GDS moderated usability session
A moderator observes users attempting realistic tasks without revealing the intended path.
documented-procedure · conventional-workflow · Source account, not a validated implementation
What goes in
- Research questions
- Service or prototype
- Task guide
What comes out
- Task observations
- Usability issues
Documented sequence
Order described in the source account; not a sequence between pattern families.
- Agree questions, users, and service scope
- Prepare accessible sessions and note-taking
- Design realistic tasks without answer clues
- Pilot the discussion guide
- Introduce the session and tasks neutrally
- Observe and invite thinking aloud
- Clarify uncertainty and ask closing questions
- Secure research material
Checks described
- Pilot instructions
- Consistent task delivery
- Neutral prompts
What changes with context
- Method requires actual or likely users; personal-data safeguards apply
- Dummy data is an option where real-data use is unsuitable
- Assistive-technology users may need their own setup
Shared patterns · provisional interpretation
-
Investigate needs through inquiry
Uncertain needs or situation → questions, responses, and a progressively clarified account
-
Test alternatives and learn
Hypotheses or alternatives → deliberate test, observed results, and updated selection or next action
Fit: direct. Exploratory analyst coding of collected source summaries; not independently tested
Could this transfer?
Hypothetical: a logistics team could test whether a new dispatch checklist is understandable using fictional orders.
Limit: Artificial tasks and dummy data may miss real contextual problems.
Evidence limits and unknowns
Summary through context_constraints paraphrase source-backed mechanics. structural_motifs, candidate_midlevel_pattern, transfer_example_explicitly_hypothetical and transfer_limit are analyst interpretations, not tested findings.
- Task-specific success thresholds
- Results from any particular service
Source eligibility and effectiveness
Allowed use: process reference with explicit limits . Source eligibility is not proof of effectiveness, safety or transferability.
