It is all too common to hear excuses, unfortunately many without basis or need, that are used to hide blame or ignore problems. Far better to be in an environment that accepts responsibility than using excuses for why things are not as anticipated.
“That was before my time here”
“I was not consulted on this”
“I did not know enough detail”
“there is always a significant lead-in time that we had not anticipated”
There are many more, but these are an example of an excuse culture – once in a while they may be valid, often they are not.
