The most common pitfalls in demoing software to customers are obvious, but people just can’t help themselves. The fundamental issues reside in whether it is a demonstration, a training session or selling the concept. Ask yourself the question -  who are you doing the demo for - you or the customer? Are you impressed by your own product or are you impressing the customer?

95% of all customer decisions are made by the emotional / irrational (sub concious) mind and therefore if you want them to buy from you - or to remember you - then you need to create moments that are memorable. Features and benefits do not do that!
