Effects this model doesn't captureShow
  • Hiring time. Weeks of senior-engineer interview hours and offer cycles.
  • Bad-hire risk. Industry data puts a misfire at 30% to 200% of annual salary.
  • Mentoring overhead. Five to ten hours a week of senior time during ramp.
  • Redundancy exposure. CoderCo cost stops the moment billing stops.
