This paper examines the effect of modularity, architectural knowledge and joint measurability on joint supplier performance in multisourcing settings. In particular, we examine these relationships by assuming a moderating role for the guardian supplier. The limited, though growing, IS literature on multisourcing has hinted at the central role that the guardian supplier is assuming as a mediating sourcing model between the client firm and the supplier network. However, little is known about the effect of the guardian supplier on the factors that may improve joint supplier performance. A study of 190 client firms suggests that in the non-guardian supplier model (i.e. the client firm governs the supplier network), modularity, architectural knowledge and joint measurability positively affect joint supplier performance. In the case of a guardian supplier model, modularity and architectural knowledge no longer affect joint supplier performance; however, joint measurability still remains important for joint supplier performance. Our results hint at the importance of certain capabilities that the client firm needs to possess in order to improve joint supplier performance subject to its choice of a guardian supplier.
