Хорошая цитата (клиент говорит о продавцах софта):

They come in and they tell me about your products. They tell me how fast they are, how reliable they are, how they work, speeds and feeds – more technical detail about your products than I could possibly want to know….I pay you guys enough money that I want you to figure out my problems. I don’t want to figure out what your products do. You come in and look around, and you tell me how your products will fix my problems. That’s what I want.
