If you go way back up in this thread the reason given for Scrum being bad is it features estimation, which is useless because it's inaccurate, so telling me that systems other than Scrum feature estimation is not a rebuttal.

This is not really a discussion in good faith.

This seems like a strawman and not at all what I was picking up from further up the thread.

Can you tell me how I was supposed to interpret “it is impossible to do good estimation” as a criticism of Scrum, then?
