>but to lead a product’s development

My guess is--haven't really been a PM for other types of products--is that the relationship between the PM and engineering is probably different. I would certainly never have considered that I "led product development." And, yes, I did bring in requirements both from customers directly and from sales and I worked closely with engineering on defining the product. But actually--remember that product development cycles of big hardware were relatively long--after the initial requirements and basic design were worked out for a given system model--there often wasn't a huge amount for me to do until closer to launch when a lot of selling/marketing/pricing/etc. tasks had to get done. (I tried to plan my longer vacations during the quiet periods.)

To be clear, I wasn't just sitting around for months at a time as I was usually handling multiple products and involved in exploring new areas.

>if you can’t see the product from a customer standpoint?

As far as customers are concerned, big systems have a lot to do with specs, features, pricing, upgradability, etc. (And the availability of software.) They're not even maintaining them themselves.

You brought up good points where for B2B and big corp type of product development requires different best practices. Also the politics from big corps or in B2B environments are very different than B2C. As simple as reviewing if you product via Google Analytics funnel can work for B2C, that may not apply vis-a-vis to B2B products. You can still use analytics to review, but usually the corporations are already focusing on another features and there is never enough time to revisit past products nor the budget to improve existing ones. Then, what does a PM should do?

Open source is also a somewhat different situation that I'm familiar with but not as a PM. Obviously it varies depending upon the degree to which the project overlaps the product, but a company may be more in the position of influencing a community than dictating a product roadmap.
