I have seen executives give talks without bouncing it off stakeholders. Those stakeholders include those implementing programs and those who will be carrying the message forward for the executive. Could it be ego or arrogance that makes one think they don't need feedback? Assumptions can be a chilling lesson through a surprise.
Understand the issue, explain your understanding to your stakeholders; get feedback and get the votes. If you can not get the votes before, you will not get them later, especially by berating people. There are so many sayings we have seen on stickers and office decor. Saying like "the beatings will continue until the morale improves"; and "ropes are better pulled than pushed."
But shame on people who do not speak up when asked. Salaries are earned for a job and that includes the truth of your understanding and your ability to speak up to those who need to hear it. Say it respectfully, and if not taken-then you have another decision.
I would love your thoughts on this. Have you had an experience where you were surprised?
