Fishbone (Ishikawa) Diagrams

Let’s revisit the question of “what do they really want?” I’ve been asked to solve several “data science” questions that really had nothing to do with data. But being stubborn, I usually agree to engage in these problems (as long as they are interesting) anyway. In those, cases it’s sometimes necessary to figure out the root causes of the problem you’ve been tasked with. Fishbone (or Ishikawa) diagrams are a popular, useful technique for figuring out the root causes of a problem. Here's a pretty good guide for thinking through a problem and its root causes using such diagrams.
