It's a false signal

It's true that eBay did well during her tenure. And it's also true that she was a better grownup than the people running it before. But she also said that a monkey could drive the train. Would someone else have done better? Could a monkey have delivered the same results? We'll never know, but the experience at HP doesn't validate her as a business genius.

The Sun rose consistently during her tenure at eBay but we certainly don’t give credit for that.

eBay would have succeeded even if a Labrador retriever was CEO - due to everyone else’s efforts.
