What Is Engineering Efficiency

Engineering efficiency isn't about shipping more features per sprint. It's about shipping value per unit of engineering effort. The primary obstacle is the Sync Tax, which acts as a non-linear multiplier on all technical work.

A team that looks productive on the surface may be deeply inefficient. They ship features, but each feature takes twice as long as it should because the system fights them. They hire more engineers, but velocity stays flat because coordination overhead grows faster than capacity.

Measure efficiency by tracking cycle time, deployment frequency, and change failure rate alongside Sync Tax cost. If Sync Tax is rising while output is flat, you're losing efficiency regardless of how busy everyone looks.
