This is one of the best software books I've read, that's not about strictly about software. The concept of small batch sizes in particular maps really well to prototyping and agile approaches. But it gives a basis for why those approaches make sense and work. It's like quantum mechanics compared to classical mechanics...

I have not but I just ordered it. From the description, it looks like we're on the same page.

Just another thumbs-up on this one. Fantastic!
