For the sake of argument, let's assume that you and your Scrum Master peers were all top of the class and genuine in your understanding of development and desire to help facilitate project success and never acted in a self-interested way. That's a fairly big assumption, but let's roll with that.

And maybe, a really solid big-tech company with great people who "get it" can largely make Scrum work "well enough". I'm sure you oversaw a lot of products shipping successfully.

Was that because of Scrum, or in spite of it and you might have been even more successful doing something else?

Overall though, I think you recognize how Scrum might devolve in many typical situation, right?

PS: To make it clear, no disparagement is intended in anything I said or say even though the consequences of that might seem like an attack on your profession.
