Abstract:

Field methods are a collection of tools and techniques for conducting studies of users, their tasks, and their work environments in the actual context of those environments. The promise of such methods is that they help teams design products that are both useful and usable by providing data about what people really do. This paper reviews ways to adapt these methods to practical constraints, with brief case study summaries.
