Dear ITIL Wizard,
Our problem is this: We are being expected to conduct root cause on problems that impacted us but which are owned and maintained by 3rd parties who will also have their own Problem and Incident teams. This means spearheading investigation and exploring ways to remedy problems at another company! It's like sorting out your mate's wife's gambling addiction because it's making YOU have to fork out for John's beers whenever you go out! No, John should be telling YOU what he's doing to sort the problem out.
