We do it. Usually agile comes from above and the team only have to tick a box, say they re agile and show a shadow org around it. We even rotate the scrum master sometimes to spread the joy.

End of the day, we fill the client's need, as efficiently as we can without letting them run wild in expectations and keeping cost in line with budget: it's common sense and I dont get what the agile religions bring really. Turn idiots into mediocre people, maybe ?

We have scrum master as a rotating hat with all the other senior developers on the team. 99% of my day is code or meetings on what I'm coding. The only burden is once a week I look at jira with some managers and help them click boxes. I'm not sure what a full time scrum master would really do.

I have. Half of the time, I’m glad it’s not their primary responsibility in this case.

i have seen a scrum master code.

     ScrumMaster = NULL;

there you go !
