“In this column, I’ll summarize and compare the latest generative and evaluative methods for IA user research. The methods I’ll examine include open card sorting, Modified-Delphi card sorting, closed card sorting, reverse card sorting, card-based classification evaluation, tree testing, and testing information architecture with low-fidelity prototypes. I’ll cover the advantages and disadvantages to consider when choosing between these methods, when it makes sense to use each method, and describe an ideal combination of these methods.”
