I'll give an example to illustrate. Situation: my software service stops working because it ran out of disk space. Insufficient focus on root cause: I add more disk, do nothing else, and assume it's solved. Excessive focus on root cause only: I investigate, find there's a leak where old data never gets deleted, call it the root cause, fix the leak, and do nothing else. Balanced approach: I fix the leak AND stop running at such tight margins (allocate breathing room) AND add automated monitoring for low disk space. The lesson to look for the root cause is valuable. Without it, disk space fills up rapidly and my other measures to insulate against that can only go so far. But if it's all I do, that's also bad.
