Card-based Classification Evaluation method. Donna Maurer shares her technique for evaluating classification schemes over at Boxes and Arrows. Ten minutes from twenty users means that it's pragmatic, and it addresses classification specifically, instead of being part of a prototype with other issues to evaluate. Here's what you need to do this kind of evaluation:
- A proposed classification system or proposed changes to an existing system. Some uncertainty, mess, and duplication are OK.
- A large set of scenarios that will cover information-seeking tasks using the classification.
- A pile of index cards and a marker.
- Someone to scribe for you.
Looks great – thanks Donna! [ia/ – information architecture news]
