I absolutely love your comment on statistics. But on the notion that large companies specifically don't have hit or miss design or redesigns: I'd argue there's more than enough evidence to the contrary. And, personally, I find Atlassian products to be a very good example of that. Note: In this regard, I focus mainly on Don Norman's view on "design", which is largely orthogonal to aesthetics. It's cool for software to look nice. But if it's laid out in a non-intuitive way or doesn't prevent (or even provokes) user errors, it's not good design, period.
