Technology Development Outsourcing: When to Join Forces With a Rival?

Journal of Operations Management, EarlyView.
ABSTRACT Knowing the challenges of collaborating with a competitor in developing new technologies, firms sometimes still choose a competitor instead of a noncompeting technology provider. To explore why, this study adopts an inter‐organizational trust view to explain the formation of a technology development outsourcing relationship.
