Replication is one of the main principles of the scientific method. The social sciences, and in particular the information systems discipline, has lagged behind the physical sciences which have more established traditions of independently replicating studies from other labs. In this essay, we outline the need for replication in the information systems discipline, identifying three possible approaches for executing such studies. There are numerous benefits to the discipline from embracing and valuing replication research. Replication will either improve confidence in our research findings or identify important boundary conditions. Replications also enhance various scientific processes and offer methodical and educational improvements. Collectively, these benefits will help the information systems discipline mature and prosper
