You can have major causes as the main branches while minor ones form the sub-branches. With the head facing right, the causes shoot off to the left, looking like fish bones. When drawing the figure, the root problem is at the head of the fish while the causes fit into the spine.

Zosi offers an online root cause analysis training solution. Even though they are considered basic, they still encourage you to keep searching for the initial cause of the incident or nonconformity that occurred. Conclusionīoth the 5 Whys and Ishikawa methods are considered two of the more basic methods of root cause analysis. The Ishikawa Diagram considers many factors that may have caused the initial problem by dividing the causes into finite categories within production. In manufacturing, the Ishikawa method is also called the 5M Model:įor food, these have been transitioned to:

Causes act as a source of variation, which is then grouped into categories to identify and classify the sources. These diagrams were first used in 1968 by Kaoru Ishikawa. From there, arrows indicate where causes can cascade into a nonconformance during the audit process. The Ishikawa method divides various root causes into categories (which are not predefined). When the “5 Whys” method is too basic, the Ishikawa method may be more appropriate. Also, this method relies on experienced staff to know which questions to ask. Depending on who is asking the question, you may get different causes. Unfortunately, the results of this method are not always repeatable. By repeating this question, you go past the superficial answer. The whole point of this method is to keep asking why to find the source of the issue. It is “an iterative, interrogative technique used to explore the cause-and-effect relationships underlying a particular problem.” The 5 Whys method benefits companies because it encourages deeper probing. The 5 Whys method is more or less like a toddler-just keep asking, “Why?” until you get to your true “because.” The true definition is a bit less straightforward. The 5 Whys is the method commonly used by facilities who are certified by GFSI standards. There is no set way to discover the root cause, but let’s explore two of the more common, simple methods. Outline who needs to do what in order to fix the nonconformity. Once you identify the root cause, it’s time to implement a proposed action plan. Has the immediate correction or corrective action been completed? -Even though you realized what happened, make sure that the immediate cause has been identified and corrected to prevent additional incidents or nonconformities. When did the nonconformity occur, and when was it discovered? -Identify the time period when the issue happened and take into consideration how much time passed between when it happened and when you realized it happened.Īre there any products or processes that may have been implicated? -Follow the incident to any later processes to discover what products may have been impacted as a result. What is the nonconformity? -Consider what is going on in your facility that needs to be addressed. In order to perform a root cause analysis, you need to gather the facts and evidence for the issue that’s occurring. We’ll explore both of these methods and show how each method has its merits to food manufacturing and production facilities. Within Root Cause Analysis, two of the more common methods are the “5 Whys” method and the Ishikawa, or fishbone, Diagram. By identifying the underlying cause of any incident, you can further prevent future incidents from happening. Root Cause Analysis is a method used to find the source of a problem once a problem has already occurred. Posted by Zosi Team on MaTweet Share Share How Root Cause Analysis Strengthens Your Production
