A friend is in the middle of reading this book, but, I stole it from him and now I'm reading it.
It's called REWORK by Jason Fried and David Heinemeier Hanssone, these two guys who started and run a company called 37signals.
Basically, its premise is that the business world is still using archaic models based on outdated technology. We have the resources and the potential to do such much more with so much less now, and this book outlines ways to capitalize on these things.
It's a fast read with lots of diagrams/word pictures, and I am about halfway through it after sitting down to read it twice.
I'd recommend this book if you have an idea for a business but can't quite seem to get momentum in getting it off the ground. Read it if you want to learn how to work more efficiently and effectively at your current job, or if you think your workplace would be receptive to some process tweaking to result in more productivity. It's a very fast, very simple, very powerful motivator of a book.
I wish EVERYONE IN MY OFFICE HAD TO READ IT. I am thinking about just photocopying pages and taping them up around here.
