When you got 10 minutes or less to talk to your executive manager, you are well aware of the fact that you do not have enough time to give background of the issue or request and he/she isn’t interested in nitty-gritty detail.
Instead of giving your jargon loaded intellectual talk, paint the picture with words. Try to make it little striking with some recent example. Tell how it’s going to impact him, positively or negatively (again painting a picture with words), and what you need from him.
If you are telling about a problem, tell what solutions you propose. Watch your gesture and prepare to answer the question with some facts; do not let it come to the point where you say ‘I will get back to you on this.”
Hope this helps and have a nice day ahead.
