There is an interesting article on this topic by Jeff Lash, and I wanted to share my opinion too.
Product Management and User Experience are different teams in companies — even though they work collaboratively the organization structures are completely different. Both functions are not the same — there may be some overlap but they are not the same.
Whilst User Experience is critical to any product, product success is beyond UX design. Some companies are completely oblivious to the difference and they treat both teams in a similar fashion.
UX teams have managers. UX teams have directors. UX teams have ownership too. If the UX team comes up with a design which is to the best of their ability, and if that gets poor reviews (by management, beta testers, or end users), then why should the Product Manager be held responsible for it?…
