Does Agile work in ELT print publishing?

Two years ago, ELTjam asked whether it was possible to produce an ELT course book using Agile workflows in the strictest definition of the term, creating lots of discussion. At emc design, we’re starting to see our clients use many different approaches to new courses, some using agile-inspired techniques. But can traditional ELT print publishers take ‘true’ Agile on board sustainably? Is it possible to approach a print product in exactly the same way as we approach digital products? Or are they just too different?
