alt Hacker News> This is absolutely not true. If I can’t check in a fix or a feature because someone else isn’t doing the review, it’s definitely still my problem
It isn't. It's your scrum master's/Manager's problem, because the ticket is blocked in review.
In the meantime you moved on to another task. Because the review is not your problem.
If I told my manager it was his problem to get my code reviewed, he would tell me to do my job.
Offloading responsibility for getting code through review to a manager or scrum master sounds at least as dysfunctional as people avoiding doing the reviews.
