- I don't know how you read such things into my statements, must be
- the big lies of Wright that fool you. Of course you test as you go.
- Of course you change the design when you find problems. *And* of
- course you *plan* for that in your developmental budgeting and
- scheduling. If you don't and instead operate with a "success"
- orientation that everything is going to work just like you planned
- it and there aren't going to be any delays or extra expenses, *then*
- you'll fail more often than not to meet spec, budget, or schedule.
- Engineers still don't bend metal though. Most of them don't know the
- right end of a hammer to grasp. That's what you've got skilled tradesmen
- on the payroll for.
