Some may find this controversial, disagree or just find it to be utter rubbish, but I believe, in the venn diagram of product management, it’s the background in user experience that truly makes the best product manager. I believe that in time, it will be UXers and UX designers or folks who came up through design that will eventually come to be the best product managers. You can have an understanding of the business. You can have an understanding of the IT. In both of those cases you’re removed from what the user are looking for and what they’re hoping to achieve with the product, and focused on the other facets of the respective discipline.
I also believe that there will be a time, when those designers have to tuck their design experience in their back pocket (design and UX thinking are likely second nature at this point or maybe that was just the case for me) and start to learn about the business and the technical aspects. This pivot is the thing that will leave some designers disinterested, some may even find it unsavory, and because of that I think that many designers will stick with their respective discipline of design, but for those who have that broad-ranging curiosity about all of the moving parts of their product I think it will be the UXer/designer that will be the discipline to lead product management.
