  1. Duty

    The work is owed. It is finished when the client can run it without us.

  2. Discipline

    Schedules are kept. Estimates are held. Effort does not waver.

  3. Craft

    Code is written to be read. Systems are built for those who will run them.

  4. Restraint

    The plainest design that bears the load. Complexity is earned.

  5. Finish

    The work is not done until it stands without the hand that made it.
