How Top Engineering Teams Actually Perform
A live index of the industry's high-performing engineering orgs.
Act 1 · Performance
Baseline = 500 OSS Performance Index at its Q1 2025 (pre-AI) level. Performance is measured through the lens of a Senior Engineer.
Show methodologyHere is how fast they got there.
Engineering performance
Commits are measured by depth, not lines. Reported in ETV (Engineering Throughput Value).

Company breakdownSpeed is necessary, not sufficient.
Act 2 · Direction
Faster at what?
The same speed can ship features or rework what AI just broke.
Performance Composition
Growth, Maintenance, Fixes, as a share of performance.
Act 3 · AI Cost
What did the performance gain cost?
The gains are measured in ETV, so the cost is the tokens you spend to land one ETV in production.
AI tools Cost to ship one ETV
These numbers are for enterprise level pricing.
Act 4 · Roadmap Alignment
Is any of it on the roadmap?
Your team is shipping. You cannot see how much of it the business actually asked for.
Healthy line
75%
of your ETV should map to a declared roadmap item. Below that line, you're shipping fast in directions nobody asked for.
What that looks like
Strategy is operational. Most engineering moves a stated goal forward.
Half pointed at the roadmap, half drifting. Common, and fixable.
Most engineering doesn't match what leadership actually planned.
Low alignment is a process problem, not a people problem.
Act 5 · Patterns
Which repositories are pulling weight?
Top repositories by per-developer ETV. This week's momentum and the full quarter, side by side.
Top 5 Repositories · last 7 days
Highest per-developer Engineering Throughput Value (ETV) shipped in the last 7 days. Not normalized to a month.
