It's part of setting goals. Expect your failures. It's a business tactic, used by may leaders in business. In Petro chemical piping and construction, we set goals that seem unobtainable, TA's are prime example. Though stress level goes up, everyone is on track "trying " to meet that goal. Many times we fail, only a boss points the finger at others when his goal is not accomplished. A leader on the other hand, will accept the failure and adapt and overcome. I've had many a word with a boss about his failure to have knowledge of how these things go together.
