Begin with a decision
Ask what the team needs to learn. In Bloom, can someone find the plant that needs attention and recover after a mistaken tap?
Write a task without directions
Describe the situation and desired outcome in plain language. Give the participant space to choose a route and record where expectations differ.
Debrief the uncertainty
Separate what you observed from what you infer. Record what still needs testing with real content, devices or assistive technology.
