Re-Reading Allen Ward

On a long plane flight yesterday, I spent some time re-reading Allen Ward's Lean Product and Process Development. I had first read the book in a blitz right after I got my hot little hands on a copy at the 2007 Lean Transformation Summit. It's been a reference book for me since.

This re-reading was prompted by my attempt to introduce some of this material into the introductory talk that I do about lean product development. That didn't go over so well. There are so many new concepts embedded in that book: the entrepreneurial system designer, trade-off curves, set-based concurrent engineering, development cadence, etc - that 45 minutes of speaking time isn't enough to scratch the surface of the material. There is a lot of dense information in that book, but it may be difficult for someone new to the field to figure out how to get a toehold on this new world of product development that Dr. Ward envisioned.

The answer to "This is great - now what?" is found in the foreward at the beginning of the book by John Shook and Durward Sobek, where they describe the LAMDA cycle of learning. The act of simply Looking at your product development process - not the forms and slidesets, but at the stuff you actually produce - is a good first step, followed naturally by Asking why? Why do we repeat the same mistakes? Why do we have design loopbacks late in development? Why was one product a hit and the next one a fizzle?

LAMDA didn't make it into this version of the book, which he wrote three years before his death - he hints at it, but the idea isn't yet fully formed. Later on, Ward and his clients recognized that LAMDA supplies the necessary foundation for lean product development. An organization's ability to effectively execute the other practices depends upon the quality of their LAMDA cycles.

LAMDA is the on-ramp for lean product development. It is easy for an individual to try on his or her own to get a taste of lean product development, and build the company-specific case for it, and it is the first thing that an organization needs to spread across development if they want their lean product development efforts to bear fruit.
