Listen to your customers, but don't always build exactly what they're telling you. This is a really key distinction around building enterprise software.
The iPad needs to catch up with Flash before I put a hand on it.
The point is that I don't design stuff for myself. I'm a toolmaker. I design things that other people want to use.
Design negotiates between technology, policy, systems, and users.

Knowing how people will use something is essential.
When you build a product, you make a lot of assumptions about the state of the art of technology, the best business practices, and potential customer usage/behavior.
