Documentation is not a source of truth. Scrum reports = documentation. Sources of truth are: the implementation, the business, customer satisfaction. And if you want to go deeper: technical debt, developer satisfaction, developer retention. The more distracted you get with planning, the worse your product becomes and the more disempowered your developers become. Scrum can work only if it is kept down to earth. But as soon as product managers stop meeting with developers, you have entered the path to technical bankruptcy. Scrum is meant to promote collaboration between product manager and developers, but in most cases, product managers get away with avoiding this responsibility. And the reason is because scrum does not have provisions to keep product managers accountable... Scrum does not define real deliverables for product managers, therefore in practice it becomes the opposite of what it promotes.
