Every once in a while a great article that explains an idea well appears that is worth sharing. This is one example, from HRDQ: Five Whys vs. Fishbone Diagrams for Root Cause Analysis . The article is worth reading but in brief, it describes two powerful and commonly used root cause analysis tools and how to use them. It makes a convincing case that it is not exactly one vs. the other -- start with the classic Fishbone diagram. If you uncover what appears to be one dominant cause path, drill down on that path using the 5 Whys. That's the order: 1. Fishbone 2. Five Whys I use variations of each of these tools in our workshops on Creative Problem Solving. The common versions are still effective and will save you time in problem solving. The root cause analysis is essential. Done properly and thoroughly it will prevent you from chasing solutions that do not actually solve the problem. What problem are you working on today? Have you identified the root cause? -- doug smith
