Root cause analysis is a procedure that is widely used for the purpose of finding the main cause of any particular problem. The reason behind the identification of root cause is to come up with an effective and suitable solution to a problem that is under discussion. There are bundles of procedures that can identify the cause of any happening. The thing that makes root cause analysis different from other methods is its procedure to solve the problem simultaneously.
For example, a child accidentally threw a ball towards you, and it hurt your eye. In this case, if you only take a painkiller, it would be enough to cure properly. The painkiller will only work for aches, but what about the mark on your eye? For the external treatment of eye, you have to go for some other strategy on an immediate basis. That is how you get systematic prevention from any issue.
One of the best ways to do this analysis is with the help of a tool. With the help of certain tools, you can better maintain the quality of the procedure and its end results. Therefore, this article aims to discuss some tools that can work well for root cause analysis.
What Are The Best Tools For Root Cause Analysis?
The first step in root cause analysis is the identification of problem’s origin. Furthermore, you have to solve problems with quality control. The problem-solving is not a simple task, but it needs an appropriate target for the right management. It is better to use best tool based on the need of hour. It means you cannot use one tool for all problems, but each problem demands particular treatment. So, following are the tools that can work well in different situations:
Pareto Chart
Pareto Chart is the simplest tool that works very efficiently for root cause analysis. The best way to define Pareto Chart is the simplest but most powerful tool. With the help of this tool, you can better manage the flaws in procedure. Before working on the Pareto chart, you have to ensure data collection. For this, you have to specify the problem for which you need data collection. After this step, it becomes easy to have a plane line to follow for finding a reason to identify the cause. You can assume the list of causes, and then the Pareto chart helps you finalise one cause with respect to the progress of selected lines.
Now, the next step is to make a Pareto chart. The easiest way to generate a Pareto chart for root cause analysis is by using Excel. If you want to make your chart more productive, some other platforms can also be used, including EASE. So, whatever your platform is to generate a Pareto chart, the beginning is from observation, and then you can tally your data. For each assumed error, you have to find the occurrence of event. Once you are done with this, you have to re-arrange based on the basis of occurrence and make bar charts. After that, you have to add a cumulative line that tells you the root cause of the selected problem. You can also get dissertation help online if you are unable to add cumulative line.
The 5 Whys
One of the best ways to recall the cause of any problem is with the help of 5 Whys. This tool is used to find a solution for designed problem in a productive way that costs you very less. This tool works well to remove several layers of a problem one by one. The step-by-step procedure makes it very easy to understand the whole scenario. Here, you have to focus on the reason behind an event. When you repeatedly ask WHY, it leads you towards the root cause. In simple words, you can also take it as 5 Whys for 5 facets of the problem. For example, the following 5 facets can be targeted in root cause analysis:
- Why did an event happen?
- Why could the owner not get an idea about that happening?
- Why did the visitors not respond to that happening?
- Why was there no immediate solution for a particular happening?
- Why has the supposed solution for a particular happening not revised for a long time?
These 5 Whys can help you get the root cause. The answer to each question must be logical and authentic, leading you towards a constructive solution.
Failure Mode And Effects Analysis (FMEA)
If the concept of root cause analysis is new to you, there needs to be a basic start that does not confuse you much. Failure mood and effects analysis is a tool that helps you get the best end results in an easy way. It is an organised and empirical methodology used for the identification of a cause. Whenever you find any chance of turning towards incorrect results, it will be considered as a failure mode in the analysis.
In failure mood and effects analysis, you have to highlight SOD which includes severity, occurrence and detection of the root cause. With SOD, you can yield a risk priority number (RPN). Based on the results of RPN, you have to take control and evaluate which control can bring it down, then you can apply corrections for it. For most people, it is the most difficult tool. It is not wrong to say that failure mood and effects analysis seems complicated, but the only game is about the basics that make a foundation for analysis, and you find the root cause systematically.
Besides FMEA, you can get assistance with scatter plot diagrams or fishbone diagrams. These tools also address the problem after getting insights.
Final Thoughts
The above-mentioned tools are easy to operate, and you get the root cause of a problem in no time. All you need is to have good background information on each tool and a systematic procedure to follow. Also, you cannot go for any tool of your choice, but it is a problem type that defines the use of a particular tool.
