I came across "Guest Blog: Finding Science and Success with Lean Principles in R&D" by Norbert Majerus of Goodyear on the Factory Physics website, and it describes the Factory Physics ideas as applied in new product development, and I thought it was a pretty good summary. This is also a lot of what we do with Theory of Constraints concepts applied in product development (and project management) arenas too.

Never Split the Difference: Negotiating As If Your Life Depended On It by Chris Voss was recommended by a couple colleagues.  This is a great book on negotiation (and a bunch of related topics). Voss and Raz start each topic with a life-and-death hostage negotiation and then delve into the ideas behind the topic and where these apply in the less dire scenarios people face every day.  The authors use Voss' own experiences in the FBI as the lead international kidnapping negotiator, his research and studies into what makes negotiations work (or not), and his teaching and consulting work.  These elements are combined in a fairly engaging style: starting each chapter with a hostage situation made me want to keep reading to find out what happened, ... and learn a lot along the way.  

Unlocking Innovation Productivity

Unlocking Innovation Productivity (Proven Strategies that Have Transformed Organizations for Profitable and Predictable New Product Growth Worldwide) by Mike Dalton is a guide to the challenges of product innovation and how to overcome them. He provides seven cumulative strategies to improve innovation, all based on Critical Chain Project Management and the underlying Theory of Constraints. 

Another tool to help knowledge workers get to what they need quickly. I've been trying Atlas Recall over the last month.  The general idea is that it sits on your computer (Mac currently, Windows soon) and keeps track of everything you see. And then if you are trying to recall "where did I see X", you can ask Atlas Recall for help. It does exactly that: will show you what you have seen, whether it was on the web or in a chat session or in documents you've been writing / reading.
