Not a Manifesto. A Monday-Morning Guide.
This book is not about implementing Agile correctly. Plenty of excellent books already do that. It is about what to do in the company you actually work for: the one with capital budgets that lock scope months ahead, sprint commitments that cannot move, and a QA sign-off gate at the end of every iteration.
I learned the hard way that fighting the system because I was right about process did not fix the system. What helped was operating inside it without losing my mind, keeping my work visible, and nudging the environment incrementally when the opening appeared.
Every technique here has been tried in messy, politically complicated, QA-at-the-end environments. None of it requires your whole organization to agree before you start.
