Product Manager vs. Product Marketing Manager vs. Product Owner
That reminds me of the time I was heading the Product Management department of a large company. We had so many discussion about what a Product Owner, Manager, Technical Product Manager is. Their role. Their responsibilities. Endless discussion with much feelings involved about respect, ownership and so on. Nowadays I am convinced that a great company just doesn't need any PMs. It is way better to empower the tech and UX people. They have to have the ownership, the product role should be filled by one the people building things. There is no need for another role in my opinion and creates more discussions than necessary. It also reduces the ownership of other roles. My 2c at least.
