I often write about the importance of alignment in goals between IT and vendors and how critical it is to avoid getting advice from those that you are not paying for that advice, because that makes them salespeople, basically the importance of getting advice and guidance from a buyer’s agent rather than directly from the seller’s agent. This leads to questions about bias; clearly the idea is that a salesperson is biased in a way that is likely unfavourable to you. But, it should be obvious, that all people are biased.
