Primes

• Inverted-U Response
  • The engineering instance runs parallel: review intensity (reviewers per change, hours per review) drives defect-catching (productive: more eyes find more bugs) against queueing and reviewer fatigue (counter-mechanism: changes stall, reviewers rubber-stamp), so productivity peaks at an interior optimum, and a team that has been adding reviewers because "review has been working" is running exactly the "it's working, do more of it" reasoning the shape exists to interrupt.

    This sourceEmpirical study of modern code review documenting that its defect-finding and other benefits are offset by delays and reviewer load, consistent with a review-intensity-versus-productivity interior optimum.

Domain-specific

• Code Review
  • Empirical research finds benefits beyond defect discovery, including knowledge transfer, team awareness, and generation of alternative solutions.
