What NOT to Measure in Your ERG Program (And What to Track Instead)
Most ERG dashboards are full of vanity metrics that look impressive and decide nothing. Here's what to stop tracking — and the small set of metrics that actually drive decisions.

The short answer
Most ERG programs measure the wrong things. They track numbers that look good on a leadership slide and tell you nothing about whether the program is actually working. The fix is short: stop measuring activity, start measuring engagement and outcomes.
What to stop measuring
1. Total ERG membership
The most-cited ERG metric and the least useful. "We have 4,200 members across 12 ERGs" tells you nothing about whether anyone shows up, whether members feel a stronger sense of belonging, or whether the program is producing anything. Joining a Slack channel is not engagement.
2. Number of events held
Event count rewards motion, not impact. A program running 60 events a year with 8 people per event is in worse shape than one running 12 with 80 — but the dashboard makes the first one look like a winner.
3. Slack/Teams message volume
High message volume often correlates with chaos, not health. Active leadership debate, off-topic channels, and venting threads all inflate the number. If you want to measure this surface, use engagement on communication platforms — not raw volume.
4. Social media impressions / hashtag use
External vanity. Useful for marketing reports, not for program decisions.
5. Number of ERGs launched
Launching more ERGs without cleaning up the existing ones is how programs end up with 15 ERGs and 3 functional ones.
6. Diversity demographic counts dressed up as ERG outcomes
ERGs influence belonging, retention, and engagement — they don''t change the demographic makeup of the company. Reporting "we hired X% more underrepresented employees this year" as an ERG win is a category error, and a legally risky one. See the 17 legal considerations.
What to measure instead
Three layers, in this order:
Layer 1 — Engagement
- Member Engagement Score — is the average member actually participating?
- Event Engagement Score — are the events producing value per attendee, not just per invite?
- The ERG Metric Triangle ties these together.
Layer 2 — Operational health
- ERGs with a documented blueprint.
- ERGs running on repeatable processes, not founder energy.
- Leadership transitions completed without the ERG collapsing.
Layer 3 — Outcomes tied to the blueprint
- Per-ERG: did this ERG deliver what its blueprint said it would this quarter?
- Program-level: the 7-step framework.
- The most important success metrics for your stage.
The rule of thumb
If a metric goes up and you wouldn''t change a single decision because of it — stop reporting it.
That single test will cut most ERG dashboards in half. The remaining half is the part that''s actually doing work.
What to do this week
- Pull your current ERG dashboard or last leadership update.
- Cross out every metric that fails the rule of thumb.
- Replace the crossed-out lines with Member Engagement Score and Event Engagement Score for your top 3 ERGs.
- Run the new dashboard next quarter and compare what changes in the conversation.
