While there are many papers investigating relationship development and relationship management in IMP, work conceptualising interaction remains limited. This is in particular when studying interaction beyond the level of the dyad. In this paper we shift the empirical lens from the single long-term dyadic relationship to multiple relationships studied across a short time frame. Data from a several court cases relating to the Norwegian food sector captures an intensive set of interactions across five actors over a six month period. We illustrate how boundary objects influence interaction attempts within a network. Connecting and disconnecting effects are produced in the negotiations between multiple retailers and producers as a result of the ongoing use of boundary objects.
