I've never seen impeccable logic be sufficient to win both the heart and the mind.

The need to be thoughtful about experiment design is particularly acute within large companies, since some of the behaviors, such as having small teams and tapping into low-cost resources to maximize flexibility, won't come naturally to many people inside huge companies.

The number one thing I urge people to remember is it is all about being scientific about managing strategic uncertainty, while striking the important balance between being thorough and being flexible.

You have to make the decision about whether you want to avoid or you want to overcome the resistance.

I think the most important thing to do is to recognize the fundamentally different circumstances of pursuing growth.

Now, I worry a bit about the TEDification of the world where style trumps substance, so hopefully you have a good blend of both!

Companies get into grooves and they keep sharpening what they are doing, when in fact what they really need to do sometimes is to stop and do something completely differently.
