Product people get excited about solving problems that make people’s lives better. On that we can all agree. It’s the approach we choose to achieve that goal where differences arise. Sometimes the differences are significant and obvious – Agile vs. Waterfall, for example. Sometimes, they seem much less so. Take user-centered design vs. human-centered design. Aren’t users of our products human? Of course they are, but there’s more to the difference than a mere distinction.
