The Beer Living Lab was the first of a series of living labs established to analyse and improve complex cross-border trade and logistics challenges using innovative information technology. Unlike stable inter-firm networks where roles are formal and explicit, role taking and role assigning in the Beer Living Lab was highly dynamic. Although project deliverables were formally assigned, in practice responsibilities emerged as a result of actors’ own initiative or as a result of negotiation and sense-making. Even leadership behaviour shifted throughout the various stages of the initiative. The practice of knowledge broking and cultivating a close working relationship with the operational manager emerged as crucial for creating and sustaining the social network which in turn stabilised the hybrid network organisation. We discover (yet again) the key practices of knowledge brokers and the necessity for social involvement in overcoming discontinuities within organisation networks.@en
