This paper presents a meta-analysis-based technique to estimate the effect of common method variance on the validity of individual theories. The technique explains between-study variance in observed correlations as afunction of the suscep tibility to common method variance of the methods employed in individual studies. The technique extends to mono-method studies the concept of method variability underpinning the classic multitrait-multimethod technique. The application of the technique is demonstrated by analyzing the effect of common method variance on the observed correlations between perceived usefulness and usage in the technology acceptance model literature. Implications of the technique and the findings for future research are discussed.
Based on multiple-case research, this paper develops a model of strategic information systems (IS) investment in small and medium-sized enterprises (SMEs). IS investment is modelled as a function of an SME's strategic context as defined by its strategic focus, i.e. cost reduction versus value added and its market positioning, i.e. few versus many customers. The paper first investigates the ways in which IS may add value to organizations. It then outlines the use of IS in SMEs. This is followed by an analysis of competitiveness in small businesses. The paper develops an analytical model, which is termed the focus-dominance model, analyses case studies of 27 firms and reports that IS investment is strongly influenced by an SME's strategic context. Four cases are presented in order to illustrate the four different IS profiles identified. Finally, the implications for theory and practice are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
