I was sceptical about Sales at first, but I love the way Richard lays it out:

You’re facilitating the buying process, and it should lead to a win-win.

It’s not a transaction. It’s knowing your product/service, and more importantly getting to know your customer, what their problems are and what they actually need.

In this, it’s very similar to what a software engineer should know, as well about what they’re building and for whom they’re building it.

Enjoy!
