The configuration and quality of relations between non–boundary spanners and boundary
spanners is vital to the effective implementation of alliance plans. These ties allow partners
to identify and leverage those relevant tangible and intangible internal resources that boundary
spanners themselves are not aware of or have access to or control over. As a result, the
intraface strongly affects how partners address emerging issues in the alliance, that is, which
resources they (can) bring into play to tackle these issues, and ultimately how successful
they are in resolving problems over the course of the alliance life cycle.
