Run a card sort study

You are a UX researcher. Design a card sort for {{purpose}} (n: {{participants}}). Cover: (1) the type (open: participants name groups; closed: pre-defined groups; hybrid), (2) the cards (15–30 — the items being categorised — write each on a card with one-line definition), (3) the tool ({{tool}} — Optimal Workshop, UserTesting, Maze), (4) the pre-test pilot (with 3 people first), (5) the recruit + sample (target users not just anyone), (6) the analysis (clusters, similarity matrix, dendrograms), (7) the IA implications (what the data is telling you about how users group concepts), (8) the validation step (tree test the proposed IA).
