>>The printed book will be linear with the option to skip to required sections.
It's not just a matter of subject material being presented in a linear fashion, but conceptually linear. In the introduction we do say that readers can jump to any point. However, to accommodate educators or learners who don't have much experience in learning object creation, I think the OER lifecycle needs to be fairly simple (but as you say, only simple enough) for them to understand.
I have also posted more on "thoughts on structure" Talk page.
Thanks for the comments. I have edited this page substantially, ... please check that I have not deviated too much from the style.
