This paper considers the suitability of traditional IS development methods to Web-based information systems. A two year e-commerce development project is used to explore Web-based IS development using action research. To distinguish the project from consultancy a framework of ideas – Multiview - is declared and tested in the research process. Multiview was defined in 1985 and has been since refined to become an influential approach to information systems development. It has soft and hard aspects and, as a contingency approach, is not prescriptive but adapted to the particular situation in the organization and the application. The differences and similarities of traditional IS development projects and Web-based projects are reported and found to be more about concrete differences of methodology content than abstract concepts. The project also provided an opportunity to reflect more generally about the role of methodology in IS development.
