Cool. My current client is even opposed to slightly tailoring - so, of course the teams are doing it covertly!
Is the book addressing items "outside of the project team", such as portfolio management, overall architecture, etc.?
Where would Agile values (feedback, communication, simplicity, courage, respect/humilty) be covered - seems at first blush to be just practice focused.
Cool. I think this should be your book cover.
Would "tailoring" of a practice for the organizationbe part of this? Is that what is meant by adaption? What about tailoring per project?
