Unfortunately a lot of product manager roles are hired based on how many new products/features that person launched, and not the actual impact to the company or customers (that information is usually confidential or impossible to tease out from one product anyway). In reality the Product Manager roles should often be to nurture products to perfection over the long-term, and to be an absolute expert on the category. Often though those people who want to nurture great products over the long-term just go on to start their own businesses! So the field is left with flashy people who launch flashy products very often, but who don't really understand the business, the industry, or their customers.
