer side in complex projects, especially when accountability standards create barriers for collaborative practices. The authors also reinforce the importance of the operations and supply chain management scholarship in policy debates by showing how buyer-supplier interactions can create value in complex projects with public and private sectors.
