The Big Four have become a shadow of their former selves. They have become so risk averse that their advice is already incredibly generic and non-actionable.

I think their audit work is in a downwards spiral. Audit has become so competitive that they are struggling to find ways to make it cheaper. They have become slaves to reducing the hours booked, and the rate of those hours. To do this they substitute less experienced people all the time. You used to be able to chat with your partner about an issue you have coming up, now you get their assistant if you are lucky. By chasing 'efficiency' they have lost their value-add. Now the first time the partner has looked at your file is right before the clearance meeting, and they spot issues that should have been picked up earlier and tested on the day you should be signing. So you end up doing it all again. I'm trying to coin a term for the inneficiency caused by chasing efficiency.
