Getting 85% percent right in strategy implementation is not sufficient when it comes to airplane product. The previous example of the A320 which crashed on early test flights shows that it is crucial that plane crash is due to human error. NY Times reports:
Until a crash inquiry is done, analysts said, Sukhoi will have difficulty marketing the Superjet. “It would be entirely understandable for any potential customer to hold off until it’s determined whether the cause was human error or mechanical failure,” said Sash Tusa of Echelon Research and Advisory in London.
While it is rare for such a young aircraft to crash, it is not unprecedented — an Airbus 320 crashed during a demonstration flight in 1988, killing three people and injuring 50. Investigators determined that the cause had been pilot error and found no evidence of a malfunction. The A320 went on to be one of the world’s best-selling aircraft models.
If analysts identify human error as the cause of the plane’s crash, most of the existing 240 Superjet orders will stay on the books, Mr. Tusa said, but “if it turns out there is some kind of major design flaw with the aircraft, those orders aren’t worth the paper they are written on.”
