Quick answer: Engineers don't see their cumulative impact until it's pointed out. A simple dashboard of 'bugs closed this week' per engineer builds healthy momentum.
Visibility is motivation. Engineers who see their impact stay engaged.
Per-engineer leaderboard
Bugs closed per week; smoothed. Trend, not comparison.
Severity-weighted
Sev-1 closures count more than sev-3. Quality of work shown alongside quantity.
Show team total
Aggregate over the team. The team's overall momentum is the bigger picture.
Celebrate the wins
Slack channel post each Friday: 'this week we closed X bugs, including Y'. Visible recognition.
“Visibility and recognition are cheap. The motivation effect is real.”
Don't tie leaderboard data to performance reviews. Visibility builds momentum; performance ties build resentment.
