The introduction of an online learning management system (LMS) raises a number of complex issues involving institutional responses at various levels to the adoption and diffusion of technological change. Issues include those related to governance, management and technical support, as well as to core learning and teaching matters associated with the professional development and teaching of academic staff, and the support of staff and students. This paper draws on two cycles of an evaluation conducted in one institution as "WebCT Vista" was introduced and piloted, highlighting the key issues that emerged from the evaluation. These issues are considered in the context of a selected model for examining the adoption and diffusion of information and communication technologies (ICTs) in higher education, with a view to analysing the outcomes of the initiative, and guiding future planning.
