More on 'salesmen'

I once worked in the sales arm of a computer manufacture and went through all of their sales training. What were we taught? We were taught to sell the benefits of technology to the senior executives in the organisation, to go beyond the IT department, to sell 'high and wide' within the organisation. (I afterwards used to say that as a result of this I have 'lied professionally'.) This approach was common across all manufactures and results in questions from senior users, chief executives, etc., such as 'why aren't we going to thin client?', 'I hope you will be using object orientation on this?' and so on. Is it any wonder that new approaches and technologies are used inappropriately most of the time.
