Many thanks to everyone who emailed me with details of books I missed from my lean manufacturing reading list. To pick out just a couple:

“The best source on ‘lean’ (in the broad sense) for product / software development is Reinertsen’s Managing the Design Factory. It’s fantastic. Lot of Mary and Tom’s stuff is from it.” — Clarke Ching

“Thinking Beyond Lean is about the product development model of car manufacturers and how Toyota completely overhauled their product development process, at a time when some of their competitors were starting to copy Toyota’s process. See here for a first stab at mapping the ideas in the book to agile software development.” — Pascal van Cauwenberghe

Any others you can recommend?
