CIO Business Innovation Series. Paul DiModica, author of the book “Sell Technology: Technology Sales Is a Premeditated Sport”, talks about technology salesmen: Q: What are the top mistakes people make when selling technology? Well, first of all, most of them come to sell instead of listen. They're not prepared, and they tend to shoot from the hip. Secondly, they don't know what they're selling. Q: They don't understand their product? No, it's deeper than that. They don't understand the value of what they're selling and, consequently, can't explain its value. And thirdly, they sell technology instead of a solution. If your IT leadership team is having the same problems, then you are not alone. Learn how to solve the problem.
