Two case studies of real world competitive advantage, followed by a question: was this a moat or not?

Most companies skimp on process improvement. But the surprising thing is that they do so not because they're bad or lazy — but because there are system dynamics that prevent them from doing so. We take a look at what those are.

The iPod marked Apple's first successful (albeit tentative) entry into consumer electronics, and laid the way for future products.

What a question about growth marketing tells us about expertise — and why expert-novice differences are so useful to probe if you're a practitioner.
