Root cause analysis works only when it is driven by evidence and clear hypotheses
When something goes wrong, it is tempting to latch onto the first explanation that sounds plausible. In root cause analysis, the starting point is different: every explanation is treated as a hypothesis, a specific guess about why the failure happened that has to survive contact with the facts. A good hypothesis fits what is already known, keeps assumptions modest, and makes a clear prediction you can check. For instance, you might suspect that steel tubes stored near loading dock doors rust more often because they are exposed to damp outside air.
That kind of statement already has the structure the method needs. It singles out a factor, such as storage location, and implies what you should observe if it is right: more rust on tubes near the doors than in the middle of the warehouse. Hypotheses in this approach are never finally proven. They are either rejected or they remain provisionally supported after tests fail to contradict them. Over time, the better ones are those that repeatedly survive attempts to disprove them.
To keep this process from turning into random trial and error, the underlying scientific method is broken into practical steps. Observations of defects and conditions are used to form a tentative hypothesis. From that hypothesis, you work out what concrete results you ought to see if it were true, then design a way to look for those results, whether through a formal experiment or a structured check of existing parts and records. The outcome of that comparison feeds directly into the next hypothesis, which should now reflect what you have just learned.
In many organizations, this logical back-and-forth is organized through the Plan–Do–Check–Act, or PDCA, cycle. Plan means defining the problem and selecting a hypothesis worth testing. Do is the test itself, from a lab trial to an on-line trial in production. Check is the comparison between what the hypothesis predicted and what actually occurred. Act closes the loop. You decide whether to confirm the result with a more thorough test or to reject the hypothesis and start a new cycle. Each turn of PDCA sharpens the hypotheses and narrows the possibilities, so investigations move step by step toward the conditions that truly enabled the failure.
In the next section, you’ll look at some concrete graphical tools that help gather and organize the evidence those cycles depend on.

What is Root Cause Analysis about?
Root Cause Analysis (2014) explains how to investigate quality problems systematically using empirical evidence and structured methods rather than intuition or blame. It introduces the theoretical foundations of root cause analysis and then shows how to apply cycles of plan–do–check–act together with a range of quality tools to identify underlying causes of failures in manufacturing and service environments.
Who should read Root Cause Analysis?
- Operational quality and process improvement engineers
- Manufacturing supervisors and frontline problem-solving facilitators
- Curious people seeking practical root cause skills

Great app. Good selection of book summaries you can read or listen to while commuting. Instead of scrolling through your social media news feed, this is a much better way to spend your spare time in my opinion.
