If you outsource, don't make this mistake

...don't tell your subcontractors that if they run into problems, you will take care of them. This decreases their incentive to succeed:

Among the least profitable jobs in aircraft manufacturing, he pointed out, is final assembly — the job Boeing proposed to retain. But its subcontractors would benefit from free technical assistance from Boeing if they ran into problems, and would hang on to the highly profitable business of producing spare parts over the decades-long life of the aircraft. Their work would be almost risk-free, Hart-Smith observed, because if they ran into really insuperable problems they would simply be bought out by Boeing.

Its not hard to guess what happened next.

What do you know? In 2009, Boeing spent about $1 billion in cash and credit to take over the underperforming fuselage manufacturing plant of Vought Aircraft Industries, which had contributed to the years of delays.
