The lean printing study is a good read and helped me a lot to get some idea of what my company faced if we started on the road to lean manufacturing. Granted, I am an RIT alumni so I might be biased.
I liked it a lot because it showed that, even though small and medium sized print companies probably won't get a huge improvement with lean compared to larger printers, changes to lean manufacturing still have the potential to help out those types of companies.
And since I am a recently graduate of RIT, I cannot get David Dodd's articles. Sucks being poor.
