In the moment of taking responsibility (or not) finding someone else to lay the blame on is easy and (at least in my experience) we do it all the time:
- we couldn’t deliver because the other team didn’t give their input on time.
- I achieve my part of the Sprint Goal, but Paul did not.
Well, it’s an easy excuse to stay smelling like roses…
An alternative would be to blame it on thy system and JUSTIFY your on part.
