Some time ago, I had an opportunity to make a presentation to upper management about ergonomics. At the time, I was young, daring, intimidating, and a bit arrogant. I spent a lot of time gathering information, reviewing statistics, generating cost data, and examining reports. After I spouted incident rates and cost-benefits, upper management was left dumbfounded.
I thought my technically superior presentation would leave them with no choice but to green light my ergonomics proposal. Instead, I was shot down. That's because I went over their heads - I learned later that my material had been too complex and detailed. Instead of dazzling them, I baffled them.
