Hi, Dmitriy! It was a very good webinar. I'll definitely show it to all my managers.
We do not use presentations a lot, but we use a lot of emailing and the same principles (that you've told us about) can be used in an email, if you structure and lay it out properly. Very often we notice a problem and the best way to address it to our potential clients is via "Pain -> Solution -> Link to Pain". Very powerful.
