It was actually quite a funny process. originally they considered to have a sr director to present my work. At a board meeting, one tough guy challenged them with numerous details that they had no clue. It was decided I guess by those tough questions that I be the one to present to those top people. The "nasty" person was not bad at all when I did my presentation. He was actually quite supportive once he heard the full program. All sr managers at the meeting said he was at his best behavior ever.
