Answer:
Explanation:
if the documentation is adding to the quality and maintenance of the software this is definitely a good argument for documenting every sprint. Just because that's the way it's done and we don't want change is not a good reason. Tooling that requires is also isn't. And the scrum master cannot demand this kind of things.
