I have written a blog post on hierarchical organisation vs. wikis for the Committee on the Anthropology of Science, Technology and Computing (CASTAC) of the American Anthropological Association, in response to their questions:
We all know that robust tools can help facilitate research, but we do not always have the time to test the latest products and processes. Here’s a place to offer advice, suggestions, and ask for help on how to tackle specific problems. What software have you found helpful for capturing data, transcribing interaction, conducting research, or analyzing findings? What problems tend to come up? Are there techniques in conceptualization, mapping, coding or other stages of the research process that you have identified as particularly helpful? Feel free to share information about what worked and what didn’t when using technology to gain insight into your projects.
