Be sensitive to differences in technical knowledge

Chances are that your customers have less technical knowledge than you do. Be careful, therefore, when explaining things to them. If you use acronyms, be sure you identify what the acronym means. The same acronym can mean different things, even in an IT context (for example, ASP can refer to “application service provider” or “active server page”). Be careful that you don’t make two opposite mistakes: either talking over their head or talking down to them. Keep your eyes on customers when you talk to them and be alert to cues indicating that they don’t understand. Ask them whether they understand what you’re saying, if necessary.
