The Scrum framework and Agile manifesto have been designed and purposed to remedy the very conditions the author is complaining about. I suggest reading up on some of Jeff Sutherland's writings and books on how he created Scrum and the reasons he did so. IMO there's a good chance the Longflow manifesto might be better formed after doing so.
