I think it really depends on who is the audience. If you are talking to technical or engineers, It is hard to manipulate them on the technical part of the product. you have to be honest when you present the idea, I have seen a lot of overpromising from sales members that cause to lose a project. of course, the customer relationship is an important factor for sales members, but also we are in a very competitive market. If you have a good product and market in the right way you can combine and possibly win a project. So I think there is more manipulation when it comes to C level and desition makers and it depends on the personality, Some people are open for better product or price and some are just will just keep buying the same thing because of a relationship with a company or a sales member that they like.
