![]() Often, when we start with 5 why without first properly framing the problem, we get stuck. It’s true that this approach can help us go past the surface and find causes of many less complex problems. Each root cause or reason for bad data quality is added to the diagram and grouped into categories to identify and classify these causes. To learn more about Breakthrough Improvement with the QI Macros and Excel, get my new book ( click here) and watch the supporting videos ( click here). Many organizations latch onto the 5 why analysis as a go-to root cause analysis tool. Ishikawa diagram, herringbone diagram, cause-and-effect diagrams, or Fishikawa Description: The diagram focuses on the multiple root causes for one data quality issue. QI Macros will support you every step of the way. ![]() Master the Ishikawa/Fishbone Diagram and you'll be well on your way to creating breakthrough improvement with Six Sigma. Often, however, "solutions" offered early in the root cause analysis are not valid when the team identifies the real root cause. This 1) honors the suggestion and 2) creates a starting point for developing countermeasures. I often find that the team can't stop themselves from offering "solutions" as we go through the root cause analysis, so I capture them on a separate flipchart as we ask the Five Whys. The next step is to figure out what countermeasures will prevent the root causes. Once the team has figured out the Five Whys, diagrammed the fishbone, checked the logic and identified the root causes, it's easy to create a fishbone diagram in excel using QI Macros automated Ishikawa/Fishbone template. One of my early projects had a fishbone that covered every wall of a conference room. Understanding the contributing factors or causes of a system failure can help develop actions that sustain the correction. The only tarpit is whalebone diagramming when the project is too broad. Overview: Root cause analysis is a structured team process that assists in identifying underlying factors or causes of an adverse event or near-miss. I have found that a properly focused improvement team can find root causes easily. Although, fishbone diagram combines brainstorming with a type of mind map template.
