Practice doesn't make perfect

In order for feedback from a colleague to be meaningful, your co-worker has to know what kind of feedback you want. Are you asking for feedback on your content, your delivery, your visuals or your engagement with your audience? The mistake many presenters make is to ask for feedback after their presentation. Ahead of your presentation define the kind of feedback you want. That way, the person can take notes as you speak. The more specific you are, the more meaningful your feedback will be. If you simply say, “Tell me how I did,” your observer is likely to default to saying, “Good job.” If you say, “Please count the number of ums and ahs you hear because I want to see if I have made progress in that area,” your colleague will be able to offer you good insights.
