Engineering leaders have no shortage of quantitative metrics. Deployment frequency, lead time, change failure rate, sprint velocity, the list goes on. But these metrics capture what a team produces, not how a team feels. And how a team feels turns out to be a strong predictor of whether it will keep producing.
Employee Net Promoter Score (eNPS) is one of the simplest and most widely used tools for measuring employee sentiment. Originally adapted from the customer NPS methodology developed by Fred Reichheld at Bain & Company, eNPS applies the same core question to the employment relationship: “On a scale of 0 to 10, how likely are you to recommend this company as a place to work?”
One question, a lot of signal. But only if you understand what the number means, what it doesn’t mean, and what to do with it.
How eNPS Is Calculated
The calculation is straightforward. After collecting responses on a 0-10 scale, respondents are grouped into three categories:
Promoters (9-10): These employees are enthusiastic advocates for the organization. They would actively recommend the company to peers in their professional network. In engineering, promoters are typically engaged, productive, and likely to stay.
Passives (7-8): Satisfied but not enthusiastic. Passives are content enough not to leave, but they wouldn’t go out of their way to recruit others. They’re vulnerable to attrition if a compelling opportunity comes along, and they’re unlikely to generate the kind of referral hiring that strong engineering cultures depend on.
Detractors (0-6): Unhappy employees who would not recommend the organization. Detractors may be actively disengaged, and in the worst case, they can influence the morale of those around them. In engineering specifically, detractors often correlate with higher turnover risk and lower code review participation.
The eNPS formula is:
eNPS = % Promoters - % Detractors
The result ranges from -100 (everyone is a detractor) to +100 (everyone is a promoter). Passives are included in the total respondent count but don’t directly affect the score.
Example: A team of 40 engineers takes an eNPS survey. 18 respond as Promoters, 14 as Passives, and 8 as Detractors.
- % Promoters = 18/40 = 45%
- % Detractors = 8/40 = 20%
- eNPS = 45 - 20 = +25
Benchmarks for Engineering Teams
eNPS benchmarks vary by industry, region, and company size, but there are some general guidelines for engineering organizations:
- Above +50: Exceptional. This is rare and indicates a strong engineering culture with high engagement. Be cautious about complacency, even high scores should be investigated for blind spots.
- +30 to +50: Strong. Most high-performing engineering organizations land in this range. The team is generally satisfied, and referral hiring is likely working well.
- +10 to +30: Moderate. There are meaningful pockets of dissatisfaction that need attention. This is the most common range and represents an opportunity for targeted improvement.
- 0 to +10: Concerning. The balance between satisfied and dissatisfied employees is thin. Attrition risk is elevated, and the team may be experiencing morale issues that haven’t yet surfaced in other metrics.
- Below 0: Critical. More employees are detractors than promoters. This typically indicates systemic issues: poor management, technical debt overload, unclear career growth, or cultural problems. Immediate investigation is warranted.
These ranges are guidelines, not absolute thresholds. A startup in hypergrowth will have different dynamics than an established enterprise. What matters more than any single snapshot is the trend.
Common Pitfalls
eNPS is deceptively simple, and that simplicity creates several traps:
Pitfall 1: Treating the Score as a KPI
The moment eNPS becomes a target that managers are evaluated on, the metric is compromised. Managers start campaigning for high scores rather than addressing the underlying issues that drive low scores. Some will pressure their teams, subtly or overtly, to rate high. The score becomes a performance artifact rather than an honest signal.
eNPS should be a diagnostic tool, not a KPI. It tells you where to look, not how to evaluate a manager. The value is in the investigation that follows the score, not the score itself.
Pitfall 2: Survey Fatigue
If you survey your team every week, response rates will collapse and the responses you do get will be increasingly unreliable. Most organizations find that monthly or quarterly eNPS surveys strike the right balance between timeliness and respondent patience. Some teams include a single eNPS question as part of a broader pulse survey, which can work well if the overall survey is kept short.
Pitfall 3: Ignoring Small Sample Sizes
eNPS is less reliable with small groups. For a team of six engineers, a single person shifting from Passive to Detractor swings the score by 17 points. At this scale, the number itself is noise. For small teams, focus on the qualitative feedback (follow-up questions) rather than the score. Reserve eNPS scoring for groups of 15 or more where statistical patterns are more meaningful.
For meaningful eNPS analysis, aim for at least 15 respondents per group. Below that threshold, a single person changing categories can swing the score by 7+ points. For segmented reporting (by team, tenure, or role), set a floor of 5-10 respondents per segment to protect anonymity and statistical reliability.
