To support commercial-strength web development it is as important to utilize a process as it is in regular, non-web information systems development. Using an established OO/CBD development process (OPEN), we evaluate its efficacy in web development support and propose new and amended Activities and Tasks that should be included in OPEN in order to fully support the new demands of website construction and the delivery of business value on the web. Sixteen new Tasks are identified together with one new Activity. Four subtasks of particular relevance to the interface and based on Usage Centered Design are also advocated.
