What is Variable

Constructs and the relationships between them are widely considered to be central to theory development and testing. Over time, information systems (IS) researchers have identified and explored an extensive set of relationships amongst a broad range of constructs. The result of these initiatives is a body of literature that can be considered to represent the cumulative learning of the discipline. Based on the premise that this cumulative learning is capable of providing valuable guidance to future theory development, the authors present a review and analysis of a large sample of empirical research published in two leading IS journals. The objective of this endeavor is to offer a broad perspective on the nature of the constructs and relationships explored in IS research and to develop a nomological network of the most salient relationships that can then serve to guide future research and to lend support to new and existing theory.
