I've worked for Accenture (for way too long) and they can be characterised by a single statement that they make to the client when all is said and done and the client complains about the steaming pile of shite that was delivered:
"But in this signed contract here, there is no requirement that says our software should work".
Come on, every serious software engineer knows they are full of it.
My worst experiences always come from working with Americans and I don't come to the conclusion that all Americans are incompetent.
All we know about accenture around here (which is not the USA) is that they are good at covering their ass and the actual users of the stuff they produce are never happy.
Source: I used to work for a consultancy company. Might do so again, the work is more diverse and the pay and perks are much better than 'regular' companies.
It doesn't matter a whole lot if the contract was successful or the managers got their bonus for on-time delivery or the budget forecasts were correct, a crap product is a crap product.
