I have to admit that sometimes I read some of the technical response type blogs on this site and I find myself a bit like the CEO in that I simply don't understand what is being written about. On the other hand, at least I'm not bald like the CEO....
Whenever a manager says something in a meeting just say 'yes'. Yes sir, or Yes ma'am is even better. I had one manager that loved to be called 'boss'. "Yes, boss" always made him happy. Because they will keep asking you the same question until you do. So, Dilbert my friend, you've wasted your breath. Just say 'yes' and move on the next agenda item.
This brings up an important acronym, that being K.I.S.S.
Directors and Managers are most inclined to back or reject projects based on the perceived benefits vs. costs of a project. Keep the definition of the project simple and keep the benefits of the project simple, well represented and clear.
For a CEO, even a good CEO, they are potentially managing up to tens of thousands of employees and they aren't going to spend the time learning the terminology that each department or employee uses.
