Something I learned from my grandfather many years ago served me well when I was an employee, and it serves me well as a business owner. "Don’t tell them what you can do. Show them what you can do!" he used to say. I’ve instilled this into the culture of our organization and it has made us a better company.
I recently did some research on what it takes to be an excellent leader. The first definition that I uncovered was written by Professor Warren G. Bennis who defined leaders as "People who do the right thing" as opposed to strong managers, who are "People who do things right." It is therefore very possible to be an excellent leader and a poor manager, and vice versa, so for this discussion, let’s not confuse the two.
When developing training tools for employees or customers, keep them short. People have a short attention span. This is especially true if you are doing webinars. You can do the webinars live but you can also pre-record them or record them as you are doing the live presentation. This will allow people to go back and review the presentation or see it if they weren’t able to attend the live session. Typically shorter webinars are better received– 15 to 30 minutes maximum. People tend to "check-out" if they are longer.
