Yes, but the problem is that the organisations will only listen to McKinsey and they have a motivation to not solve the problem but to merely adapt it and bill the client again. Agile is one of the few significant shifts in business where the board members are unaware of the creators and don't hire them in to consult authentically. I think only Kent Beck was hired by Facebook at a somewhat senior level, and Ken Schwaber spoke at Google a couple of times for mega money. It really should be a thing where every manifesto signatory is a consultant to big business at board level.