Pitfall 4: Measuring Without Acting
Nothing destroys trust faster than asking people for feedback and then doing nothing with it. If you run an eNPS survey and the results reveal significant dissatisfaction, you must close the loop. Acknowledge the results. Explain what you’re going to investigate. Follow up with specific actions. If engineers learn that their feedback disappears into a dashboard that no one acts on, they’ll stop providing honest feedback, or stop responding at all.
Pitfall 5: Overreacting to a Single Data Point
A dip in eNPS after a stressful quarter, a reorg, or a round of layoffs is expected. A single low score doesn’t necessarily indicate a systemic problem. It might reflect a temporary situation. The trend over multiple periods is far more informative than any single measurement. Before launching an intervention based on one survey, wait for confirmation in the next cycle.
Acting on eNPS Results
Collecting eNPS data is the easy part. The hard part, and the part that generates actual value, is acting on it. Here’s a practical approach:
Follow Up with Qualitative Questions
The 0-10 score tells you the sentiment. It doesn’t tell you why. Always pair the eNPS question with at least one open-ended follow-up: “What is the primary reason for your score?” or “What one thing would most improve your experience here?”
The qualitative responses are where the actionable insight lives. A score of +15 tells you the team is moderately satisfied. The comment “I love the work but the deployment process is painful and nobody seems to care” tells you exactly what to fix.
Segment the Data
Aggregate eNPS across the entire engineering organization hides more than it reveals. Break the results down by team, tenure, role, and location. You might find that your backend team is at +40 while your mobile team is at -10. That’s a very different situation than a uniform +15 across the board, even though the aggregate might be similar.
Segmentation does require careful handling of anonymity. If a team has only four people, segmenting their responses effectively de-anonymizes them. Set a minimum group size for segmented reporting (typically 5-10 respondents) and aggregate smaller groups into broader categories.
Prioritize Based on Themes
When you read through qualitative feedback, themes will emerge. Common themes in engineering eNPS surveys include:
- Tooling and infrastructure: Slow CI pipelines, flaky tests, outdated development environments
- Technical debt: Accumulated shortcuts that make daily work frustrating
- Career growth: Unclear promotion criteria, limited learning opportunities, stagnant roles
- Management quality: Communication gaps, lack of recognition, micromanagement
- Work-life balance: On-call burden, crunch culture, meeting overload
- Team dynamics: Collaboration friction, knowledge silos, hiring gaps
Prioritize themes by frequency and severity. A theme mentioned by 60% of detractors deserves immediate attention. A theme mentioned once by a passive is worth noting but not worth a company-wide initiative.
Close the Loop Publicly
After analyzing results, communicate back to the team. This doesn’t mean sharing raw scores that might compromise anonymity. It means saying something like: “In our latest survey, tooling and CI speed were the most common concerns. Here’s what we’re doing about it.” Then actually do those things. Then report back on progress in the next cycle.
This creates a feedback loop that reinforces the value of participating in surveys. Engineers learn that their feedback leads to visible changes, which increases both response rates and response honesty over time.
Tracking Trends Over Time
The real power of eNPS comes from longitudinal tracking. A single measurement is a snapshot. A trend tells a story.
Track eNPS over quarters and correlate it with other events: organizational changes, new tool rollouts, major incidents, hiring waves, policy changes. Over time, you’ll build an intuition for what moves the needle in your specific organization.
Some patterns to watch for:
Gradual decline over several quarters: This often indicates accumulating problems: technical debt, growing pains, or cultural drift. The slow pace makes it easy to ignore, but the trend is real and will eventually manifest as attrition.
Sharp drop followed by recovery: Typically tied to a specific event (reorg, incident, departure of a key leader). If the recovery is genuine, it suggests organizational resilience. If the score returns to baseline but doesn’t recover fully, the event may have caused lasting damage to trust.
Sustained high scores: Good, but investigate whether response rates are also high. Sustained high eNPS with declining response rates might mean that detractors have stopped responding rather than become promoters.
Team-level divergence: When one team’s trend diverges sharply from the organizational average, that’s a signal worth investigating. It could indicate a management issue, a project that’s dragging morale, or a team that’s found something worth replicating.
eNPS as Part of a Broader Picture
eNPS works best as one component of a broader developer experience measurement strategy. On its own, it tells you sentiment. Combined with the SPACE framework (which captures satisfaction, performance, activity, communication, and efficiency), it becomes part of a multi-dimensional view of team health.
In CompassHQ, eNPS is calculated automatically from survey campaigns and tracked alongside SPACE category scores. The platform shows eNPS trending over time, segmented by team, with week-over-week deltas that surface emerging issues before they become crises. Surveys support anonymous, semi-anonymous, and identified modes, so teams can choose the level of openness that matches their culture.
The goal is not to optimize the number. The goal is to create a reliable feedback channel between engineers and the leaders making decisions that affect their daily work. eNPS is one of the simplest ways to keep that channel open, as long as you commit to listening to what it tells you.
