Trigger test
Build
Set the goal
Write the outcome as a clear action.
“Submit timesheet” not “Be more accountable”
- Is it observable?
- Can two people agree when it’s done?
- Optional: Let users label their goal, it builds ownership.
Pick a progress signal
Choose a metric that moves when the behaviour moves.
- Does it update during the session or task?
- Does it directly reflect the behaviour, not just the result?
Visualise the progress
Use a visual that matches the type of effort:
Bars = building progress
Countdown = steps remaining
Streaks = consistency
- Will the audience see small wins regularly?
- Does the frame match the mental model of the task?
Flag errors
Every error flag should include what to do next.
Use short, action verbs: “Retry”, “Undo”, “Add detail”.
- Is the message ≤ 7 words?
- Is it private by default?
- Is red reserved for high-risk or compliance issues only?
Suggest one next move
Offer 1–2 helpful follow-ups after action.
Keep it brief, contextual, and time-sensitive.
- Does the nudge appear within 1 second?
- Does it disappear automatically after action is taken?
- Could it be confused with a pop-up or ad?
Adjust the frequency
Avoid overload by pacing feedback.
Bundle cues for fast, frequent tasks. Give users the option to snooze or mute.
- How many messages could appear in one hour?
- Can users control the flow without missing key info?
Match tone to skill level
New users: Use positive, gain-framed cues
Focus on wins, progress, and confidence-building.
“Nice start, you’ve submitted your first three reports!”
Intermediate users: Use neutral, balanced cues
Keep it direct, action-focused, and supportive without over-celebrating.
“One section missing. Add it now to stay on track.”
Expert users: Use challenge-framed cues
Lean into urgency, speed, or precision to keep engagement high.
“2 more to go, can you finish before 10am?”
Metrics
Log baseline numbers before drills. Then track gains.
