That is surely a challenge. It seems similar to the structure of how do you convince someone their position on a topic is mis-informed (not that they are wrong)

That is surely a challenge. It seems similar to the structure of how do you convince someone their position on a topic is mis-informed (not that they are wrong). Most things I've seen and read are usually focused on getting that person to explain it to you. You ask leading questions and see if they can get to a logical inconsistency thereby changing their own mind. I don't know what "issues" you are referencing but if it is a Product Manager, for example, you could try an approach of referencing external best practices. "Facebook released a template for how to perform and present market research for a new product. This was super cool. Is this something we could do for our products?"
