Participatory design of an Internet-based information system for aging services professionals.

The Michigan Aging Services System, a World Wide Web-based information system, was developed for practicing gerontologists in the state of Michigan. A participatory design framework adapted from the software development literature guided the development process. Users from Michigan's aging network participated in the development process. Design data were collected using multiple techniques. The system's content was developed with extensive input from actual users. The content emerged into four main categories: News and Current Events, General Information, Policy and Program Information, and Population Information. The system content is briefly compared to that of World Wide Web sites published by other state units on aging.
