If someone is referred to as product owner, then the individual should own the product in its entirety—like Word in the example—and not just a product part—such as the ability to save a document. Referring to people as product owners who do not manage a product and do not exercise the right ownership is wrong in my mind: It creates confusion and it sets wrong expectations: Someone who owns a product part cannot take on the responsibility of maximising the product’s value and achieving product success. Additionally, the individual does not need the corresponding decision-making authority and does not require the same skills.
