Managers in Technology

CTO vs VP of Engineering

CTO is responsible for the technology "vision" (future)

  • should report to the CEO
  • understands how technology fits into the larger, real world
  • responsible for the culture
  • head architect is the CTO in training
  • must be excellent at communication
