We answer these questions with a unique, tailor-made survey of 542 firms in Norway, where entrepreneurs and firm managers are explicitly asked about their most significant relationship for the introduction of services and processes during the last three years and about how exactly this relationship emerged. We distinguish between purpose-built relationships, caused by research done in-house or on advice of other partner organizations, and serendipitous or casual relationships, resulting either from trade fairs, professional events or similar venues for networking, or from pure casual encounters outside a work relationship.
