I don't know the origins of the "disagree and commit" philosophy, but Jassy's use seems like a self-serving perversion of what is an attempt at dealing with decision deadlock. ... that is, disagree-and-commit transactionally seems like it ought to be between peers. Disagree-and-commit when applied between superiors and reports could be rewritten as just "shut up and follow orders."
This has been an option throughout my career, and I think many people simply don't have that option, especially early in their career.
