My favorite quantitative metrics for engineering teams:

  • Avg time from code review requested to code review picked up
  • Avg time to complete code review
  • Avg time from eng done to first customer using it
  • Avg time from eng done to full production release
  • Fraction of tasks started that never reach a customer
