Contextual determinants and performance implications of information systems strategy planning within South African firms

While studies have shown the effect of context on IS planning as important, the incorporation of contextual factors has not been systematic and the categorization of factors has not been made explicit and some factors have only been superficially examined. My study examined the interrelationships amongst four domains of context and considered their influence on IS planning. The corresponding impact of planning on performance was also assessed. Data was collected from 116 South African companies and results revealed that the internal IS context mediated the effects of environmental and organisational level variables on IS planning practice. Results further showed that IS planning intensity and degree of integration with business planning was strongly influenced by managerial planning expertise, and had positive effects on business management's commitment to IS as well as on IS contribution to business performance. Results have important implications in organisational IS planning and performance.
