I work in sales at a software company providing enterprise solutions. Sometimes, I don’t have a clue what I’m selling. How can I sell something to clients that I don’t fully understand? The product range is so complicated that I tried many times talking to the developers to make it more user-friendly. The language they use is completely alien to the salespeople here. The boffins don’t seem to care whether what they are creating is sellable and appealing or not. What is the best way to deal with developers like them?
