Adaptive structuration theory (AST) models the ways in which technology is adapted to an organisation and organisational structures adapt to the technology. AST has been developed through research involving technology applications such as group decision support systems and collaborative technology. Compared to these, Web technologies are both more common and more complex: Use of AST with the Web requires an extension to the basic AST model. This paper suggests that for relevance to website development there are not four, but eight structures that may be adapted: technology features, technology spirit, developers, task, staff, management, customers and visitors.
