This article feels very straw man to me. First, the 5y I've learned and run in the last 10 years takes pains to identify a fix or mitigation at each step - not just the root. In fact for small failures and big costs, the root cause is deliberately not worked on, because analysis says the finer grain fixes are better/cheaper. Second, root cause trees have been quite common, because there's almost never just one chain, especially when you're running a system that has plugged all the easy holes and fixed all the obvious first level problems. Straw man article IMO, but I can't figure out for what purpose.
