An article on Jony Ive, the head of design at Apple Computer, in the New Yorker Magazine from February 23, 2105 touches on how the late Steve Jobs gave constructive feedback:
“Jobs’s taste for merciless criticism was notorious. Ive recalled that, years ago, after seeing colleagues crushed, he protested. Jobs replied, ‘Why would you be vague?,’ arguing that ambiguity was a form of selfishness: ‘You don’t care about how they feel! You’re being vain, you want them to like you.’
Ive was furious, but came to agree. ‘It’s really demeaning to think that, in this deep desire to be liked, you’ve compromised giving clear, unambiguous feedback,’ he said. He lamented that there were ‘so many anecdotes’ about Jobs’s acerbity: ‘His intention, and motivation, wasn’t to be hurtful.'”
Steve Jobs. More German than American logic.
