APER vs. Revenue Per Engineer
Adjusted Efficiency vs. Raw Productivity
RPE is the standard metric. APER accounts for debt load, innovation tax, and capital efficiency.
📊 Scoring Matrix
Revenue adjusted for debt + innovation tax
Simple: Revenue / Engineers
Factors in technical debt burden
Ignores debt entirely
Adjusts for maintenance overhead
Treats all engineering as equal
Identifies specific improvement levers
Shows symptom, not cause
Stage + vertical adjusted
Raw number comparison
Explains why, not just what
Simple narrative
📋 Executive Summary
RPE is a vanity metric. APER reveals the levers. Use both but act on APER.
Companies tracking only RPE miss 500K-1M in hidden efficiency gains.
🎯 Decision Framework
- ✓ Internal engineering optimization
- ✓ PE/VC due diligence preparation
- ✓ Identifying hidden efficiency levers
- ✓ Board reporting with depth
- ✓ Public benchmarking
- ✓ Quick executive summary
- ✓ External stakeholder communication
- ✓ Industry comparison headlines
Present RPE to external stakeholders (simple). Use APER internally (actionable). Track both quarterly.
🌐 Market Context
APER was developed by Richard Ewing as part of the Engineering Economics framework to provide a debt-adjusted view of engineering productivity.
APER adoption growing among PE-backed companies and CTOs focused on engineering economics. RPE remains the standard for public reporting.
