I was on a team of about 25 involved in pitching a particularly large deal to a public sector client (think US state/local governments). The audience was about 50 people from different departments and agencies throughout the state and our pitch team consisted of about 6-8 very big shots + me the computer nerd. During our prep and rehearsals a "look book" was distributed which consisted of write ups on each person expected to be in the audience. It was very detailed with a career and education history of each person, a personality analysis, where their interests/passions lie both at work and personally, and what topics and key points set them off. The deck was very professional and not something thrown together, i was impressed but a little taken aback too.
