I need to talk about something that’s been keeping me up at night.
We just finished our Q1 planning, and I’m looking at our org chart: 80+ engineers, 7 engineering managers. That’s 11.4 direct reports per manager on average. One of my managers has 15 direct reports. And here’s the kicker—the data says optimal span of control for engineering managers is 5-10 people. We’re not even close.
The Pattern We Keep Repeating
Six months ago, we had 25 engineers. Velocity was good. Team morale was solid. Then we raised our Series B. The board wanted aggressive growth. “Double the engineering team by Q2,” they said. “We need to move faster.”
So we hired. And hired. And hired some more.
Guess what happened to our velocity? It didn’t double. It dropped.
The Data We’re Ignoring
Research shows the average engineering manager now handles 12.1 direct reports—up from 10.9 in 2024. But the sweet spot for experienced managers is 6-9 direct reports. Why? Because beyond that, managers can’t provide quality 1:1s, meaningful mentorship, or technical guidance.
The numbers tell a brutal story:
- 83% of engineers report burnout in high-growth environments
- 22% of engineering leaders report critical burnout
- Managers with 7 or fewer direct reports score 20% higher on team engagement
- A 15-person team has over 100 communication channels—each a potential source of delay or misunderstanding
What Actually Breaks
When I inherited my current role, one of my directors was managing 15 people. Here’s what was happening:
1:1s became status updates. No coaching. No career development. Just “what are you working on?”
Code reviews stalled. Junior engineers waited days for feedback. Senior engineers burned out from constant context-switching.
Architectural decisions happened in Slack. No time for thoughtful design reviews. Technical debt piled up.
High performers left. The people who could get another job did. The ones who stayed were either too junior to know better or too exhausted to interview.
The Root Problem
We’re measuring the wrong thing. We track:
Total headcount
Hire velocity
Engineering headcount per product team
We don’t track:
Manager capacity utilization
Span of control by role level
Leadership bench strength
Time to promote new managers
We’re solving for team size instead of leadership capacity.
What I’m Doing About It
I went to our CEO with data. I showed her:
- Manager calendar analysis: 70% of time in 1:1s and overhead, only 30% for strategy
- Attrition analysis: managers with 12+ reports had 2.3x higher team turnover
- Velocity per manager (not per engineer): down 31% despite 40% headcount growth
Then I asked for something controversial: Pause hiring for two months.
Use that time to:
- Promote three senior engineers to engineering managers
- Implement manager training and support systems
- Rebalance teams to target 8 direct reports per manager
- Build a leadership capacity model for future planning
She said yes. We’re two weeks in.
The Question I’m Asking
How many of you are in growth mode right now? Are you tracking manager capacity the same way you track engineering capacity?
When your board pushes for aggressive hiring, how do you make the case that leadership infrastructure matters?
Because here’s what I’m learning: A team that scales leadership first scales engineering second—and actually ships faster.
