Abstract:

Design organizations inevitably run across the debate of Visio versus HTML wireframes. The decision for one over the other is never a clear-cut one since, as with all things IA-related, it depends. This article seeks to sort out the issues by describing the pros and cons of each and identifying situations where one may be more effective than the other.
