Useful reading. What might further help is to perhaps have a description around each of the defined roles especially some ambiguous ones which may be used very differently across organizations. For example, I know how the Product Owner role is generally used across organizations and I agree that it isn't ideal to have such a role but I also know that at some places for very large and complex products, the product owner is essentially someone who 'owns' the whole product with many product manager working with him in the team who own the sub-products within the main product.
