If there's a problem with a plan then there's a problem with the plan. If there's a problem with the implementation then there's a problem with the implementation.
But when you bypass that entire process and go roll out a bunch of changes and efforts that you claim will be flawless and dole out no-bid contracts that balloon past their estimates despite ending in complete or near complete failures then that's entirely on the leadership that kicked it off.
There is no transparency here and it's not even possible to point to specific things that went wrong because it's effectively all undocumented and intentionally done outside of the existing systems and rules. And it happens again and again with different projects.
Each time it's the leadership's fault because they chose to step outside the normal processes and accountability leaving us with no way to learn from mistakes made during the exercise beyond "the processes exist for a reason, stop ignoring them".
