Attrition tracks the rate at which engineers voluntarily or involuntarily leave the organization over a given period. High attrition erodes institutional knowledge, disrupts team continuity, and imposes significant recruiting and onboarding costs. It often serves as a lagging indicator of systemic issues in culture, compensation, developer experience, or management effectiveness.
Rate of developer departure. Replacement cost: $50–100K per engineer.
Depends on tooling. Poor monorepo experience accelerates attrition ('monorepo hell'). Good monorepo experience improves it (consistent DX, easier onboarding, less version confusion).
AMPLIFIED: Isolation + slow feedback + perpetually blocked PRs + morning notification overload = burnout accelerator. Distributed developers who feel their velocity is throttled by timezone gaps are the most likely to leave.
Replacement cost: $50-100K + 6-12 months ramp. High turnover drives 37% more tech debt. Developer experience problems compound into attrition at scale.
Remaining devs absorb responsibilities.
37% more debt in high-turnover teams.
Fewer devs = more frequent rotations.
Departing devs take tribal knowledge.
Reduced capacity for 6–12 months.
Sustained overload → burnout → departure.
Strong predictor of retention. Teams with higher DXI scores show 43% higher engagement.
Experienced devs leave first.
52% say burnout is why peers leave.
Developers leave when they feel unproductive. Low PR completion rate signals throttled velocity.
Chronic sense of being throttled by TZ gaps erodes motivation. Devs who feel velocity is artificially constrained leave.
