IlLogica
Having had the pleasure of working for a company that had support functionality outsourced to Logica, and also initial system development outsourced to them I am amazed they still have any clients.
The sheer level of incompetency we experienced from them was amazing - down to things like rebooting the wrong server, not following server start up procedures to actually monitoring the servers - a function we paid for yet ended up doing ourselves.
And the development side - well, the system cost several million pounds, suffered severe performance issues, never actually worked properly and was eventually scrapped with Logica then being sued for failure to deliver.
ET because you have to come from another planet to choose Logica!
