Take some managers: not every kind of manager is good for this experiment, you’ll recognize the good one reading this post.
Put them in a meeting room.
Choose a presentation: no matter the topic, just pick a topic they don’t know!
Start the presentation.
After two slides, the first manager will interrupt you and start saying something.
Then another one will disagree and tell him his vision.
Then another one will interrupt and tell everyone his particular experience.
After 30 minutes you’ll be always on the same slide.
I’d really like to start some kind of meetings saying: it is NOT necessary to say something in this meeting, please don’t feel obligated to do so. And I’d really like to finish email writing: it is NOT necessary to reply to this email, please don’t feel obligated to do so.
P.S. To tell the truth I know a lot of technical guys who suffer of the same disease 🙂
