The Lean user guide

It was suggested I read The Lean Startup, by Eric Riess. This book outlines how principles of Lean manufacturing can be applied to startup businesses, and software businesses in particular. For startups, it’s about how to figure out the right thing to build – that people will pay for – as quickly as possible. I’m still reading it, and so far, it is very good.

It begs the question:

Where does user documentation fit in a Lean startup, and can the principles of Lean be applied to User Assistance?
